Hi,

Had my car serviced 3 months ago by local VAG specialist, who replaced all the filters. I have just changed the oil myself and noticed there is diesel lying on top of the fuel filter housing. I assume the PD's filters are different from non PD's. Looking at mine, it looks like the filter screws onto the bottom of what looks like a cooling housing with a hole in the top and a recessed bolt. It is this hole which is filled with diesel. I dryed it up with a cloth yesterday and have recheked it today only to find more diesel lying there. Has anybody else experienced this? could be the filter/bolt hasn't been tightened properly, or something worse.

Any help would be greatly appreciated.

Chris
