I have this car since 2014 it is very good on diesel 5L./100 km. It has been very well maintained during the time since I am the owner of the car. It has been serviced recently. And is in very good shape. The engine is strong pulling like a train. Tyres in very good condition ready to go. It Is not ulez. It is good to be used for not ulez zone areas. Since I got the car it has been only with Castrol Edge 5W30M oil long live change on really short intervals 5000 milles. BMW recommend Castrol for their engines. I have a full service history of the car. The DPF filter was cleaned around 2 years ago and is really in very good shape. Very good reliable car. Also it is fast for thise engine.
