After reflashing all the same.. No foults in other modules.

Maybe you have damaged trabsistor in power stage, make a pricture with ecu and I will mark were to measure

[amigokola]

Reflashed it once again with VCP but it didnt do the job so maybe electronic is foulty or eeprom job ??

[ghitab]

Measure betwen 1,2,3 and V+ and gnd, if have short in one transistor then need to replace ecu.

[amigokola]

It has 3 shorted to GND and V+.

Measure betwen 1,2,3 and V+ and gnd, if have short in one transistor then need to replace ecu.

In this case other ecu.

Somebody knows if there is a way to change only electronic part from other car ??
I have some info that it can but didnt work in my case. Even after reflash and eep mod.

I did replace some and worked, try keep original ecu eep , some parameter inside eep used for sensor calibartion. Always connect supply voltage after secure ecu in place by screws.

I have had same problem, replaced ecu and everything ok, i want to try repair old one, find out where is transistor located and replace it with non shorted transistor. Have somebody tried it?
