Dash voltage regulator..obc dim, gauges low

[ratty]

Hi everyone.

My 325 cab has very dim obc and the temperature gauge reads a little left of center.

I was told a while ago that it's a common problem due to a voltage regulator which is easily replaced....

Can anyone give me any hints as to where it is and what i'm looking for...or any other useful advice

Many thanks

E30's don't have a voltage regulator for the dash (not one you can replace anyway). The temp gauge reading left of centre sounds normal, so I should not worry about that.

When you say the OBC display is 'dim'. Do you mean that it's virtually unreadable and only visible in bright light, or that it's a bit dimmer than normal ?

If it's virtually unreadable, then it's probably the OBC backlights that have blown (common problem). These backlights are mounted in a white plastic housing that slides out from the side of the OBC. It's a bit tricky to gain access if you have never done it though.

You have two options on replacement:

1 - Go to the dealer and swap a crisp Ԛ£20 for a new backlight
2 - Replace the two 5 volt bulbs on the original for a few pence.

Cheers,

Ian.

Cheers Ian,

Yeah...the obc is virtually unreadable. Also the red light on the hideous Bmw alarm (deadlock thing) on the drivers door is so dim I cant tell if it's armed or not..

I thought it would all be related to a common low voltage or earth problem.

I'll investigate further.

Appreciate your help.

Nice 332i mate... looks a bit special that
