Temp Gauge Fault

[expediant]

Hi,

Ihave an 318 si 1993 registered.

I recently had it in the body shop to have a new wing and front panel fitted and now notice that my temp gauge shoots straight to the half way point as soon as i switch the ignition on.

I am guessing that there has been some kind of wire or electrical damage done to the vehicle when the new front was being fitted.

Before i noticed this i also fitted a new cd player to the vehicle.

MY QUESTIONS?

Where is the temp sensor and Gauge sensor located on the E36 and what are there colours?

Sounds daft, but could i have done something while fitting the cd player.? (i simply did a cut for cut, wire to wire replacement so didnt really tamper to much)

ALSO, i am new to BMW's and although the fan seems to run constantly, it does not speed up as the engine gets hotter. should it? and is this to do with the gauge fault?

PLEASE HELP. THANKING YOU ALL IN ADVANCE.

this might be a stupid question... but sometimes my needle is at NOT *normal operating tempature* whithout being driven simply because of the tempature outside...
