Disadvantages of the Mini B37C15A engine
- The main problems for the owner are the EGR valve, which is called AGR here;
- It is to blame for sudden traction dips, loss of power and twitches;
- Compared to the N47 diesel engine, the timing chains have become a little more reliable and run up to 200,000 km;
- However, the intake swirl flaps here also quickly overgrow with soot and jam;
- A lot of trouble, as usual, is associated with the whims of piezo injectors and a particulate filter.
