What are some of the bmw f30 330d problems?

The most common problems of a BMW F30 330d seem to be EGR valves needing replacing a lot on these cars and also steering racks on the F30 cars get replaced a lot in general. Listen out for any clunks from the front on rough surfaces when test driving or from the steering wheel when turning it with the engine off. A faulty EGR valve can cause problems with the flow and operation of the EGR system leading to performance issues including a reduction in power, reduced acceleration, and decreased fuel efficiency. EGR valves can become stuck 'open' or 'closed' due to a build-up of soot particles, carbon deposits, and dirt from fuel.
