M3.8.3 Problem flashing with MPPS.

[JimCoupeTQ]

Hi, I bought a 06A 906 018CJ ECU wich is supposed to be M3.8.3 wich should be flashable. The Flash chip is 29F200AB But with MPPS i cant write to it. Im just getting MPPS error.. My tool works for other ECU like Me7.x.x and so on.. I know it works in those cases.

Could this 29F200AB chip be a non flashable chip?...

try this way and have fun

Thanks i have connected as described in "Bench Flash".. I can Get ID from ECU but not flash. Maybe i have to do an Immo OFF before?

I get ERROR message. ECU programming Voltage Missing.. But hmm..

dissolder flash and do it on banc with other programator. some of this ecu cant read ore write.

you are missing +12v on pin 43 on the ecu

you are missing +12v on pin 43 on the ecu

I have the Famous pin43 connected to +12V an i have double checked all connectors with multimeter. I have 12.5V from a bench battery connected to a stabilized source.

Im starting to think that it might be the immo? Security Access?

@jolidj This is not the PLCC44 chip its the 29F200AB chip.. Ive read tons of threads where ppl make this work? OR have i been disinformed,, hmm..

I flashed exactly this ECU - 06A 906 018CJ on friday. Immo is not the issue.

Thanks.. Saved me some headace.. ECU Programming Voltage Missing is still my problem.. any suggestions?

i flashed many of these ecu's .. programming voltage missing is always pin 43 never had problems with immo
