Hi. Friend just bought this and all was fine until half hour later and half way home. Seems to lose power at 1-2k revs when trying to accelerate away especially in 2nd and 3rd. Also it wasn't happy (juddery) on the motorway in 6th at 50 cruising. Intermittent but hardly ever under heavy load like up hills. More noticeable at lower revs and more when hitting the gas coming down a hill after going up it. When we got home on idle with a warm engine the engine judders like a soft misfire which is very prominent at the exhaust end. No dash warnings and no faults codes from my (basic) ecu reader.. Ive read egr pipe feed cracked. Knackered coils or plugs. Bad coil earth. But unsure where to start. I'm tempted to wait for a fault code to show up... Any ideas? Cheers chaps

Right okay. He took it garage and they cleaned out throttle body, did the terra clean treatment, changed plugs and filters and it was fine for a week. Then it came back but much less than before. He took it to local vw specialist and they managed to get some codes off it. And has been referred to a fuel pressure specialist which he is seeing in a week or so. What do you guys think this could be or if you've had similar what was the actual cause? Trying to figure what the cost might be.
