As you are probably aware there are a set of fuel tank breather pipes in the passenger rear pillar, and another that runs along above the drivers head to the front of the car for the anti pollution gear. These pipes carry fumes via a canister on the rear of the fuel tank, it looks like a little fuel tank. If the pipes break then when the tank is full, the high concentration of fumes will cause a fuel smell in the car. I had the pipe that passes over the drivers head break, and the resultant pong nearly caused me to pass out!
Check the breather pipes for breaks, and also check that the rubber bit ( technical term) between the filler and the tank is still OK and not leaking.
Hope this helps you!
Cheers

I also get fumes if the tank is more than 1/2 full (2200TC) in the boot & the cabin. You can also smell petrol at any time if you drive with the window open. No sign of dampness anywhere though.
I'm aware of the breather pipes in both the rear pillars but not of an overhead pipe or a canister which I've never noticed when looking at the tank. Is this pollution control only on the export models, Guy? I've tightened the filler pipe as much as it will bear & replaced the o-ring on the filler orifice which cured this problem on my P5 but it hasn't helped the P6. I'm assuming I will have to have the tank re-conditioned at the moment. Any other thoughts from other members?

I had a petrol smell in the car for 6 months before I found the problem - tried everything (almost).
I decided to get serious about the vapour breather pipes behind the panel above the wheel arch. In fact, I removed the rear wing so that I see if I had a blocked or broken pipe.
Here's what solved it.
The plastic pipe exits the boot area inside a rubber grommet protecting the pipe from rubbing on the rough metal of the hole. The grommet had perished and the plastic pipe had rubbed itself a hole on the unprotected metal hole. The fumes where able to flow back into the boot, behind the painted metal panel, and into the cabin through a hole I found behind the back seat high up near where the rear glass and the metal bulkhead meet.
I filled the hole with metal epoxy glue being careful not to cut off the fume flow, cut a slot in a new rubber grommet, fitted the grommet over the pipe with slot side up, squirted black silicone sealant in that area. I also filled the gap I found behind the rear seat.
I haven't had the fume smell since and it's been over a year.
There are other causes of a fume smell but that was my experience.

Thanks for that!
I'll have a good look at the breather pipes before I remove the tank, including removing the rear wings as I want to underseal them anyway.
