My vehicle has the same incident about a dozen of times in the last 4-5 years. The vehicle suddenly had check engine light, ABS light, traction control light, and brake light on, engineer started to knocking, speed forced down to less than 30 MPH within in seconds. It was quite scaring when the vehicle was on the highway with speed at ~50-70 mpg. My dealer has made several repairs, changing everything in this speed controlling system multiple times according to the book, including throttle body twice, electric harness three times, and control computer unit once, but the problem recurs. Occasionally, resetting the system and/or restarting the car, and sometimes reconnecting every parts of the system can avoid the problem for a while (from a days to 1-2 years). Although it is unpredictable in when, it would come back. The problem seems to come more often when the weather become more wet. This mimics the behavior of the poor electric connections controlling the tails and turning lights of the same model, which was recalled by bmw a couple of years ago. It seems that the same electric connectors are used in this speed controlling system. Obviously, this problem is more dangerous than the signaling light issue since it is more likely to lead to severe accidents/crashes in the highway; I might be dead or severely injured if I did not responded quickly enough when was in I-95 for example.

Went to go into reverse after coming home from a shopping spree and the car simply would not reverse. After a few days it finally went into reverse. Engine light stays on and there are transmission codes on the indicator from this. Can't afford to fix this problem but there are several reports on the 325 I bmw.

Car ran perfectly, then I turned off, then I restarted 5 seconds later to reposition in garage. Engine then revving from 800 to 1200 RPM rhythmically, approx once per second, eml light on, brake light on, service engine light on, very hard to stop car, had anyone been close I would have hit them. Engine revving continued for 2 days, then went away on own. I then took off airbox to inspect maf, filter. Codes on 3rd day: p1632 throttle, pending: p0102, iats. There have been other incidents over the years of restarting engine to have extremely rough idle, also cleared on its own, but never surging like this.

I went to start my vehicle in the morning and it started and then turned back off on its own. This happened about 3 times,before it stayed on. I then drove the vehicle about 40 miles and the transmissions started to thump. The vehicle only has 100k miles. I kept up on all its maintenance. I took the vehicle to the dealership and the transmission light and check engine light both came on. I was informed it would cost 6,500 to repair my transmission.
