Hi magnet I had it serviced recently, so from full I got approximately 400ks before the light came on. Again Ive replaced the plugs across each cylinder once in that time. I removed the pcv pipe feeding the inlet manifold and closed it off (on the manifold side) which did help, but again there’s oil residue getting in somewhere. I removed the intercooling pipe just below the throttle body and noticed some oil coating. But before stripping down and checking the oil level at the intercooler is it worth my time and money. I’m starting to lean towards a leak down test also. I haven’t ruled out valve stem seals but there’s no sign of smoking on starting. Now and again there is signs of moisture from the exhaust black in texture however not oil based. Proving hard to diagnose with the issues provided. Have you any advice on this? Cheers Chris

Hi guys I have an A3 2011 1.8tfsi s line edition. Reading the thread I have similar problems burning oil however I noticed no one has mentioned a misfire issue. Has anyone had a misfire? Carried out a compression test which was good and had the walnut cleaning around the valves to remove carbon. The car ran well for about 200k. Then back to the same problem. I replaced the pcv valve but still facing the same issue. The misfire moves from cyclinder to cylinder with carbon build on the plug and eventually wet with oil that it won’t fire. Anyone had similar issues and managed to get to the bottom of it would be much appreciated to hear from you. Thanks Chris
