Braking Issues
Took my E90 335 in to check the brakes out. I have steptronic and about 15-20% of the time when I release the brakes, the car would lunge forward. There is some kind of delay when I release the brakes. Usually when you slowly release the brakes, the car moves gradually forward but mine hesitates, then jerks forward.
Anyways, I explained it pretty clearly to the SA and the punk says it's normal and part of the hill decent feature where the car brakes for you so you don't roll back. But my issue is on normal flat roads. If you can imagine, parking in my garage or in front of a wall is kind of scary because I might hit the wall. I'm used to it but any other driver will have a problem. I also complained of some hard jerky shifting from 1st to 2nd gear on cold starts but the SA keeps insisting it's normal. The car is normal once it warms up so it's not as big a deal as the brakes. I'm kind of frustrated at the SA and how he kept saying that it's normal for the E90's brakes to behave this way. I've never heard of anyone else having this issue on this forum. Anyone else experience this??? |

He's right. It's awful, but mine does the same thing in the garage on a level surface. You can't slowly move the car forward. The brakes grab really badly.
And, it's not just he 3 series. My nephew has a new 550 and his car does exactly the same thing. It would be nice if you could switch off the hill holder feature, because this braking thing makes you crazy, besides almost hitting the wall each time. Sorry, but that's how these cars work. Doesn't make it right, however. Larry in Los Angeles |

I have a manual and the symptoms are a little different but there is no gradual on the brakes - they are on or off. Makes for very jerky driving when going slow or even upon first application of the brakes.
Even though they aren't brake by wire there is some computer intervention here will allows for the hill holding and other "advantages". I'm hoping a software fix will come along. Service people at stealers aren't interested in any non-normal problems.

That sucks. It could seriously be a safety issue and should be recalled. If you let someone borrow your car and they're at a stoplight and pedistrians are crossing, they can potentially lunge forward 4-6 inches and hit someone when they intentionally only wanted to creep forward an inch.

My 330 does the same thing.

Search for "bedding in brakes". I had the same issue and bedded my brakes and it's all but gone. Chances are, your pads and rotors have glazed. You can also try brake cleaner, but bedding them in is more fun!
