What problems does the BMW N47 engine have?
Years

Answer

The BMW N47 engine (as well as the N47TU) has had major problems with the timing chain, while the N47S has fewer problems because it has oversized components. The problem is manifested as a "ticking" noise that can be heard inside the cabin, since the timing chain has been moved to the flywheel side. It is especially noticeable around 1500 rpm, and the problem is due to a faulty design of the primary gear on the crankshaft.
