I am trying to be able to flash my 01 Allroad via OBD. I have always had to bench the ecu because Nefmoto cannot seem to connect to the ecu in car. I have tried removing the cluster fuse #15 and still no result. The ecu in question has been flashed countless times on the bench.

I looked at the wiring diagram and the only things on the K line in this car are the cluster and ECU.

Any ideas?

try the 'ole dedicated K-line trick..direct from ECU to OBD port.

Everything is on the K-line.

Every. Thing.

I have never had an issue. Slow init, 38400 baud.

So, just try slowing it down? I never thought of that. I just always let it go auto. Will try that out.

I was thinking about my own K line just for flashing. Like installing a switch to deactivate the old line when I am programming.

I assumed you tried all the baud rate/inits, this is a last resort pretty much.

Well, flashed for the first time successfully. Ran 38kbps and it stopped twice, just clicked to reconnect and it continued where it left off. Never touched the key.

Think i will try even slower next time.
