VW Touareg: No ignition and ELV defective in dashboard

[paskuale]

Hello mates,
I have VW Touareg 7L year 2007 3.0TDi engine BKS.
This car does not power on ignition and in dashboard I have message about faulty ELV.
When I insert the key in the ignition nothing happens: the steering column is always unlocked and I can't power on ignition.

I have error in 05-Kessy module:
00288 - Steering Column Lock Actuator (N360)
014 - Defective

If I erase this error and remove key from ignition, the ELV try to close and then open again. And message in dashboard about ELV defective.

ELV part number is 4E0905852E.
This is pictures of PCB:

Does anyone has experience with this fault ?
It's an ELV problem or can be a Kessy problem ?

Any news about common failure ?

Thank you
Bests

[paskuale]

Can Someone help me please ? :(

[paskuale]

Someone told me that this problem can be a corrupted dump in Kessy module (like BCM2).
Is it possible ?

Mate Inside is a MCU ST72334.
Is possible read/write this MCU ?
Or I need to swap MCU ?
This ELV is adaptable to car only if it is virgin.
Thank you

Mate I already read Ross-Tech wiki...
Do you read my questions ?
Thank you

Only way to fix this is to buy new EVL and adopt it.
You can not adopt second hand EVL .
I never seen any other solution for this.

Yes, I know it.
I have genuine AVDI, and it can be adapted only if ELV is new and virgin.
But I can try to swap MCU from my ELV to another working ELV and see.

[paskuale]

switch im*o to off EDC16C34

Switch Immo off will not help me because engine ecu is correctly adapted to this car, and without ELV you can't make ignition ON.
On this car you can't make ignition on with immo off.
Immo off will only help to change engine ecu without adapt it to kessy module.

If you think you have mechanical problem with Actuator, then you can swap whole board to second hand ELV.

[paskuale]

Tried to swap the whole board to second hand ELV: the ELV will close and never opened.
On dashboard have "Immobilizer active" and car does not start.
Can someone help me please ?

[Pyromaniak]

Try open lock, and make it lock, then try it.

Try resolder all on pcb on ELV

[paskuale]

Do I need to put ELV in locked position ? And then I have to test it ?

Do you mean resolder every component on PCB ?

[Pyromaniak]

yes put to locked position and than try ignition on. Yes i mean resolder every on pcb.

[paskuale]

I tried in lock position: when I insert key it unlock and in diagnose I have error in kessy about defective ELV.
If I erase error car will start, but if I remove key I have the same error and I need to erase it again to start car.
I resolded every component on pcb and no-luck :(

[Pyromaniak]

I think motor in lock need open and cleanup comutator (this is where brushes coming) motor have small torgue. you have two elv? try change mechanic part from donor elv

[paskuale]

The problem was not mechanical part of ELV.
I use the original motor and original mechanical part, but swap original MCU on new pcb board and problem solved!
I think problem was in hall sensor for close position, when elv close it make some noise and motor not stop...
Mates thank you for any help :)

Hi,

I am having the same problem on the cayenne. Did you transplant your MCU to a used unit or a brand new unit?

[paskuale]

I soldered my MCU on another good used unit with same part number.
bests

[mercuxio]

Ordered a used steering lock from Ebay (had to find hard for one that is younger than mine :)) Did the exact same thing. Transplanted the MCU from my original board to the replacement one. Used the replacement as a whole. Now the cayenne is no longer a paperweight.

I strongly believe the part that failed on mine was one of them hall sensors. One gave weird resistance readings compared to the other 2. They (all 3) were the same sensors.

Thanks for the pointers

[Audi SP]

hI,
I have the exact same problem..

so if I buy used elv I can solve?

[paskuale]

Yes, you will solve with another working ELV.

[lashkar97]

its only problem of motor i replace many time only motor and job is done . remove motor and put there china motor elv will work like new .

[paskuale]

Not always is motor issue.
I repaired two VW Touareg and never motor was fault.
You can test motor with 12V

[yunchuli]

I have the same problem on my Phaeton 2012, is the MCU the one marked with 72334/MTN...?
Where did you get the good used unit? Is it difficult to swap the MCU?
Anyone tried placing relays (tyco v23086-c1001-x008) instead? I search it in google and found a few results mentioning the same problem: https://www.yoycart.com/Product/532789339630/

Thanks

[paskuale]

You can start by change relays, they are a common fault on this unit.
In my two cases I had problem on other component, maybe motor position sensor.
But always I swap MCU on another good ELV and solve the problem.
It’s not much difficult if you have good soldering skills.
I found they in scrappy.
Good Luck!

