Audi A4 2002 RB4 problem

[aassfour]

here is the story :
i was using VVDI2 on this car to make a spare key. on autodect i got the Pincode 5996 and i inserted 2 keys to learn. but it refused to take my transponder 48 m1 and m2, customer has m1.
so i went to 4th immobiliser audi and choose A4 instrument with crypto RB4 , and read immo data and i got pincode 38021. 403923 so i prepared a dealer key and made add key. and both keys stopped.
so i had to make immoOff to make the car run again.
but on cluster the RPM needles stoped working and oil check on screen and the turn light indicator not showing even though they are working plus the low and high beam indicator no showing on cluster but they are working.
i made actuator test on the cluster and all seems to work well. but when i run the car they r not. Mileage is ok , the timing is OK.
i know that the eeprom got corrupted while i was adding key cz when i read again the immo data i got all bad reading.
Does the eeprom has any link with RPM , OIl , and Light so they not show on cluster or get disabled ?

things i tried was
,1writing another dump into cluster where i got DEF and still the RPM and Light and oil problem.
2 tried to virgin cluster by vvdi2 option and reset it , for a second u see the light and rpm moving then back to null
3 tried to write back the immodata i saved , but is says success however when u read again its still corrupted.

PS: when we made immo off we removed cluster to kill the immo light and put it back when we noticed the problem so i m not sure if the problem from before or after we removed cluster ..

any help is appreciated :

cluster dump : 403927
Ecu dump :403928

I think you should go first to Audi Immo4 RB4 crypto. You cant add key only with PIN in this clusters (only when you have key from dealer I think). Before do anything next time read manual 5 times !!! VVDI2 should not have this option in Key Learn active for this kind of dash !! I didnt do RB4, RB8 with VVDI2 yet I have it short time but maybe someone here confirm that it does spare key job good if you choose good option ??

[yugo45]

You have none crypt rb8 cluster.

I think pin 05996 wa good pin , all you need to do use VCDS and program keys. But now since you have Rpm not working , I think you will need other cluster.

[jakesman]

maybe u can use carprog to repair the cluster " Audi 2J74Y repair software for CarProg" then start over

Hello.
friend the car dash is RB4 not magneti marelle to solder wiring to repair by carprog.

[aassfour]

So this RB8 !!!
So there is where i went wrong.
What are my option here ?
Other then getting another cluster.
So i guess they stopped working cz flash is corrupted ?! Where is the flash in this cluster

Cheers

2002 should be RB4 and at least in North America do not require a dealer pre-programmed key, it adds the 7 byte CS to the key the first time it is programmed (must be virgin id48 or id48 audi can chip if not a key already programmed to the car before).

If you can re-enable the immobilizer try with the pincode using vcds or similar tool. Watch out for lock times, could have been the cause in the first place. It should also only have a 4-digit skc (plus leading zero), so keep that in mind. At least in North America I have not seen an RB8 cluster before 2005.5 (not sure if it can be retrofitted but have not seen one from the factory that way)

thats wt i thought 2002 is RB4. Original key wasnt Can48 , just normal even that when i was trying to program the key it showed Dealer Key : NO for new transponder, i prepared the can48 and added CS with tango , Still showed Dealer Key : NO ....

does this cluster has Flash ? or its the eeprom that was corrupted ?

who can confirm if it RB8 or RB4 ?

When you read "A4 instrument with crypto RB4" and got pin 38021 what mileage did you get? Was is it correct milage as it is shown on instrument cluster display?

[aassfour]

mileage on cluster was 199xxx , when reading it was 222xxx

[dtip]

mileage on cluster was 199xxx , when reading it was 222xxx

Well mate that was first sign you had bad reading and should not do any writing/programming. You probably had rb4 non crypto and should be read like that

i m aware that i did wrong, but no one is giving an answer for a solution if there is any.
i dont care about the Immodata anymore. the car is running , but as i said the problem is the cluster , RPM , Light and OIL.
they stoped bcz of corrupted FLASH ? where is the Flash ? Can we Read flash ??


Thanks for solution

[dmp]

Not sure if this will help but I remember reading that the immo off can cause those issues. Is it possible to reverse the immo off and see if you can program the keys back in then?

[magneto21]

I agree with - yugo45
Don't waste your time it will by very hard to fix it ,just get another cluster- is very cheap, and program with VCDS- 3 min. job....... ,by the way, I just checked your dump from cluster it's RB4 .

Regards

Not probably, 100% non crypto Rb4 , I gave him answer in post #3 .

Hello.
1) Dear about my post in #5 i right it by mistake,your dash rb4 i know you know it well it rb4.
2) the problem not yours the problem was from vvdi2, some dashes on rb4 you must read pin from engine ecu and add key by vcds, cause avdi original too haz same problem on some dashes give wrong pin from dash ,but avdi don't corupt data. So your solution contact me .

[amigokola]

Haroutioun please post here solution to fix this dash. We want to learn to...
VVDI2 should have better AUTODETECT for this kind of clusters !!!
So with VVDI2 better not touch RBX-clusters ?? Maybe someone here has some more experiance adding key with RBX clusters by VVDI2 ??

[jakesman]

404046this might be stupid from me i dnt know it all but why not use the old kkl cable with vag eeprom reader and see maybe if u are lucky it have a function that u can edit dump "set as new "

AVDI and VVDI2 has the function to make it Virgin Factory. i ve tried that when i was selection RB4 cypto. i m gonna try that tomorrow but selecting RB4 non crypto, and i will remove immooff and reprogram the key original with VCDS with 5996 pin code.

Hello.
1) Dear (amigokola) simply always we must be careful,for axemple, see what kind dash rb4 or rb8 encrypted or without,our friends (aassfour) dash rb4 uncrypted, and his dump not corrupted see the pic i load here after i loud his dump as our friend (jakesman).
2) vvdi2 is good you can trust but vvdi1 or vvdi2 has problem with k-line instrument.some times you must remove ecu to read dash or remove dash to read ecu,very weak on diagnos vvdi2 and avdi. for that always get pin from engine and adapt by vcds,on some dashes rb4 you can't adapt dash to ecu or add key by avdi and by vvdi2, cause they have problem device, just vcds can do adapt, long times or years ago i send emails to avdi supports to ficks this problem but no result. any way if you have any question let us know.
Ps: vvdi2 is OK by rb8.

[aassfour]

so if dump not corrputed , wt made the RPM and Light not working and OIL shown on screen ? is it the immo off ?

Hello.
Dear,if you have vag eeprom programmer try loud your dump and write to dush. after i think will solve by writing vag programmer. you can return immo on, but not the immo off the problem of rpm light oil or xxx. try and let us know the result.

So i guess redumpin the cluster by obd wont work . I woll remove the 24c08 and redump it manually but not by vag eeprom programmer cz i dont have that

[Weasel3]

404070Please test.

[yugo45]

Does anyone reading my posts ???

This is NONE CRYPT dash , and all he needed to do read pin the adopt keys with VCDS. In VVDI or AVDI it will be under K-line dash, "AUDI A4 Bosch Rbx".
If you read it as CRYPT dash and adopt keys this way, write sec block in it , you will brake cluster.

Also it could be broken when he remove LED.

Best solution get other dash and adopt it to car.

this is what puts me off chinese tools

ok i can get a cluster and change it i know that and i know it wont cost a lot. but i wanna understand the idea of wt is corrupted if anyone knows. finding a fix is always better then changing the item since the dump is saved and still not corrupted. what makes these RPM and Light and Oil not working ?

and i dont think bcz we removed the led we broke it , since when you test actuator they r all working and not broken.

