Dripping noise after a spirited drive.

[!tf]

Evening ladies and gentlemen.  Just filled up the GTI and took her for a good old drive with a friend  Pulled up after a while and noticed a constant deep dripping noise from the fuel tank,  with the engine turned off. Any ideas what it could be?

Just unused fuel returning to the tank i would imagine

I thought it was that but It carried in for the thirty minutes wwe were pulled up .

As above, should be just the fuel return.

Mine does that too, even if I haven't been pushing it particulary hard!
Hasn't blown up yet!!

Maybe the sound of the exhaust pipework cooling down? The '32 makes a lot of 'ting...tingtingting..ting' noises after a blast

Fuel return . Didn't notice mine until about 3 weeks after the air went on.

I get this. When i open the fuel cap the pressure releases and noise stops.

Same on mine today. Any solution? It stoped after open the fuel tank cap and I hear a aspiration noise during a second.

It can be the canister?

To resurrect…

My car is doing exactly this. I understand the logic of fuel return and how fuel systems work… but I have never owned a car that makes this much noise and it would surprise me if VW designed them that way.

Is there a vent or something somewhere that could be blocked? So the bubbling noise is air going up the return line or something like that?

I replaced the canister for an ORIGINAL VW part and still have the same noise, it seems that it's easier to notice that once the ambient temp is higher.
