Hi all

I have a 19 TDI PD 130 which has now done nearly 160000. I have recently been hearing a deep thumping or Whomping sound coming from the engine when on tickover. If I blip the throttle the sound normally goes away, there has been no performance loss but a fellow cabie has got a Galaxy with pretty much the same lump in it and his makes this sound most of the time which is driving him nuts. It almost sounds like a vacume is being created asthe noise is not mechanical. Any ideas?

Thanks for reading this

Cheers all

Weakened rubber hose collapsing perhaps.

Thanks for the reply Mannyo I will have a look at the hoses later today when the suns up lol I hope its somthing nice and simple like that.

I'd take a good look at the engine and try to localise the noise - where is it coming from exactly.

When you blip the throttle you get the EGR active - may be related to something hooked up to there perhaps?

Good luck with that one

I get this myself, although not as bad as what you describe, I too think it's a hose somewhere, I know the small on to the egr valve can rub a hole in itself, but I suspect the big one that goes to the front of the air filter box, although I've yet to find a split in it yet.
