Hi all,

Golf Mk5 TDI SE (105 bhp)

I have oil coming out the top of my filler cap, I have replaced the filler cap with genuine VW cap, although its better, its still leaking.


I have searched the forums and internet and it not uncommon, and there is talk of a CCV (or something?) being blocked and to check that, but i have no idea what im looking for.

Im going to put another seal on, but im worried there is possibly excess pressure not being released?

Any help appreciated

Thanks