Thanks for replying, paskuale. I would like to purchase a good ELV but I don't know what's "scrappy" as I lived in Taiwan. I will try Taobao or ebay instead. Do you know what's the MCU model in 4E0905852E ? Just a backup solution if I ruin the original MCU...
How do you disassemble 4E0905852E? Any special tool required? I have it in hand but not sure how to disassemble it...

[paskuale]

Hello my friend!
Scrappy is scrap yard, where you find broken cars to sell working parts :)
If no scrappy in Taiwan you must use eBay or something like this.
You can’t read the MCU in this ELV, so you must swap it from broken ELV to working ELV. Don’t try to read, you can erase it and then only dealer can help you with new entire steering barrel because ELV is not sold lonely as spare part.
To disassemble it no need any special tool, only you have to unscrew the two security screw on it. You make a slit and then unscrew with flat screwdriver.

I can't find the 2 security screws on the ELV. I found only one piece of plastic near the connector. I will share a picture of it.

https://ibb.co/hEbGDo

[paskuale]

Ok you already removed it from steering, so you already unscrew the security screw.
At this point is very simple open it: you have to remove the metal cover on the connector side.
You have many folded edges that hold cover it in place.
You need to straighten up these and then remove the cover.
Please if my post helps you push thanks button :)
Bests

[yunchuli]

Thanks, paskuale. Now I removed the cover. I can see the PCB with only 2 screws. Then I unscrew them but seems the PCB is still attached to the ELV case. I didn't dare to pull the PCB out. Any suggestions?

[yunchuli]

By the way, how did you test the motor is working or not? Simply apply 12v on the terminal?

[paskuale]

Hi mate.
After you removed the two screws you can gently push out the pcb. You need to apply some force because motor terminal are pushed on pcb contacts, don’t worry.
To test motor you can apply 12v on motor terminal, but you must remove pcb first! When you test motor pcb and motor must be disconnected!
Let me know!

[yunchuli]

Thanks, mate. I used a thin wire in the 2 screw holes to pull it out. Now I can see the motor inside the case. There are two terminals on it, so if I apply 12v on it and motor and mechanical parts move, then I can be sure the motor is working properly? Thanks.

[paskuale]

Hello mate! In the first picture you can see the two power terminals of ELV motor. Apply 12v on both terminals and you can see the motor will moove (if it works). To make it moove in contrary you can invert 12v on the terminals.
Pay attention when you make this test, be sure that 12v are only on terminals and not on metal box of ELV.
The motor will start rotate at high speed, when it arrive to end point you will hear “ta-ta-ta-ta” and you must remove power.
Let me know!
bests

[yunchuli]

Hi mate. I applied 12v on the terminal of motor and the motor rotates in one direction. Then I tried the other direction by inverting 12v. At first it won't rotate, then I increased the current limit to 2A and it rotates. Now the motor can rotates in both direction (with 1A current limit). I guess the motor and mechanical part is fine. Looks like I need to find a good used ELV to transplant the MCU.

[paskuale]

I think the same my friend !
Search another ELV with identical part number and final letter too, but with most recent production date and swap MCU and you will be fine!

[yunchuli]

Hi mate, thank you for all the details provided. One further question, do I need to assemble and install the steering column back to the car then test if transplanted ELV works? Or simply connect the cable to the ELV's connector and turn the key to see it gives ignition or not? Any risk if not install the steering column back the car before turn on ignition?

[paskuale]

Mate you can just connect ELV to the car cable, no matter if ELV is on steering column or not!
You can test it without steering column too!

[yunchuli]

Mate, I soldered 2 new relays that I received from vendor in china but no luck. After clearing the fault code and insert the key, the ELV is not moving a bit and the same fault code (00288, 014) appears. I am going to check the fuse box to see if there's any blown fuses. In addition, I am checking the ebay for the good used ELV, however, I can't find any near Taiwan so far. Is there any ways to bypass the ELV and start the car? Otherwise, I need to buy it from overseas and takes so long to get it....

[paskuale]

As I know, no way to bypass ELV on this car.
I advice you to find another ELV and solder your MCU on it...

[yunchuli]

Hello, mate. I got it fixed, finally. I would like to feedback my experience:

0. When disassemble the ELV, be careful when pull out the PCB, apply the force evenly on the PCB so it won't bend the plastic stick
1. Try replacing the component on the PCB with new one where I found in some vendors in china: V23086-C10010-X008 and HEF4047BT
2. Use 12V to drive the motor to locked position (in my case, my ELV dies while locking, so it's not locked)
3. Clear the error code in J518, if the error code is not cleared, the J518/ELV won't work normally.
4. Connect the ELV to cable and try again.

