Gurgling noise

[danb]

A search found nothing....

The car was parked up today after a 10 mile drive and whilst cleaning the rear drivers side wheels I kept hearing this gurgling noise, kinda like a sink plug hole. This happens every few seconds and continued for about half an hour.

There is a little pipe just behind the rear drivers side wheel, not sure if this is anything to do with it???

I know its not the most exciting problem but it's a bit of a worrying noise

any ideas

I think it will be the petrol feed return. The electric petrol pump runs at a fixed speed and hence delivers a specific amount of fuel. That amount of fuel must be enough for the engine at full revs therefore most of the time it delivers to much full. There is a mechanism to deliver that full back to the petrol tank via a return pipe.

wouldnt take 1/2 hour to do that , if its 1.8t ur driving , its probably the water cooling for the turbo , nothing to worry about

I heard it to, its definatly not the turbo as its at the back of the car. I think it probably is the fuel returning to tank. Its seems to be most noticeable when the tank is full.

Heard that on mine the other day... and mines a sooty.

I presumed it was the A/C?

If other cars are doing it I wouldn't worry, the pipe is probably the fuel filler overflow that goes to a hole just below the filler neck.

Not too sure what this either, but I get it on mine as well.

First time I noticed it was just after getting home after filling up with petrol so I un-did the petrol filler cap and had a normal whoosh sound and then the gurgling stopped so I wasn't too worried about it anymore.

I don't know what the actual problem is, but I think it is just air working it's way out of the fuel system slowly.