[purdy]

I've just bought vvdi2. This is interesting stuff. How do you tell which dash you are dealing with if auto detect doesn't work that well ?

sometimes it works , and sometimes it doesnt . i just find out that its not working most the times. i ve done many and they have worked but this car didnt. so i guess like the members here said , get pin code from ECU and adapt it with VCDS

Am i missing something here :) ? I think this has nothing to do with chinesse tools or autodetection and simillar.... I dont know why people in this post won't realise that he just manually choose WRONG type of cluster when he was reading :-) and probably would not damage it if he did not write back file or part of file (when adding keys) , that was only problem or i am wrong? As i said you can see easily see if you had wrong read or not by comparing mileage from read file and actual on cluster...at least for AVDI.

[paul_12345]

can't you simply get another dump, then make it virgin, then use the pin from ecu + vcds to adapt the dash.

i will try that as well tomorrow

[amigokola]

Yes you are right.. And thats what I wrote in post #2 but I assumed wrong that it is RB4 crypto dash. If I had one VVDI2 I would probably do the same mistake. When I connect supervag.com it connect's and autodetect automatically dash type and its cool. That is lesson for all of us to check 5 times before start key learning or sec block writing procedure.

Yugo but the main thing is how to check if it's non or crypto ?? By comparing dash milage with eeprom milage dump ?? VVDI2 when key learn should say precisely what kind of dash we deal with so there will be no mistake. PS: There was RB8 non crypto dash ????

Obdsystems I know that you are aware of multiple damage that AVDI did in past so leave it to yourself...

@amigokola Is it possible to check as i sugested and sugested in Avdi manual (i dont have VVDI but i asume software is same or similar as FVDI) - read as RB4 crypto and if read mileage is not same as showed on cluster than read as RB4 NON CRYPTO and compare mileages then??

In This case on RB4 cluster Simple solutions with Pin. If you get 5 digit pin you have NONE crypt cluster. Also you can compare Immo block with Crypt one and there will be big difference.I always said , it is not tool that makes perfect job , it is person who using it.
When you read cluster there will never be damage.
Damage comes with writing.

here is the story :


but on cluster the RPM needles stoped working and oil check on screen and the turn light indicator not showing even though they are working plus the low and high beam indicator no showing on cluster but they are working.
i made actuator test on the cluster and all seems to work well. but when i run the car they r not.

I just read your post again and This tells me that you brake cluster when you remove LED.
If you do pointer test and all is good, this mean Eeprom file is good ,because you are giving order to processor to do this.
But actual signal that comes form connector is gone.

[dtip]

Yugo what do you think about comparing mileage from read file and cluster as i mentioned earlier?

[yugo45]

Same thing as Pin, if miles not same then you have choose wrong cluster.
Any person how does this job professionally and pay tension should know this.

[exe123]

Actually this is not VVDI fault. It is 100% bad by user.

What do you do first? Read the dump and make a backup!
I never touch a dash without a proper backup.

RB4 crypto and non crypto can be recognized very easy.
Immo-ID in line 0x00 = non crypto
Immo-ID in line 0x50 = crypto

The dash can easily be recovered. There is no HW damage. Just the parameters are ~~~~ed up.
Get a proper 8E0920900H D22 dump, write it and learn with VCDS. Job done.

Edit : Virgin 8E0920900H attached. Pin is 05996

[aassfour]

hi , Problem fixed
i ve removed the 24c08 and tried 5 dumps from the forum , only this own 404161 worked and now all on cluster working well. so it wasnt damaged cluster, it was just the dump corrupted. when u read it u think it looks good but as exe123 said , some parameter were bad ...

Cheers all

[exe123]

You wrote a non crypto color dashboard file. 8E0920930G
As your dash is normal FIS 8E0920900H it will not fit 100%

A4 immo off will mostly not work as hazard lights will keep flashing and power windows will not work. Check that first.

i did , hazard light working only when i press , and window and ac and everything else are working gd.

What I meant when you read cluster and you get (Example 24875 Pin) then you choose wrong section.

Rb4 with Immo 3 always need to be 4 digit code .

would it be possible too get a copy of your virgin crypto file please I'm really really stuck on this problem too , Thanks in advance if not thanks anyway
