Hi

I've got a Mini cooper s 2009 1.6 turbo, with a whining noise when revved up from the lower front of the engine.

The noise sounds exactly like an auxiliary belt pulley / alternator whine.

I removed the drive belt and the noise is still there.

The noise is coming from the inside the sump !

Going to remove the sump and inspect the timing chain etc, but I'm not sure I'm going to see anything.

Anyone had any dealings with this engine or suggestions?

Thanks

Joe

I am no expert on these,but I believe these have an "on demand" oil pump.Looks interesting.

We have had a few of these, all with fairly high mileage.

All have had wining symptoms like you describe.
Serviced several times & had no running issues of which i would take it as a charateristic of the vehicle.

Although i cannot know how severe your symptoms are!
