Well for car back tonight after garage stripped and cleaned out inlet manifold as it was full of crud. £175 quid later and the car is still the same. I'm gutted, as technician was sure that this would cure the problem. . . says it drove perfectly when they tested it afterwards. I drove less than a mile and juddering is still obvious. Question for anyone with the knowledge.... Is the car prone to have faulty throttle bodys? I assume they are electrical as I can't see a cable.No worries buddy, thanks for all your suggestions though. Car is going round to a local technician on Monday.... He seems clued up on Audi's so fingers crossed. He feels it might just be the inlet manifold needing cleaned out.
Well let you know how it gets on.
