I have a couple of questions about my 89 325i.

1. How hard is it to change the timing chain/belt. Can anyone perhaps reference me to a tech article about this process.

2. My tachometer and temperature gauge suddenly stopped working. Does anyone have any idea why this might have happened?

3. The warning light for my brakes won't turn off. I just put new brakes and rotors on the car.

4. The warning light for my brake lights wont shut off even though the lights are working fine.

Any help anyone could offer would be greatly appreciated. Thank You in advance.

Well, here we go:
1.) Timing belt-If you are mechanically inclined (or know someone who is), and would enjoy spending 8 hours under the hood, then the timing belt should be no problem. When you do it, make sure you buy the tensioner and water pump as well, for those are all right near it. If you get the belt done at a shop, then it'll be like, 400-500 USD. I just did my timing belt with my Dad, and it isn't that hard. But make sure you have a Bentley manual or a good guide before you undergo the procedure. I can give you a good guide to doing it.

2.) Check some of the fuses for the tach and temp guage. Look on the instrument cluster, as well.

3.) You forgot to get the little fuse wire indicator thing that goes on the LF and RR brakes that turns off that wire. The wire rides on the brakes, and when it breaks open, it completes the circuit and the light comes on.

4.) Check your third tailight. If that works, then it's the bulb in the third tailight. Make sure you get the OEM spec bulbs, rather than a cheap brand. Otherwise, the light will stay on.

I hope all this helps! If you have any other questions, feel free to ask!


Three rocker arms later and I still haven't learned my lesson!
