BMW Turbo Problems
Discussion
BMW X3, X5, 320, 520, 330, and even the mighty 730d, they all seem to suffer
from turbo problems. The main reason any turbo will fail is poor condition of engine oil, the oil is left in the engine for to long and loses its lubricating qualities, once this happens then the bearings in the turbo fail and of course the rest of the moving parts in the turbo such as the
turbine and compressor wheel will be destroyed. After you get your turbo rebuilt or replaced then I recommend the following, replace the oil feed pipe
and engine breather located on top of the rocker cover, drain out any oil
in the engine and fill with a cheap oil for now. start engine and run for 10 minutes then switch it of and add an engine flush. Run the engine for about 40 minutes then switch it of, remove the oil filter and let any oil in the filter housing drain down into the sump, remove the drain plug then let the car down until its level to ensure every last drop of oil gets out. Fit your new oil filter and the drain plug then fill the engine with recommended oil. Long life oil dose not work so change the oil every 6000 miles and you will never have BMW turbo problems again.

I'd suggest that it's not the oil that is greatest concern but the oil breather and the fact that it isn't a service item. The oil gets changed, filters get changed (whether DIY or by a dealer) but the oil breather doesn't.
That's what breaks turbo's over time not the oil in my opinion.
My advice on buying these cars/engines is to disconnect the EGR (if appropriate), change the oil breather to the new vortex type (£50) and give it a good service.

My breather/ crank case breather/ oil seperator was recently serviced on my old 120d- mind you it was on the 6th service (circa 75k miles)That's what breaks turbo's over time not the oil in my opinion.

It mainly seems to be a problem in colder climates (Canada,Scandi etc) when cars are driven short distances.
