Hello! I have a A4 1.8t which developed a starting problem and an engine management fault (camshaft position sensor), took it to my local VW/Audi specialist who after a week failed to find the cause. My next step was to take the car to a tuning specialist, they also struggled to find the cause of the problem and after two weeks advised me to have the cars chip replaced. On completion of this I was told the starting issue had been fixed, this was true as it started first time! unfortunately this is not the end of my headache as the engine management light is still on (same fault) and worst of all the cars rpm's are all over the place when ticking over. Any help would be greatly appreciated!
