E60 N53 burning oil in cabin
I have a E60 523i with N53 engine which when I bring the vehicle to a stop, the inside of the car fills with a plume of burnt oil.
We have had many issues with the vehicles performance and often producing a white cloud of smoke at rear, which BMW says is water build up.
So far we have had:
All injectors replaced
Radiator change due to leak
Rocker cover gasket and all bolts
The vehicle is consuming rather allot of oil and economy is not great.
Can anyone advise where next to look as I am stumped.
Thankfully it is still under full comprehensive warranty but so far two BMW master technicians have not been able to locate the fault.
