Hello,

I 've recently purchased 1997 328i (with 89k miles on it)
The digital clock on the OBC doesn't work (it doesn't light up at all).
My car has the 18 button OBC. All other functions on OBC seems
to work fine.

Has anyone else have (or has had) similar problem?
If the problem is with the light bulb behind the clock, do we
need to disconnect the battery before unplugging OBC?
I don't have the radio code, so I don't want to disconnect
the battery. I will have to figure out what to do if I ever need
to replace the battery.

FYI, so far (within the last few months), I have replaced the following:
- Brake Light Switch,
- Water Pump (with a metallic impellar)
- Fan Blade (plastic fan behind the radiator) - it broke while driving
- Multi Rib Belt
- Hood Strut
- I am about to put the secondary air pump, control vavle, new spark plugs.
(and Fuel Filter, and the transmission filter & fluid change)

Anything else you guys can think of as preventivive maintenance ?

Here is the picture of the car:

no need to unplug the battery.
reach in the sunglass holder area and feel around for a hole on the bottom of the obc.
push up on it and pull out (sometime it gets hung up )
the bulbs are right there it will be the last one on the right

You also might want to replace the oxygen sensor in about 10k miles. If you see a drop in mpg, it'll probably be it.

Thank you guys Dan, Vance, andreyiv !!!
I will replace the bulb in the OBC this weekend; also, I will
plan on replacing the oxygen sensor(s).

For some reason the picture (of the car) attachment
on this board doesn't seem to work for me....

Question might sound dumb but i have the same clock problem. i took the bulb out (thanks everyone for the tip) and it seems like a special bulb to me, can this be found anywhere or is it something you have to order from a bmw part specialist ? thx again for this great board