[paskuale]

Did you replace ELV or fix yours ?

[yunchuli]

Hi mate, I fixed mine.

[paskuale]

Which component do you change ?

[yunchuli]

relay and one ic: V23086-C10010-X008 and HEF4047BT

Hello I have a 2007 Touareg V8 7L and it has the same problem, steering wont lock, no power on ignition/ no start - I have a couple questions maybe you can help with.

1). What equipment do I need to generate and clear Kessy Elv error code to start vechicle?
2). Do you have to remove the steering column to access the ELV?
3). Do you have any pics of the MCU that you replaced on the new ELV?
4). If I disconnect the Neg Battery cable shouldn't that clear the kessy codes and car should start? (does key need to be in when i reconnect the battery cable?)

(http://www.digital-kaos.co.uk/forums/member.php/88420-paskuale)I tried in lock position: when I insert key it unlock and in diagnose I have error in kessy about defective ELV.

I Appreciate what youguys have been able to accomplish in fixing this problem, very well done. Thanks for posting!

[paskuale]

Hello dcasino, welcome on DK!
1) Every diagnose is able to clear error in Kessy module.
2) Yes
3) You transplant MCU from your ELV to donor ELV. I don't have pics now, but it's a QFP 44pin, simple to remove and solder.
4) No.

Your situation is normal in case of bad ELV, no news about it.
You can try to fix your ELV by changing relays and other parts (you find info in this topic) or take another one from junky and transplant MCU.

1). Not sure what equipment I need to reset error code in Kessy - Do I have to get VCDS software, Laptop and a $200 Ross cable or is there something else?
2). Will the laptop read error codes since inserting the key does nothing

[dcasino]

Bought a Tester for VW/Audi and i get no communication - key in, no power on, no start. This is what I was afraid of. I can't read/clear codes because
i cant power on with key. Does anyone have any suggestions

[paskuale]

What do you use to clear the error before ?
You can read/clear errors in Kessy with ignition OFF too because it’s inmobilizer module.
To make it alive just play with headlight switch or brake pedal.

Turn on hazard lights,(if not enough - press brake and pull the Flash to pass). These force the CAN Gateway to communicate.

[At Passat B6 can get Ignition with a jump on OBD socket, 1 to 16, but need to do at back side if you want plug diag to the socket.]

[dcasino]

2005 Touareg - Bought a scanner Thurs night that will read VW modules - can't scan anything (no communication) - I decided to jumper relay T15 J329 (B+) under drivers seat.

With jumper installed I can scan KW1000 module (Triptonix switch) and release that switch. i can now move shifter from Park, Neutral, Drive, etc to at least tow it to dealer if need be. Scanner says no communication with ECU module, not reading any modules - no power to cluster, no power when IGN on, no start. I did jumper Relay A3 in E Box under hood and starter turned engine over, but no start. Also no headlights, cluster power, Horn, interior window control. I do have radio, running lights, dome lights, brake lights, door locks, exterior window up/dn via key, proximity door unlock, sounds like kessy mosfets and resistors are ok.

Not sure what's in Vehicle electrical systems control module J519 but its next to the kessy and it sounds important. alot of systems seem to have no power but all fuses are good.
Also not sure what role Anti Theft Engine disable sensor D1 plays in all this, but also sounds important.

Do any of these symptoms sound familiar and any suggestions where i should start next?

[dcasino]

I have an update to my Touareg situation.... After 3 weeks of bouncing my head off the wall, with nothing to lose and nowhere to turn. I decided to purchase a Ross Hex 2 cable, downloaded the VCDS software, installed it, ran auto scan for DTCs (diagnostic trouble codes) low and behold the scan started reading kessy faults out the ass. (17 in fact). I reset the DTC codes and with a slight grin I wondered.... I turned the ignition key slightly to the right, the cluster came alive.. the bell started chiming, the cluster lights came on. I ran to the house like a giddy school kid. I told my wife " IT'S ALIVE" come see. I wanted her to share in the joy of what i truly believed would come next. With us both sitting in the Touareg, I pressed the brake pedal, turned the ignition key to the right, it turned over and with a roar, it started. Everything came back. The horn, the lights, ac, moonroof, interior window controls, wipers, blinkers. Everything was back as if it all were waiting for permission from the master. What a lot of anguish we went through. I was so close to changing out parts cause nothing was making sense. to many systems were down, all fuses were good, relays were fine. I just can't get past the fact that all i did was put a battery charger on it. I am truly amazed at what level they went to force you to have to take it to the dealer. Fault codes would not clear even with disconnecting the battery. It had to have special software to reset the fault codes. Folks all i can say is you better make sure when you travel to have your laptop with you, VCDS software on it and your ROSS TECH cable in the glove box. You never know when you may find yourself stranded and no idea what the hell just happened but the cars in acoma. Good Luck and to all who offered advice, Thank You!

