I own 2 bmw 335d's, one a 2010 and the other a 2011. i cannot keep these cars on the road. i have had "service engine soon" lights constantly. every code leads back to the emmissions system on these diesels. the latest is an scr code that is thousands of dollars to repair. bmw came out with a 10 year 120k mile extended warranty on the problem. they should have come out with a recall! i have had so many service engine lights i cannot afford to keep these cars on the road. these cars are worse than the vw diesels. the cars runs great, yet because of the service lights the rpairs are more costly than the cars are worth. i asked the murrieta bmw to ask bmwna to see if they would repair the scr active tank and was declined. i run the 2010 bmw many miles on the freeways so the scr active tank problem didn't show up until 186k miles. my 2011 bmw which isn't driven on freeways is much had to have that tank replaced at 117k miles. when talking with the murrieta bmw service manager, he agreed when i told him these cars are crap. when the service manager had nothing good to say about the cars that speaks volumes. the blogs on the computer are loaded with complaints about the emission and def systems on these diesels. help, i truely have two cars right now that are worthless! the service managers advice was to turn them in to a dealership and get new(er) cars... really, pass the problem onto some other unsuspecting person when bmw knows these cars are more than a problem - unbelievable!
