Hop in the car, put in neutral, push in clutch and turn key. Nothing. Actually the noises of all the system interlocks clicking around me, but no starter action. Release clutch and push in again and the car starts. What I just described happens 90% of the time. I always have to release the clutch and then push it back in a second time and the car starts. The other 10% of the time it does not start on the second cycling of the clutch pedal, rather it may take three, four, five, six clutch pedal in and out cycles before the car electrifies the starter motor.

Is it the clutch sensor or is it the ECU not recognizing the key and if it were the ECU/key thing, why then do all the interlocks and other actions take place? Battery is good. Car starts easily when it does decide to start and life is good. I've searched these terms quite a bit and while not getting an exact replay of my issue, those with the closest similar experience seem to say the clutch sensor is the fickle actor. My car is a 2004 330Ci convertible ZHP. Anyone experience a similar clutch in, clutch out, clutch in again then start?
