Gurgling sound from rear of drivers side

Sometimes in my GTi after stopping I can hear a gurgling sound coming from the rear of the drivers side. It can last from anything from 5 min to an hour (maybe more).

To describe the sound further its like a hamster water bottle constantly emptying, glug , glug , glug about 2-3 seconds in between each glug.

Does anyone know what this might be ?

cheers mikemod,

sounds like mine, when the tank is more full and in warmer weather. Didn't get it on my mkiv though.

Be intrested to know if other have it too or if some cars are exempt from this problem, maybe ours are just more hungry grin.gif

Keep an ear open RedRobin let us know if you hear it.

I think the gurgling noise is cause by the pressure diference in the fuel tank compared to the atmopshere. Think along the following principle, you have a bottle of washing up liquid, hold upside down and squeeze loads out, the size of the bottle decreases as you squeeze, it then grows back to its original shape when you turn it upside down, because the air has replaced the liquid. The gurgling is causes by a vaccum created inside the tank, because the tank is too strong to deform, it causes low pressure inside as the fuel has been used by the engine and air is trying to occupy the space. I have had this gurgling and loosened the cap, woooooooooooosh, air enters the tank, atmposheric pressure restored, no more noise. Nothing to worry about. Hope this explanation makes sense.

As reported: No petrol-gargling from me so far but will report if so.

A fuel filling sort-of-related quezzie:

Does anyone else have a problem getting their petrol pump nozzle into the neck of the GTI's fuel filler? The ribbed rubber keeps getting in the way....Any known techniques? Talk about protection!!

I have to force entry every time! I'm waiting for some other motorist to report me for indecent interference and get me arrested!! sekret.gif

With your throbbing Red GTi you can't get you nossle in becasue of the ribbed rubber, then you ask for techinques UHOH7.GIF

I have experienced this but only when streching it across the car becasue I have parked at a pump on the wrong side. But at least it stops the dirty diesel pumps from penetration , I don't want any FTD's.
