So, hello. I've bought my first car about 2 month ago, after 1 month of using it (about 600 miles) I was driving on the road and stopped on red signal after I tried to move off my car started shaking and hardly move with heavy white smoke . Somehow I drew it home and left for a few days. Some guy told me it should be ignition pencils , so I changed them also spark plugs in the same time. The car stopped shaking so much , but it was hard to start it up and still heavy smoke. After that I went to the garage where they suspected misfire of cylinder 1 and 2 and timing chain. I have texted the guy who changed CDN ignition pencils and he said it is easier to swap the engine because the problem is piston rings that have to be replaced , but he said without checking it properly. I've also had stage 1 about 2 weeks it broke down . The car is Audi A5 B8 211hp 2009/2010 coupe. 93500 miles. I'd be really happy if someone has had similar issue or knows how it might be fixed.
