Read complaints for BMW 335 (2010)
Due to premature build up of excessive soot and carbon in the egr, intake manifold, and intake valves of diesel engines, it was cause engine vibrations and check engine light to illuminate. Without costly repairs requiring egr cleaning/replacing, intake manifold cleaning/replacing, and cylinder head cleaning/ replacing, the car will not pass mandatory emissions testing. Bmw needs to extend their warranty to address this issue.
This 335d had a history of engine light-on events prior to potential catastrophic uncommented engine runaway.on jan 13, 2013 customer was driving vehicle at cruise control at speed setting 83 mph on turnpike at 11pm.suddenly engine light came on, followed by a significant reduction in engine power output.engine was unable to handle power requirement to keep cruise control speed at 83 and vehicle's speed dropped to low 70-ies mph.ecu did not disengage cruise control while engine power was reduced.suddenly vehicle accelerated uncommented back to the set cruise control speed of 83 mph.very dangerous and scary situation.vehicle was brought to bmw service on jan 16 2013 and remained there for over 2.5 months!many parts were replaced and engine light-on event was replicated several times by service mechanics.bmw center manager stated "we do not want to sell your car to any of our customer, they may have the same problems you had".ironically, vehicle was returned to customer on march 27, after 70 days of repairs and troubleshooting.customer was shown pictures by service manager of cylinder head, one of the many parts that was replaced, that was full of gunk and carbon build up.cylinder head was then apparently mailed to bmw germany for further analysis.bmw service manager stated that this vehicle was probably not the only vehicle with this problem. . . . no root cause was ever provided about vehicle's engine light, significant carbon build up in cylinder head and safety issues.
Excessive soot and carbon build up in the intake manifold and intake valves of the 335d which is a diesel car. This causes rough idling, misfires, and loss of engine power. While merging onto a highway, the engine malfunctioned due to this problem and immediately lost power almost causing a collision. The vehicle has had this problem for more than 20k miles and continuous trips to the dealer to diagnose. Finally, the dealer agreed it was carbon build up but that it is not covered. The repairs for this should be covered by bmw as it is emissions related and can cause significant engine problems. This has not been an issue on other diesel cars by other manufacturers.
Egr cooler is leaking and fumes are getting into cabin, it has disabled the abs and traction controls also cruise control! the fault came just beyond the factory warranty of 50,000 miles 4 year. I ready about your complaint service in a forum and bmw was able to complete the necessary repairs free of charge.
