Australian Car Repair Issues? Ask an Auto Mechanic for Answers ASAP
I would say you have a oil pressure gauge sensor with a ruptured diaphragm.
If it just happened, it doesn't take much to make a mess of oil.
I would suggest towing the vehicle to avoid making more mess.
It won't be too bad if that is the cause.
I would say about $250, including clean up etc.
Do you need any further help?
I hope my advice has been of assistance to you.
How did you go with your problem?
