Afternoon,
I have just changed the fuel filter on my Golf mk4 TDI 150, it all went well and car started up no problem & drives fine, but now i have noticed a 'filling/woosh' sound when i turn the ignition on, also after turning the engine off there is a small squelch sound as if air/fuel is being trapped.
Any suggestions as to what it might be? The squelch sound sounds like its coming from the small black thing near the fuel filter where the fuel lines go into.
