Hello everyone, after many advice here on the forum i changed my camshaft with all the necesery components, (cam follower, chain, chain tensioner, O ring, head cover seal gasket, chain cover seal gasket etc...) first 3 or 4 days i dont have a sound, engine was very quiet at idle or when i drive. Then a tapping ticking noise begin, and comes with error code P0328 KNOCK SENSOR 1 (G61) signal too high and P2261 Boost pressure control valve mechanical malfunction. Sound comes from the top of the head. And when i drive it doesnt matter which gear km/h or rpm, its like a took off my foot of gas and i press, its like a little bit shaking or some kind of this i cant explain that exactly. Before i change everything i dont have this taping sound, just engine was a little bit more noisiest. I make a video i hope you understand it because at the video noise is a litle bit quiet then it sound at real. Thanks guys.
