Hey guys i have a 2008 128i and have had some concerns. Ive read a ton of information on the web about the infamous valve tap. Ijust bought my 128 a month ago from an euthisiast who babied the car. I have noticed recently that the car can have valve tap, but it is completely random. Sometimes it happens, sometimes it doesnt. Weather doesnt affect it at all, or whether the engine is warm or cold.
I have attatched a youtube video of my car for you guys to listen to.
I need some opinions/thoughts on what i should do. What is bmws valve train warranty? Any help is appreciated. thank you!
