I have 2009 A4 2.0L Turbo Quatro, the engine starting to shake at idle or when I stop at a light, when its on normal moving speed it does fine but it idles rough, what could be the issue?
2009.. turbo.. I would say the turbo might be failing... either that or you need new plugs. Audi's have a tendancy to clog the engine with carbon if your rough with your gas peddle so this could also be the issue.
