intermittent gauge problem on my 95 m3 HELP!!

[My3rdBimmer]

Just got my 95 M3 yesterday... and i love it~!!!!

That being said, I bought it knowing it has been having an intermittant gauge cluster problem.. I also paid 1200 less than what they were asking becasue of it..

symptoms:
-the gauge cluster will cut out..

-all gauges will go to zero..

-the mileage indicator as well as all indicator (brakes check engine etc) lights will go out seemingly for no reason that i can reproduce.

-after a period of time everything will come back on..

-all the lights will flash and the dinger will ding jus like it would if you just turned the ignition on.. the car runs fine through all this....

-The dash illumination lights stay on (when the headlights are on ) like they should..

-it just seems to effect the instrumentation.

the longer i drive the less it happens it seems....


This car was meticulously maintained by the dealership..every oil change and service done... and only had 64,000 miles on it just had its inspection 2 and the dealership replace the ignitionswitch thinking it would correct the problem.. the owner decided to buy a new M5 and did not want to put any more money into the problem.

the only gauge related problem i can see in this thing's history is hat the fuel sending units were changed out in 97.

i am a pretty good mechanic with a little below average electrical and electronic skills so i defer to you experts out there.. is any on else having or have had this problem

thank you in advance for your help..

This would be just a guess but it could be either your speed sensor located within you limited slip differential, or possibly the wires that run to your gauges that give your speed information. Both seem highly unlikely in the first place.

it seems my wires are effected too.. when the gauges go off so do the wipers...

Bad grounding?

[saltshaker185]

id get some contact cleaner and clean the gauge contacts on the back of the cluster... also im kinda leaning towards bad grounding also... check to make sure none of your ground wires are pinched or loose under the dash below the steering wheel... if neither of these work then i would give it a shot at replacing the ground wires but this is a pretty big job because there are alot of wires but get yourself a spool and find sometime and its not too bad a trip.
