Z4 Rough Idle for 10 seconds when starting

We've owned a 2007 Z4 3.0i for a little over a month now. I've consistently noticed a rough idle for about 10-15 seconds when starting after the car has been sitting (either over night or after several hours of cool down). Sometimes I hear a vibration, but no knocking as described for some N52's. I do hear the fuel injector solonoids tapping, but that's normal. We run 92/93 octane always. 35,000 miles on the clock ..read more

When starting the car at cold start, there is a rough idle happening and after the engine have warmed up the idle does move but very little. I have replaced: air filter, oil, Sparks plugs, and coil packs. Not sure what to check next. I also unplugged the MAF to see if the car runs better but it runs worse with the MAF unplugged. see attached link for video of issue. iCloud Photos - Apple iCloud View, organize, and share photos and videos with iCloud Photos on the web.

I started out with replacing my expansion tank (hairline crack in it) and now for some unknown reason the engine overheats because the fan refuses to run (just started it a few days ago! There seems to be 14+ volts getting to the fan connection but it sits still even when I near red-lining the coolant. The fan spins freely if moved by hand so it isn't seized. Is there a separate fuse for it? Maybe my meter was in errant when I checked voltage at connection. This has been a very long... electronic coolant fan ..read more

Picked up a project for $1k

Making my way over from the 7 forums. Couldn’t resist the deal. 2007. 70k miles. Manual. Sat for 5~ years under a tarp, so paint is trashed. It was a theft recovery, but clean title. EWS was bypassed, but still in the car. There was actually 2 EWS modules floating around in the car. Somebody must have tried to fix it - but the starter was dead. Dumped all fluids. Replaced starter. Got a key from BMW, replaced ignition switch and it started right up. Needs cleaning, paint and bit of body... Picked up a project for $1k ..read more
