#1519 of 2734 1998 528i - coolant temperature fluctuations!!
Nov 22, 2005 (12:07 pm)
We just got a used 1998 528i with 70k miles on it. The car runs great. It has one problem - and i dont know if it is a big one. The coolant temperature needle just keeps fluctuating on some days - from the mid to the red zone and back and back to red zone again. And, on some days its just fine and dandy at the mid zone. Have checked the coolant level and everything there looks good. It has actually become a very irritating problem and we have scheduled an appointment at the local BMW dealer ( i would hate to go to the dealer though). We are skeptical to even drive the car with these temp fluctuations issues happening.
Any ideas on whats going on...please provide me feedback. is the engine really heating up as shown by the coolant temp needle or is it an electrical issue with the thermostat. Any feedback/sharing of similar experiences will be appreciated.

There have been a few mentions of thermostats on these forums among BMW owners... Do a search on message text for "thermostat BMW" and you'll find a bunch of hits.

My 1998 528i is having a similar issue but to add if my headlights are on at this time my brake lights also go on.
Let me know what you find.

That's odd, temp gauges in most cars now are glorified idiot lights in that they use "piezometric" circuits that cause them to point straight to the midrange if they are anywhere within normal range.
BMW is no exception (in fact the E90 has no temp gauge!). I have the same car and the gauge once warmed up never budges from the middle even on really hot days.
I'm guessing it's an electrical short or
ground problem in the gauge or the sensor but have it checked out, it's not normal.

52k miles and this "snapping" noise in roof occurs over road joints/bumps, etc. above my head between sunroof and door edge of roof. Anyone have this problem?
Also, a few light "pixels" going out in message area of instrument panel. Dealer said could replace whole panel for about $700.00. Any other suggestions out there? Thanks.

BMW NA has been picking up the cost of the display; you should only have to pay for the labor.

The passenger seat in my 2003 E-39 rocks slightly from front to rear. While I had the car in for service, I asked the dealer to take a look at it. He confirms that it rocks, but that there does not appear to be any problem with the seat mounts. He went so far as to go out on the lot and sit in 3 other E-39s and, guess what, the seats in all of them rocked. He has offered to order a new seat and have it installed. It’s enough of an annoyance that I’m thinking about saying “yes” to the offer. I did ask him to check with BMW to see if there is a solution that the dealership doesn’t know about. Does anyone have any ideas or recommendations?

Neither my 02 530i with comfort seats nor the 03 M5 sports seats rock in any way. I'd say definitely have the seat mount and the seat checked out.

Hello everyone. I am have 1998 528 and about 8 months ago, my keyless entry function stopped working. Does anyone know why and how to go about fixing it? My brother changed the battery but still does not work. Help. Thank you.
#1528 of 2734 5 series suspension
Dec 01, 2005 (9:15 pm)
Good day all,
Looking at a '99 528iT that has 77K, but looks in good condition. I've heard that the suspension on the 5 series had some problems due to its number of parts(too many), but was corrected around '99, '00, or around there. Does anyone know about the suspension getting loose because it has too many parts? I appreciate the advice. Cheers, Andrew
