I have an 01 S4 and am in dire need of a new ecu. I currently have an H ecu that has failed and have found an M with matching numbers. Is it possible to get this ecu and put it in my car without any flashing or adjustments? Just plug n go...

 

yes it will work.. you may set an instrument cluster code, but as long as transmissions are the same, as well as esp, abs and all that stuff you should be okay...

 

That's what I heard when me ecu died a few months ago. It should work.
