Hi,

there was a thread once.....
Someone managed to swap a broken part inside the ecu to have the ecu working again.
I have a 032HN ecu without ignition / coil pack drivers.

Can someone remember the thread name or something?

Thanks, i have the ecu on my desk.

It looks fine from the inside. nothing burnt or something.
Will try to measure and compare the 30397 with another ecu.

regards

Try to check power diodes first? check that whole ECU, VCC line around ICs is energized. That ECU communicates with VCDS under diagnostic port?

Yes is can read/write with different tools, vcds works fine, no dts with ecu in the car. Only problem is that there is no ignition.
Tried different ecus and this ecu in different cars. I dont really know what to check next.
