evening all just a quick question ! when the car my car when driven hard i get a small vague smell of fuel but when its driven normal theres no sign of any smell what so ever ! any help would be good thanks alot and hope to be of some use to everbody else sometime !!!

I presume you mean inside the car? If so, then you might have a breather pipe on the engine starting to crack and its coming through the air con

How is the usual Y pipe on top of the rocker?

very easy to replace and seems like a common problem arent to expensive from skoda either
