Came across this x35d with 224,000 miles on Autotrader

I dunno, I've had tons of trouble with my BMW diesel. I would not say diesels are more reliable than gasoline cars. I would say with modern emissions they are less. But some folks have great luck.

I've had Lots of emissions failures, lots of mechanical failures on my 2011 335d. They aren't reliable but they are fun, mine is now JR tuning stage 2 now that the warranty is out. Under warranty my 2011 335D was in the shop constantly, so much so my family was always curious as to which loaner I would have next, and I wouldn't see the car for months at a time while BMW scratched its head about what was wrong. In fact I found buying a used D the cheapest way to lease a new BMW ;-)

I didn't buy a 2nd diesel when I purchased my X5 becasue of the nightmare of problems my 335d has. But then again I'm an owner of an N62 so I guess I'm a glutten for BMW's lack of durability. I havent gotten rid of the 335D mainly becasue I enjoy it and its deperciated so fast I'm still upside down 2 years latter with a 20% downpayment and extra payments...

The diesels have the following trouble spots
ABC's (EGR, DPF, SCR)
Carbon build up x1000
Vibration damper failures
vacuum hose failures
eat engine mounts
Boost hose failures
EGR cooler failures
injector failures...

I'm hardly unique... I've replaced my EGR valve 3x, EGR cooler 4x, MAF 4x, Differential Pressure Sensor 4x, DPF, SCR, SCR tank, Boost Hoses and I have less than 55K miles.. I also just replaced the battery and I'm about to do the vacuum hoses and vibration damper.
