United-Kingdom Oil light flashing

I picked up my 02 reg MCS on friday and noticed whilst driving home the oil light was flashing intermittently, it only seems to do this when the engine is warm, it sometimes does it when the pedal is depressed or just when ever . there seems to be no other particular time it occurs other than these. i have checked the oil and all seems well. i had it to the dealer this morning and he has got it booked in tomorrrow for a rocker cover and gasket as he said there was a slight leak on it. could this be the problem for the oil light as i was under the impression the oil pressure under there was very low and therefore would not have an affect on the oil light. They never checked the oil sensor or the oil pressure output from the pump.

if any one can shed any light on this matter it would be greatly appreciated as i can get back to enjoying my new car asap without the worry of the oil light snag!!! cheers team!!

There is no fan belt - sometimes the quality of advice on here is poor to say the least..

Have them check the Oil Pressure and the Oil Pump - I have known of the odd and rare oil pump failure, the end result does not need thinking about.

Oil pump repair is fairly cheap.

Did you buy the car from MINI with warranty or have you bought it elsewhere??

United-Kingdom still flashing!!

had my MCS back to the dealers today for them to try and fix the oil light flashing, they thort it was caused by a slight oil leak on the rocker cover, they changed this to stem the leak, this has stopped the leak however not the oil light! they checked the oil pressure and all seems well as does the level etc... there were no faults registered on the system when plugged into the diagnostics computer for oil pressure so this is surely an electrical fault somewhere?? however all the symptoms remain as before, only occurs when warm etc..
has any one had this happen as its already growing old!!??
again any idieas at all are much appreciated!
cheers.

Just make sure you keep the paperwork to show it was checked.

Yes keep a record / written evidence from the dealer that despite your 'oil pressure' warning light coming on, your oil pump is working properly. If this fails you can be looking at a bill running into thousands. If this fails, and the dealer failed to spot the problem, you could hold them liable for the cost.

I had a flickering oil light problem when my car ('03 S) was new, shortly after taking delivery. It turned out to be chafing of the sensor wire against the exhaust heat shield, wearing away the insulation and causing an intermittent short. The dealer fixed it by wrapping the wire in a protective sheath and securing it away from the heat shield. So I would suggest a visual inspection of your sensor wiring throughout its length. And given the age of your car, you should also have someone test the actual pressure put out by the oil pump to see if it is within specifications. Good luck.

I had thisproblem too. Started as a very intermittant quick on/off oil light flash. Took the car in twice but oil was fine. Eventually developed rattle sound from engine. Turned out to be the timing belt on its way out!
