Vibrating sound from filler cap area
Standing next to the car while the engine was running I heard a noise suddenly appearing from the tank fill area. It lasted for some time and suddenly stopped. When it started the next time I opened the filler cap and the noise stopped. This probably has something to do with suction control of the vapor from the tank? Filler cap or some other valve clogged?

I'm guessing that there's a breather pipe somewhere that may be blocked. Someone will be along soon who knows more than me!
Just noticed the details of your two cars. We didn't get the TDi in the D2 in the UK and I've never seen a D2 W12. Have you posted photos?

I'm reading up on the details in Elsawin, but was hoping to get some feedback based on previous experience.
Pictures - well I haven't presented the cars anywhere on this forum, but I posted some pictures related to selection of tires for my new(secondhand) RH rims: http://forum.a8parts.co.uk/showpost....84&postcount=8 The W12 is black and the diesel is dark blue. Hard to see the difference sometimes. The diesel engine is the weakest(150 hp) option for D2 and the W12 is strongest(455 hp modified from 420). So I have both ends and actually enjoy both of them. The diesel is very economic and once you are on cruisecontrol you don't feel a big difference. The W12 is a totally different animal when not on CC  (produced only 700 something)btw the problem is with the W12.
