Fuel economy data from fueleconomy.gov (EPA / U.S. Dept. of Energy). Annual cost based on 15,000 mi/yr at 55% city driving and current fuel prices. MPG is U.S. gallons; L/100km converted.
The 2010 BMW 335D draws the bulk of its complaints around the engine and emissions system. Owners frequently report recurring fault codes tied to diesel emissions components, NOx sensors, the selective catalytic reduction system, and catalytic converters are all mentioned as failing, sometimes repeatedly on the same vehicle. Repair costs in this area run into the thousands of dollars. The electrical system and steering each account for a pair of complaints, including one owner who describes an ABS sensor failing multiple times and another whose vehicle stalled and shuddered before the ABS warning light came on. One isolated report describes a vehicle catching fire shortly after parking, though that stands alone in the complaint set. The emissions-related engine faults are the clearest recurring pattern owners describe for this model year.

By System
The 2010 BMW 335D has 5 recalls, the most serious being a driver's airbag inflator that can explode during deployment, sending sharp metal fragments into the cabin and potentially causing serious injury or death.
The airbag concern stems from a steering wheel swap: if the original steering wheel was replaced with a sport or M-sport unit carrying an incompatible inflator, that inflator can rupture violently rather than deploy cleanly. On the electrical side, there are two related concerns about the positive battery cable connection at the fuse box. That connection can degrade over time, causing intermittent loss of power that may stall the engine without warning while driving. Prior repair attempts did not fully resolve the issue, which is why two separate recall campaigns address the same underlying problem. There is also a wiring concern tied to the heating and air conditioning system, where the wiring and electrical connectors controlling airflow can overheat, melt the connectors, and start a fire even while the vehicle is parked and unattended.
