I flashed a tuned file into a A6 Allroad 2.7 T 2003 using my MPPS read fine and write correctly. ECU is ME7.1.1 with 29f800 and 95p08

Started the car afterwards and drove for 10 minutes, Turned off and the car would not start again!

Disconnect the battery for 30 seconds, put back on and the car starts!

Thought it was the IMMO so off'd it, but still the same!

So Re-flashed the Original file back to the car and its Perfect with no problems.

File is good tuned file from a good tuner, MPPS is perfect as if it was a problem with that I would not beable to correctly re-flash ecu with ori file..

So whats the problem? Tuned file? MPPS? Immo??:giveup:

If its the cks then what is causing it?

Tuner is good and cks will be 100%... maybe its mpps?

make mpps the cks or is it done by your tuner ?

maybe you can test to make the ecu over debbuger .. or solder the chip. (if some change for readprotection)

100% checksum problem!

have seen this exact issue with mpps, double check the checksum and rewrite!

Good luck.

Did another me7.5 today on an Audi tt. Same thing happened. So reflashed ori back on and used galletto to flash it again and same problem so I know it's not the tools.

I have 2 files with the same problems . Will send to anyone genuine for help to see what is wrong
