Audi a6 1.9tdi edc15 lost keylearns

by **Kuisma_** » Sun Oct 18, 2015 9:16 am

Read was ok and everything seemed fine, then remapped the original file and writed it back, write was 100% correct but car wouldnt start. Tool was mpps and the file size was 0.5mb and totally fine. How this could effect immobilizer to forget car keys? I can upload the files if someone want to look them up. I have vagcom but dont know how to learn the keys again, can anyone help?

Ive write tons of VAG EDC15 never fails...

What tool did you use? Obd or bench...

INmo sector in this ECU is not in flash, has dedicated eeprom ...

Login code could be finded in eeprom ECU and in dashboard..

Have you any Vag tacho, vag commander or Vag tool..????

If you have pincode could recode....EVEN WITH VAGCOM

But to be honest, something is wrong here.....

Does Ecu is ok now...???
This is you can diag???
If bad Ecu/checksum/file.... BAD the inmo flashes, as there are no response.

Did you tried Original flash again suposse???

Edc15 Vag for me safer way is fgtech in bench( if not possible car with charger)...

Never fails!!!

I remember now an EDC15 2.5 TDI A6 , this car has inmo sector in flash.

Could you please tell me reference number, for exact info.

Got it working again. Ive done lots of edc15 before and never seen somthing like this. It didnt start when i writed tuned file, it was done on original file and everything seemed right and checksum ok. Ecu didnt responce but when i kept trying i managed to write original back and it started again. Then i did it again, write tuned file and same thing, not starting and after few times it wasnt working even with original file :( Then i found original file from here with same hw/sw and writed it and it started again. WEIRD. Tryed Mpps, kess v2 and fgtech. Every tool writed it 100% with no error messages. I found out that kess v2 was best tool to recover it.

Flashed by obd, this ecu dont even have boot mode? i would do it on bench but couldnt find way to do it, now i need to get bdm frame if this happens again. Heard another same kind of story like mine. Audi a6 2.5tdi and immo freaked out, and they got it working with vagcommander/vagcom. I have only vagcom and didnt have the codes so couldnt try it.
