Disadvantages of the Mini N47C20A engine
- The timing chain is a modest resource here, sometimes it stretches to 100,000 km;
- At about the same mileage, the crankshaft damper pulley usually needs to be replaced;
- Often there are antifreeze leaks through cracked seals in the cooling system;
- The swirl flaps of the intake manifold coke very quickly and wedge;
- As always, a lot of problems are caused by contamination of the particulate filter and the EGR valve.
