Hi people,
I have here passat 16tdi with pcr2.1
I do id with kess, ecu is locked.
Download vr file, do egr off and tune.
Write 100% at the end i had "wake up error"

Now car no start and no more id. I try connect with vcp, no communication.
Also recovery no more possible.

I dont open ecu, just write flash and now this problem.
Someone idea how to fix?

K-tag genuine and write full by boot, next flashing frf and works, X17 up this ecu on file from server magic by obd.

your problem is not kess but internet connection, kess when flashing ecu download from server files if internet connection is not stabilished Kess preaparing Ecu but not start flashing and now ecu is in recovery mode. Read again what he show before programing.

his problem is few bytes changed in section 1, you should never ever touch section 1 from pcr vr file (make sure you dont have anything edited from 0 to 180000).

x17 recovers this without problems, dont know for other tools

Problem is now, i don't have communication, nothing, with no one tools.

Is there no way to write flash (don't have X17)
I have:

-Original VCP
-Original Kess
-Original Autotuner

-clone abrites
-clone vcp
-clone ktag
-clone fgtech

I dont know, in other post you write " I have genuine K-tag " now you not have this K-tag.......... Use autotuner and try flashing vr stock file, In Belgium People not have x17?

No bro, i don't have geniune ktag. We buy it, but need to take him in Turkey, because there is no transport to here without VAT.
I have friend with AT, but he don't take the phone..

We are in shit here

hehe.....

I know smok you also not have, but maybe someone near you... it also read/write in boot modus...
but donīt know if itīs possible to solve your problem...

Ask Alientech support online who should help you
They might ask you to send the Ecu somewhere near you where it can be fixed

Hi M8, did you tried to make recovery using ksuite 3.x and downloaded vr file??
This should work!

Yes even the original file you had put back on recovery mode it should work as well
I thought you’d tried already

recovery not work. I tell what doing to revive this ecu, need only tools...

take on table ecu...do not open
make wired conections and use pinout...and connect on table with obd cable of your tool...rewrite ecu with your VR file using option "on line unlock" or NOt online unlock...if there are thoses options...i use original fgtech when happened this shit...qnd work...important is that you have the virtual file downloaded

You have sheme of obd to pinout?

Update: changed the vin to original car. Write sgo.
Now all sw hw vin chassiss is same of the original car, also chassis vin.
Now tomorrow i adapt ecu with odis engineering online and hope car start


Someone do this job?

Update:
no work with Odis engineering after change vin sw hw.

Someone have scheme for read on bench with pinout?

I no need picture what fgtech or Ktag have, i need sheme for put wires in obd2 cable and read/write on table.

Tryed with magic X17 without sucess.. i don't know what is problem, very strange...

Tomorrow i go to friend he have ktag. I hope i can write flash with tricore. X17 cannot write flash with tricore..

hello this happened because ecu is still locked you need to download an frf file and convert to bin and write again via kess this will solve your problem

Nope, it doesnt work.. no communication

Problem is because ecu in in programming mode... And you can not get out from this... In edc16 there was bdm, but here you can not program it directly

sdtsedat
27th November, 2018, 03:27 PM
No, thats not the problem. I tryed with X17 and ktag do acces directly in flash.
If pcr ecu is locked, and you will do over obd, you no don't may edit values till 18000

If you change 1 bit or more under 18000 ecu will block and never wake up.
If you unlock, no problem.

Dealer called me, he put new ecu, adapt it and car start ok.
This thread can closed.

If someone have this situation ( i hope not) i try to help..

I have repaired 2 of these, it is the internet connection 100% that causes this problem.

Do not do on a personal hotspot with mobile phone.

Must be high speed broadband. A lot of mobile tuners seam to damage these.

I repair these with genuine KTAG using the new (P944) protocol. You also need an additional cable SSM 144300T111.

easy to recovery, 3 times I kill this ecu and reapair, need only genuine tools how saw user wiseman.

I write with wifi 2.4GHZ 55mbit.
And try with geniune KTAG P994, only commumnication with eeprom. No communication with flash MCU/MPC. I cannot write or read.

edc17 is like bios... It has bootloader inside... And if you change first bytes than you destroy bootloader, which is needed for programing via ktag or via kess or via any tool... If now someone understands.

I bricked my with kess.... I read file first with vag can commander... Done egr off and than I write with kess (I assumeded that file read with vag commander like read with kess) Ecu was also unlocked before me. When I wrote egr off with kess ecu get bricked... Than I get file which was read with kess and 100% fits ecu sw numbers... And I compared file with my file read with vag commander... File are 100% same from some address but there is alot of differences at start of the program

but you have unlock ecu, this is another situation. Kess not preaper ecu to programing mode, you change only flash area, galetto write stock file wothout any problem and car start, tested many times.

You can recover this when tool can do id of ecu otherwise i dont think so.
But i never had a issue with pcr after writing so cant argue about it.i done thousands of them with fgtech on bench and x17 by obd...
Not one issue...so maybe kess is the problem..

I read it maybe late but here is my experience.
When I have to work on pcr, I always open it and read full with X17
If something goes bad you can save yourself.

first solution working on ALL tricore : changing the cpu by a new one and reflash it, the new one doesnot have OPT active and programming tools don't activate it too, so you can flash what you want on it like on an edc16, the ecu can receive a clone file.
hard point : find someone who can make bga soldering with IR station

second solution : read HW version written on the ECU and buy an used another one with the same version or higher, read it with X17 and send all dumps to magic motorsport, they send you a new eeprom file and frf file, write all with x17 : done
The eeprom file is adapted to your car with pin cs mac ....
plug ecu on car and write ecu coding with a diag tool (vcds, launch), then write injector codes
finished !

remember : all dumps needs to be read with X17, else MMS refuse to work on it, they ask log files from their tool. Some people perform the adaptation like MMS but I didn't try because a friend have x17.

AVDI original can adapt used ecu alone :-) !
