oh the problems i've seen

2010 BMW 5 Series 535i xDrive 4dr Sedan AWD (3.0L 6cyl Turbo 6M)


The direct fuel injectors have introduced a new and not insignificant problem to the engine. Coke formation is extensive. Those engine lights that start to light up anytime after say 50K miles are likely due to carbon buildup in the cylinders with the sensors going crazy as a result. Big engine lights , little engine lights, single and multiple cylinders dropping out at highway speeds, LTFT abnormalities, O2 sensor malfunction codes, cylinder misfiring codes, and on, and on.
You can spend many an hour chatting with your local mechanic getting to know all about his kids and their little league activities before you get to the necessary therapy: walnut shell cylinder coke blasting! ($800!)

Best Features

What a beast when functional. But I don't need it to sit in the drive way for me to listen to music and go "zoom...zoom " as a 5 year old in the driver's seat of mommy's car. I need it to transport me as well.....reliably...without fear of failure.....after replacing fuel pump x 1, tail light assembly x 2, O2 sensor x 1, manifold intake sensor x1, fuel injector x 3, coil pack x 1, plugs x 6, carbon blasting x 1; all between 60 and 95k miles. Do yourself a favor. When the lights start to go on, do the carbon blasting first. Then start to replace the parts!

Worst Features

Serious re-engineering for the direct fuel injection system needs to occur &/or BMW needs to include a free carbon blasting every 50k miles for the duration of the automobile's existence.
