hi all, i don't really know my way round an engine that well apart from the basics so any advice will be great! its a 2004 model and well looked after,regularly serviced and has covered 60,000 miles but im having a few problems, problem 1)basically more often than not it takes 2-3 turns of the key to get it started, problem 2) between 2000-4000 rpm it sounds like its pinking (fuel igniting too early im told) and not feeling as smooth as it should? so i had it put on a diagnostic and it said something about INDUCTION DOORS MALFUNCTION??
Last but not least, has anyone heard of the fuel rail between the head and inlet manifold melting slightly against the head causing it allow air in? mine has done this which in turn was flipping the gasket and allowing air in? the garage i took my car to put some sealer along the top of the fuel rail for me as a temporary measure until i can find more out about this which has stopped the air leakage for now. i rang audi today to ask if it was common but they said it WAS quite common with the 1.6 model but not the 2.0l. if it is common does anyone know of anywhere i can get a cheap one from as with crimbo round the corner im really strapped lol!
SORRY FOR THE ESSAY!
once again any help many thanks!
