No. My issue is the lifespan and frequent failure of emissions components on BMW's common rail diesels. Which also deserves credit as they were the only manufacturer that I can think of (and I had about a year and a half during Dieselgate to read all about it) that hasn't been found to cheat on modern diesel emissions tests.
For example, o2 sensors, catalytic converters on gassers are rarely talked about failing and especially not during new car warranty period. They aren't maintenance items.
None of the emissions components (NOX sensors, urea tanks, DPF, SCR catalyst, etc) are supposed to be a regular interval maintenance item, they are supposed to be "lifetime emissions components" - but the way they fail often and multiple times as evidenced by many owners shows the opposite.
This is what led Volkswagen to cheat emissions on their CR diesels, because if they ran the software at full emissions all the time it would lead to early component failure, so obviously we are seeing that BMW did not cheat like VW did -
There are reports of some DPF failures on the Volkswagen boards early but for the most part the owners were told that the Gen 1 TDI's (the ones without urea) once fixed to EPA standards would carry certification for 10y/120k miles on the emissions warranty, and for the Gen 2 and Gen 3 cars that also had urea injection, it would be 12y / 150k miles -
I am getting into too much Dieselgate info here but our foray into the 35D here is a direct foray into it. All I will say is that bought back by VW at 35k miles literally all I did to the car was change the oil and put diesel in it and have the fuel filter service done once.
Yes VW cheated but its something to consider.
Vast differences with the emissions components when contrasted to our 35D's (and as Thecastle will report, on his 335D)
