My car lost all oil pressure what might it be the dealer changed the oil sensor and its still messed up now my car started to shake and hum real loud what might it be?please post a reply if you have had similar problems. Series 1 supercharged

This all started AFTER the dealer changed your oil PRESSURE or LEVEL (which one) sensor?

It was my oil pressurethat dropped so they replaced the sensor, but it was still acting up.

If the oil pressure dropped, did they test it with an external gauge (not the one in the dash)? If that reads low too I would guess your oil pump may be shot. That would also explain the rough running (car running without lubrication).

Your car is shaking and humming really loudly, and it just started doing that??

dont wait to long i did and i am now buying truewildmans bonnie believe me
