Hi guys,

the story in short. Due to a turbo (k03) defect I reduilt my BWA engine straight to an CDLB (TTS) engine and my Idea was, just to buy a TTS ECU from ebay to get may baby running again.....

Back from my garage and for anybody who thinks about doing the same - I must tell you - I dind't go :-(


Immo off - perfect, no problem. Changed the BWA ECU to my spare ECU out of an TTS (CDLB). Starting the engine - some minor pops, but in principle running smooth ..... but the dashboard light up like a christmas tree.


Got 3 serious errors:


012313 - Ventil für Abgasklappe 1 (N321) - P3019 - 004 - Unterbrechung -> this one I think is not a big deal, just because my "Normal" TT do not have a flap exhaust system, so the controller is missing.


005000 - Steuergerät defekt - E-Gas Überwachung - P1388 - 004 -> This is one of the bad ones - the TTS ECU do not recognise my e gas pedal. So engine runs in saftey mode.


000256 - Luftmassenmesser (G70) - P0100 - 002 - Versorgungsspannung -> and there's also a problem with the supply of my mass air sensor


According to the errors above also my ESP and brake controller reported some very strange errors :-)


Yeah at the end - switching back to my old BWA ECU, deleting all the errors and now everything is fine again. It's a pity but these two software versions seem to be too differnt to just swap.


CU guys and thx for all the help - have to think abaout, what I'm doing now....

Use old ECU and tune it :)?
The best and easiest solution in my mind.

Of course you are right - but I'm a little bit "strange" sometime, and I'd really like to keep my original ECU as it is. You know,, with a flash count of "0" ;-)

What is your opinion - If i get a full BDM of a 8j0907115H SW 387549 - I mean CPU, Flash & EEProm - is it possible to "overwrite" the TTS ECU to a ECU like mine?

KTAG offers a Restore function with all three "elements".

Best regards,

You could erase flashcounter... or why dont clone em and tune then?
I never test and be very carefully with doing this things :/. Some ecu works another dont.
Would get same HW and clone + tune there.

Dear Lambda1,

yes you are right - I'll sell the ECU on ebay again and go for the same one like mine. It would be the best solution i think :-)

Yes I can "delete" the flash count via changing the eeprom data, but I don't like to open my orignial ECU for this :-)

I dont care why :D its your turn...
Also flashcounter isn't zero... its flashed by VW... so only theoretically zero but real is fc=1.

You will match it.
