Hi Guys,
I am at a bit of a loss here. Not sure if we've had a freak accident or what really but I will explained what has happened.
EDC17CP14 Audi A3 2009. ID and Read the file using genuine Ktag service mode, file was then modified with a simple power tune + EGR/DPF off using a switech solution which have used plenty times before.
Written back on and the car won't start, then initially error codes coming up either P1603 "ECU error" or P160A depending on which scanner used. Also intermittently have seen errors relating to injectors when trying to turnover for a while.
Where it gets really strange is if I write the original backup back on the car still won't start, as if something has been lost in the process... my initial thought was immo issue but even after trying an immodelete same issues.
Things we have tried so far:
-Immo delete file
-Reflashing original file on service mode ktag
-Reflashing original file on using Boot Mode (Protocol P151) ktag
-Flashing original file onto the ecu on Ktag and then using genuine Kess with a standard VR file from Alientech DB on OBD...
-Flash original on service mode, then backup with BDM, then reflash with BDM.
-Same as above but also with modified DPF/EGR file.
Nothing seems to be working, ECU communication is fine I can read codes, I can even read and write and ID via OBD when ecu fitted to car but for whatever reason I cannot get it to start. This was supposed to be a pretty straight forward job and has now turned into a multi day nightmare especially over weekend when alientech support was closed.
Yes we have alientech support, they have reviewed the logs and can't seem to find anything wrong with any of the files. BUT in my experience the experts on forums like this know what they are talking about more than Alientech... also they are not open evening or weekends which just makes it worse.
Any suggestions please??
I've attached a couple of the files:
Backup - Original file read with Ktag servicemode
Backupimmo - Modified file with immo delete
BDMBackup - Backup read taken from BDM after writing original back on in SM
VR Ori - VR file for OBD map data.
