[Bianko16]

Hi guys, I've a question:
today I ve read an edc16u1 on audi a3 2.0 tdi BKD with kess v2 by OBD..
-Reading perfect.
When i start To write after 20 second the kess say me that an error occured during writing... i retry in recovery mode but the problem still present and after this the car won't starts ad fan ON.
I dismounting the ECU and write via k-line on bench with the same tool and it write succesfull and car start whitout problem...

this is my first time with this car, what could have appened ? maybe error on CAN communication? Battery problem? (voltage 12.30v)

thanks but I wont to know the possible cause. :peaceful:

Maybe the fault is due to the tool? Clone? I had similar problem with can edc16c35 and i write in bench via kline without problem.

Yes, I had a similar issue on my Audi A3 but I sold my car with it. I even tried to find information on different services even on damn https://uk.edubirdie.com/ but without any success. Anyway, I bought another one.
