Exhaust burbling like crazy!
« on: December 03, 2010, 12:11:24 pm »
Drove about 10miles this morning and parked up! Put it in Park and reved the engine a bit (as you do when you've been driving diesels for 4 years). The exhaust was burbling lots the revs drop... Is it just because it's cold??

Not even because of the cold. It's perfectly normal for it to sound like that.

I know that it burbles a little usually... but this wasnt like it is usually!

By saying "put it in park" i presume its DSG?  :signLOL: If so, its possible to catch the car out a little, as it goes qucikly from drive, passes through N and R to P. The gear box has different modes in each selection, either limiting torque, revs or both. For example, it shouldnt rev out to 8000 rpm in N only halfway, spooling up speed. As it revs up, it may simply have still thought it was in N or similar and cut your spark or retarded ignition to bring revs back. Its in N that mines burbles the most.
HTH  :happy2:
