car sometimes judders at low speeds (usually when in high gear). also, it dad have a strng smell of fuel coming from the boot area, but that has dissapeared. and now its idling funny when you start it. i know i really need a vag-com check, but can't afford it (and don't wanna pay vw 50 squids for them to plug a computer in my car). i have a limited warranty on the car, but don't wanna claim on it until i know what is exactly wrong (don't wanna replace the wrong part). here are the possibles (suggested so far)... -coilpack -fuel pump (believe theres 2 pumps - a lifter and a main?) -cam sensor here's the test i've done... -sprayed water on the coilpack at night, no sparks. -opened the hatch in the boot to look for leakin fuel, didn't remove anything (wasn't sure how to depressurise the fuel lines), but it was very dry down there. whats do people think? or does anyone live in berks and have vag-com that i can borrow?
