Hi, I have a 2005 A3 Quattro 2.0TDI (140bhp) Recently I've found the car is having problems starting. It starts eventually after turning over for about 5 times as long as normal although when it does start it's quite noisy until I rev it through. It's done this about three times now and after the first time I had it in a garage and had the plugs changed on their advice although this doesn't seem to have worked. When the car is on tick over (I.e. at lights) the revs range from 800 to 1000. When at 1000 there is a slight vibration throughout the car. Also when I accelerate vigorously there is a little smoke out of the exhaust, not terrible but certainly not the norm. The car has done 120k miles and I had the timing belt and dual mass done at 80k. I went through a stage of having a problem with the turbo hose coming loose but after a few attempts at getting it sorted it doesn't seem t be an issue now, not sure if this is relevant. I am female so please don't get too technical but I know the basics so any advice would be greatly appreciated. Thanks in advance.
