Question about Cars & Trucks
My gas gauge has not worked for years. Now my speedometer is jumping around and the oil pressure gauge will peg and then come back to normal. Do I need to fix something with the instrument cluster?
The fuel gauge will be the tank sender unit fault--- The speedo will be the sender unit on the gear box playing up and the oil gauge will be a fault to the oil sender unit. The only common point is the earth which may be loose rusted

have you got a dimmer switch on your model to dim the dash lights. if you have it may be faulty. link the cables together if the lights work the switch is faulty. if you have not got a dimmer switch
your printed circuit on the back of the dash may be faulty or the plug in the back of the dash is not pushed all the way in. hope this helps

Common problem on BMW's apparently...there are on-line repair services but they are NOT cheap...100-300 bucks. Tough to fix yourself...unles you are a highly skilled techie!

I had the same problem with a car i owned and found out it was a short in the wireing in the dash, you will have too have it re-wired, but too be certain you should have it checked out by a mechanic in your city.........

IF YOU REMOVE INSTRUMENT CLUSTER AND UNPLUG IT,PLUG IT BACK IN AND UNPLUG IT AGAIN..DO THIS A FEW TIMES..IT SHOULD CLEAN OFF SLIGHT OXIDATION ON CONNECTOR TERMINALS..HAVE SEEN THIS BEFORE..I ALSO THINK REPAIR CONNECTORS AVAILABLE FROM DEALER

SOURCE: oil pressure gauge pegged at120
Your gage is electronic I take it, buy or borrow a regular gauge and test it again. If the pressure is indeed 120PSI your oil filter is about to blow the cover off itself. This issue is most often caused by a stuck pressure relief valve on the oil pump. And indicates replacement is necessary.
