Summary of diesel turbo failures from there (1) 車主 A , 530d After 72k miles the turbo went yesterday. Good thing is that it happened 3 months before the warranty runs out. The summary of faults from the BMW system is now 19(!) pages long.
(2) 車主 B , 530d 3 weeks ago I was in the same situation. My car, 530d, almost had 155.000 km when I blew the turbo. Since we only have 2 years of warranty here in Belgium and my car was almost 3 years old, I was afraid to pay the full monty! But, since BMW has the policy to pay some of the costs for every car less than 3 years old, I only had to pay 30% for the turbo
(3) 車主 C , 530d My turbo went away at around 65K km. I was in Germany on a business trip and decided to go into a shop for a checkup. They diagnosed my turbo as "will die soon" and then changed it. The car was just one month out of warranty at that time. Thankfully BMW covered this as post-warranty and I only paid the labor. Then a week ago, at 112K kms, the turbo died again. This time I believe it is because of a pressure sensor that was defect since one week before the turbo was changed. In that week I put another 1.2K kms on the car (my SA said that I can drive it but will have some missing HPs). Now I believe I will drive it more carefully than it was a shopping cart full of eggs. Oh well, and in my case too the car was driven hard sometimes but only after proper warm-up and after longer trips the turbo was left to actively cool off. My car is an 530d.
(4) 車主 D, 530d i have a 06 530d and just found out today got blown turbo. haven even had it dms yet. car done less them 10k miles
(5) 車主 E, 530d 91K and the turbo blew last night, well I think so....loss of power and white smoke??
6 車主 F, 530d I had an E60 530dA with 100k km and the turbo was probable going to dead not in far future (a lot of oil leaks in pipes = bearings wearing out).
Conclusion The E60 diesel turbos has about a 150k km or some 100 k miles change interval. All facts came out of the single turbo 530d.
I'm wondering if a twin turbo 535d could live longer
