	ME 7.5 After flash with mpps car runsfine but not able to flash anymore? (FIXED) « on: October 31, 2023, 04:02:52 PM »

Hey guys,

i have a problem, so i flash my car several times with mpps but after my last flash im not able to write via obd anymore.

mpps says ecu not found, read id also not work.
i can log the car with vcds and i have no DTCs.

so what went wrong? the only diffrent i made is to put a new clutch in it so i thinks this can not cause the problem.

i try to remove the dashfuse -> not working
checked the harness -> all ok

checksum is ok

Yesterday I was able to flash and all was good.

But today : ecu not found.

When I flash or read ecu Id I hear my original vw amplifier in the rear making ticking noise.
I unplucked it but it makes no different to get connections to ecu.

What the hell is going on this car.
