Hello dear forum community. I’ve been having a problem since recently. My engine knocks, nails, or whatever you might call it. I’ve already handled the Sufu on extreme mishandling and partly. Problem started with unround motor running. I’ve done the following: Coils are already new, but again tested with others – no improvement idle controller cleaned – without improvement gasoline pressure regulator/limiter removed and the small gasket replaced because this was porous – while standing the car about 2 weeks. Car started and see there – runs wonderful, ABER: Now the engine knocks (video: https://www.youtube.com/watch?v=m_Ohl7LMk6Y&feature=youtu.be ) Have the screws pulled from the scrumptle to the turbo and 2, which were bolted out also lightly? The suck-up curved screws are still pulled – thanks to loose under and pressure hoses (the thin ones) were already controlled and neatly attached (something to change) – no remedy- and filter change with 5Wanks is not possible.
