Could be coming from gasket between the oil filter housing and the engine.
Best would be to take off the covers under the engine, give the engine a good clean so that you can see where the oil is leaking from.
Seriousness depends on how much it is leaking, just be sure to check the lever regularly.

Well i noticed it yesterday... so iv sent it in to Cedar, so I know im in good hands, guess il just have to wait and see what the out come is.
Also does Castrol fully synthetic oil make a difference to normal oil... or do you perhaps know what the best oil for my car would be?

318 2002 = N42 motor.
I had one too. Common oil leaks occur from the solenoids that 'plug' into the front of the motor. Sorry I'm a noob, no other way to explain it. You have to take the cover off and you'll see it. The seals just have to be replaced. There was another thread with this.
Another possible cause is the Vacuum pump is leaking oil. This can be opened up and sealed properly as well.
If BMW couldn't diagnose then doubt it's the gasket...then again they can be a bunch of idiots at times.
But Sankekur is right, a thorough clean will be needed then drive for about 50-100km and see where the oil is coming from.

No they should have as they picked up mine when it was sent in for the same thing. I just had oil leaking from 3 places simultaneously :thumbdo:
But just ask them to check solenoid valve seals as well as vacuum pump. Both are towards the right of the car and you said the leak was closer to that side.

We had similar on our 2004 318i Auto.. went in to the dealer 5 times to fix it.. replaced a whole bunch of parts untill they "fixed" it... found out from the guy who sold the car for us that the new owner complained about a oil leak & the dealer now says its a different oil leak so they not paying for the repair...

Bud don't always take dealer's word for it. They only replace and not repair when in fact some parts can be repaired. So maybe ask them to mail you a list of parts that need to be replaced. Post it here and maybe the guys can help you out and tell you what can be repaired or where you can source a part privately. If the dealer is charging over 10k, it's likely it can be done privately for half that.
