Disadvantages of the Mini B37C15A engine
The EGR valve, also known as the AGR here, is the primary cause of the owner’s issues; it is responsible for abrupt traction dips, power loss, and twitches.
The timing chains are now slightly more dependable and can travel up to 200,000 kilometers when compared to the N47 diesel engine;
However, soot and jam also quickly overgrow the intake swirl flaps here; as usual, a particulate filter and piezo injectors cause a lot of problems.
