Sorry its taken so long to get back to you all, been loaded down at work...but.....Ive got the oil leak sorted! After taking the car to the local BMW dealership they told me it was the upper pan gasket, as was suspected by someone (see above), they also told me it would be serious money to fix it! Well, I took it to a nearby specialist and they told me that it wasnt the pan gasket, and it just looked like it was........they said it was the oil filter housing that was bad. I booked it in with them and kept my fingers crossed....and it turned out that one of the "O" rings in the filter housing was gone, and that the filter housing to block gasket was seeping. £140.00 to have all the gaskets and "O" rings replaced along with a full oil/filter change........well, I think that was cheap!?
The cars runing like new.....or it was, till last night when it died in the carpark at work. It had me completely stumped so I phoned the AA (arrived in under 10 mins!!!!) and it turns out the ignition switch has gone..........grrrrr!!!!!! The AA guy put a jumper wire over teh ignition switch effectively hot wiring the car, and it ran fine all the way home. Im off to get a replacement switch tomorrow.....got no idea though how to get at the wiring plug thats half way up the steering colum, that'll be fun!
