1995 540i 140000 miles. Starting skipping or rough idle at start and idle, upon increase in speed the skip goes away, and then sometimes it stops at idle but not for long. Have had the gasket replaced 2 years ago that lets oil on the spark plugs (sorry, don't the correct term). Removed and replaced the spark plugs without sign of oil this time. Also had it put on the computer at BMW, nothing showed up. The check engine light flickers at times, does not stay on long enough to capture code. Any suggestions, could it be a vacuum leak? 2. Upon putting key in the ignition and turning, there is a whining noise in the engine that continues 5-10 mins. then stops. Thanks for any help you may have. |

Hey all- I have a 2000 528i- sp, pp, manual. Since it has gotten kind of cold here (in the 30's and 40's) I have noticed that the temp gauge never gets to the mid point unless the car sits for a long time. Once I start driving it drops to right above the quarter hash mark. I have had the car since its birth and it has always warmed up to the halfway mark and stayed there regardless of the outside temperature. IIs this a cause for concern? I'm taking a 200 mile road trip tomorrow and want to make sure this is not a problem. No check engine light or any other warning has come on. Thanks for your help.

Replying to: milner007 (Jan 22, 2008 6:38 pm) It's a failed thermostat, a very common problem for a 530i of that age. Make sure that you -or whoever does the job- replaces the plastic thermostat housing while you are at it. It's cheap insurance. I'm taking a 200 mile road trip tomorrow and want to make sure this is not a problem. It may run a tad rich, but you aren't going to damage your car. That said, I'd fix it at your earliest convenience. No check engine light or any other warning has come on. That's not unusual; when the thermostat on my 528i died it didn't activate the CEL either.

Replying to: Mr_Shiftright (Jan 23, 2008 10:09 am) I decided to take the advice of the Indie specialist that does my car and do a prophylactic replacement of the radiator and expansion tank. It's not that expensive and should help you enjoy your car for many more miles.
