Hello Z4 community,
I'm writing to try and find a solution to an issue I've been experiencing seasonally with my Z4. If anyone could maybe help me with a solution (or at least a step-by-step troubleshoot) I'd be grateful.
Just for reference, it's a Z4 2007 Roadster, specifically the M 2.0i and it's stock other than KandN air filter, rims / exhaust.
Whenever I'd go to crank to key the starting motor would make it's noise but not actually start the engine. The battery seems to be in good order as the electronics do work. But since I've drained the battery so significantly the tire pressure / steering would go out afterwards.
This does happens every 3-4 weeks also, so it's extremely consistent. This actually happens after I have a fair drive (and subsequently a hot engine), so my initial thought was maybe this was a crankshaft position sensor issue where it's cracked and the change in temp creates too much noise for the sensor to recognize the starting motor thus providing any spark.
If anyone had any other contributing ideas to why this may of happened I'd be happy to hear. Thanks for reading anyways.
