Anyone know what the little bar of lights (green to yellow to red) on a 90 325i would be stuck on yellow and red? T belt, waterpump and headgasket where replaced and oil changed...light won't go off...tried running codes, nothing..

Any ideas?

Thanks

That light is a gimic.
After so many miles that service light comes on and is time
to take to a certified bmw machanic that changes the oil
then resets the idiot light with a tool for the next change.

You can reset the bar at home with just a paper-clip or
speaker-wire..

Or if you have the money and want to be fancy you can
buy the tool (does the same thing as the paper-clip)

That bar isn't a senser, it's just a reminder light :)
Here's a link that tells you alittle more about it.

If the service/oil bar turns red/orange again after a day that means your S.I bettery is dead and will need to be replaced, but that's for another thread :)

no no! I'm very new when it comes to the inline 6's with these E30's. I come from a VW background, and the electronics on the E30's are a little more complicated then I had anticipated.

I'm actually looking into purchasing this particular car...(90 325i with 206K)

timing belt, headgasket, waterpump, rear diff seal, tranny has all been replaced or rebuilt.

I held back on putting a deposit on this car tonight due to a couple things.

1- that light bothered me.
2-slight whinning or whirring from rear. (not sure if it was the diff. or bearing etc etc)
3-slight rust

at least one of the main probs are somewhat solves:)

Thanks again
Ryan

(still not clear on the "S.I" battery still)

1 - Any good BMW mechanic can easily do that for you for free while you get the saftey done (if not than you should get a new mechanic).

2 - Check the fluid level on the differential, check if the hanger bearing on the drive shaft is worn, and check the guibo (the rubber flex disc that connects the transmission to the drive shaft) for cracks.

3 - Take the car for an extra half of a day and bring it to a good bodyshop that has worked on E30's...they will be able to tell you if the car has been hit or the rust is really bad. While at the body shop get them to take a good look at the floors! It is a typical rust spot for these cars.

Awesome info thanks:)
how exactly can I check the fluid level on the differential?
I was told on ANOTHER e30 I was checking that it DOES need a new guibo...the part supposedly runs for roughly ~$90...what kind of labour are we looking at for the install?

1234-thanks for the link:) very helpfull, answers alot od Q's

Undo the top plug (fill-plug) on the cover, then stick your finger down it.
If you can't feel any fluid, it needs to be filled

Not real high tech, but that's how it's done. lol.

A quibo is pretty cheap...call around (even the dealership). It is probably about 1 hour to swap out the guibo (you have to drop the exhaust to get at the driveshaft).

Awesome thanks guys!

...maybe I'll take a good 2nd look at the e30 I checked over this evening.

Also- if you know of any e30 325 in Ontario\Quebec lemme know.

I've checked out about 5 so far...they're either REALLY good...or REALLY sketchy.

(I'm hoping to check out that 2dr 325i in burlington from the classifieds..if it's still available)

thanks again:)

I know these guys covered the problem areas it could be, but if you're used to FWD Dubs, the sound of the older BMW rear end could seem alarming. Since new they make a whirring sound from back there. Try to get another opinion from someone experienced with Bimmers, although it wouldn't hurt to check up under there anyways. Just letting you know that it could be normal.
