haha, I feel your pain. My diesel spent more time in the shop than out of the shop. My family was always interested in what loaner I would have next. I used to joke the SES light was the car indicator that I've driven too far from the BMW service bay.

Seriously though in the 1st year of ownership (I bought it used and under warranty), I only had it out of the shop for maybe 12 weeks. I want through CBU, multiple EGR (5x) valves, (4x) EGR coolers, 2x diff pressure sensors, 4x nox sensors, 5x exhaust pressure sensors, vacuum hoses, 5x MAF sensors, SCR catlyst, DEF tank, DPF, haha, in less than 45K miles. Now it needs a vibration damper, just replaced the battery, diff whine.

But it is my unicorn (e90 diesel) and in spite of its total lack of emissions reliability I still like it. But that is why I went GAS for my next vehicles. Now I've spent several thousand tuning and removing the emissions equipment. P.S. most of these reliability issues were never solved by the factor other than extreme CBU. DEF tanks are a 50K service item typically. That is why I say you wont save money on a diesel compared to the 35.i
