Anybody ever repaired one of these things? Hans and Franz have figured out mine is fragged, as the car runs with an ECU from their 5-series sparts car but starts but will die under any load with my ECU.
They say they've seen this before with a 7 series of similar vintage and deduced somehow it was the airflow metering circuit.
Absent any bloack burned out parts I'm tempted to go down there, grab my ECU and resolder every joint.
Anybody played with these ever?
