Right chaps.... I wonder if any of you have ever come across this problem?? I bought my 1999 Audi S3 about a month ago and since doing so it has been leaking petrol out of the back end! And when I say leaking I dont actually mean leaking I mean gushing out beyond belief. Took it to my local garage who i know very well and I told em to sort it if it was a quick fix but if not I'l take it back to the garage as it has a 3 month warranty. They said they cleaned out the breather pipes and that will probably sort the problem. I took it for a spin and later on that day the same thing happened, fortunately i was near to the garage so I took it straight there because the garage hadn't actually witnessed any type of fuel escaping and when they saw it they couldn't believe how much was actually coming out! And they also said they hadn't come across that before so they advised me to just take it back to where i bought it (luckily a dealer) and get them to sort it. Since taking it back the guy phoned me to ask whether ive had it chipped yet to which i hadnt. Then he phoned me later in the day to ask whether it was leaking petrol before i took it to my garage to have the breather pipes cleaned because he asked audi about the problem and they said they were baffled and the only thing they could think of was that the breather pipes were put back on the wrong way round, but it was leaking before hand so that wasn't the problem. And just to add... when i took it to the garage when it was actually pissing out one of the mechanics said a quick fix would be to loosen the petrol cap, i went round the corner and again it was pissing out the back end and out of the side of the car out of the petrol cap... much to my embarresment!!! I haven't heard back from the dealer again so I thought id see if anyone had ever heard of anything similar??!! Also any sympathy will be greatfully accepted! Also another thing to add, if i open my petrol cap too fast after driving the fuel will just fly out, i have to open it ever so slightly and let it slowly hiss out.