hello guys,new member here,was looking at this topic for a while as i bought touareg with steering defective workshop on the dash,as see there's few solution for this problem,my module no is 4E0 905 852 C and theres few on ebay atm,shall i buy one and them swop/solder MCU from my board to the donor board yes??My Q is what's MCU?can some1 post a pic please??Or i better do what yunchuli (http://www.digital-kaos.co.uk/forums/member.php/582944-yunchuli)
did? My clocks dont working,steering isnt locked as i can turn wheel with bit of force.Thanks in advance

Hi mates,
I have the same elv but i find so dificult to open it about read mcu to write in donor one. Is there a way saffety? If we make a bench maybe we can match immo in donor elv by diag?
Thanks a lot ;)

[TESTASTRETTA]

I wonder if there is any cheap programmer which can copy the mcu to other elv unit. My xprog do not support this mcu :(

[Degi256]

you need swap mcu or virgin elv if not havz need buy new

[mercuxio]

Just an update, my fix of using a donor lock board has died after about 3 years. The donor board in which I have transplanted my MCU and replaced new relays has failed with some tiny burnt marks on the PCB for some reason. I suspect the humidity in my car (due to the boot lid leak) together with the recent non-usage of the car might have caused it.


Anyways, proceeded to obtain another donor lock from Ebay, did the same procedure but it failed to work. Very likely the donor lock had issues as well (some faulty components that cannot be seen with the naked eye). The lock was from a 2007 car. My previous donor was also from a 2007 car. My car is 2007. So it seems to make me think that these locks probably fails after an average of 10 years of use.


Got another donor lock from a 2012 car from ebay but I didn't use it (still unopened). Instead, I ordered an N360 emulator from China and transplanted the MCU together with the harness connector over. Works immediately. These emulators basically disables the physical locking of the steering and just returns the signal needed to deactivate or activates the immobilizer. Has a built in tiny speaker that mimic the sound of the motor locking and unlocking. I believe this to be a permanent solution for this problem plus the board is 100% new. I believe the board I ordered is an improved version 2 as it has the speaker fitted onto the board. The first version requires the motor to be removed and a speaker placed in that location. It seems to be rather well built.


What I have come to understand is that you do not need to clear the fault codes stored in order to have this fixed. My error code was "0288 - signal implausible" and I didn't clear it when it worked. Still haven't cleared it - Just waiting to plug it to a proper PIWIS when I can.


Attached are some pictures - since pictures speak a thousand words. Also I have a steering lock from a 2012 car (manufacturer date 17th November 2011 on the lock) and other loose components up for grabs if anyone is attempting this fix.


1 X Full donor Steering lock (untouched)
10 X V23086-C10010-X008 relays
1 X HEF4047BT
1 X perfectly intact hall effect sensor transparent plastic stick

Where did you buy emulator?

I also heard they not work with all EVL , only one type.

[mercuxio]

Where did you buy emulator?

I also heard they not work with all EVL , only one type.

The emulator works for cars with the same ELV. What I know is Audi A8, Bentley, VW Touareg, VW Phaeton and Porsche Cayenne uses the exact same steering column. Hence the same ELV. The Q7 and A6 is a different ELV and there's a different emulator widely available for that.

Having said that,

I have been getting queries on the emulator I've gotten. I'd like to clarify that I didn't get it from an online source. Instead, I gotten it via a local contact (friend) in China. Therefore, I really couldn't give you the distributor information.

The V1 of the emulator (pic below) was out of stock everywhere since May and the reason I came to find out was that apparently, due to the global shortage of ICs. Imagine my frustration, a non-moving car, plus it was blocking my other perfectly working cars in the driveway. I was desperate and got my friend in China to help search for something.

A friend manage to source the emulator for me locally in China. The seller didn't even ship internationally. It was shipped to my friend in China and subsequently shipped to me. I can't seem to find any information on this emulator on any websites even the China domestic ones. It's probably very new or they didn't care to market it internationally. It didn't came cheap, but still cheaper than a new steering column being a permanent fix.

If anyone is desperate to get this, drop me an email at ben@sotjor.com and I'll see if I can help you.

V1 not working on 2004 and 2005 cars , only 2006 , So I was wondering will V2 work on 2004-2005 . There is 3 different EVL ,original in 2004 , then 2005 updated version, then other updated version in 2006 till 2015.
