DSC, GWS, SZL and other issues
Problems started a couple of weeks ago when all of a sudden the DSC and (!) warning lights came on. They pop up quite sporadically, but tend to have several patterns.
Pattern #1: was driving out of the basement parking lot, incline was around 30 degrees, speed under 20 kmh. Had to stop the engine and pull the key out, that solved the problem, for some time. Happened again a couple of days later under the same conditions.
Pattern #2: Moving in a straight line but catch a bump or a pothole. Normal cruising speed of around 60 kmh.
Pattern #3: Speed under 30 kmh, make turns, either direction.
Typically, I get two messages:
- 1st shows the shifter and says Start assistant inactive
- 2nd says Drive control system! Drive moderately
- some other variations of drive errors, while saying that vehicle should be driven carefully.
Indy's opinion
Scanned it, said that there were some errors with SZL, DSC and DWS, but no need to change them. He just topped the steering fluid and said that there is a leak somewhere in hydraulics system. In the end, that didn't help. just that (!) warning light now comes in orange (used to pop in red).
Official BMW dealer's opinion
- SZL and DWS errors cause the problem. Just an error, no need in immediate change, however, it is still recommended to change SZL and DWS. Preliminary cost estimate is about 2K US, but can go up if more parts are needed to be replaced.
I first decided to ignore it, since all bimmers have some electric gremlins since the day 1 they are off the assembly line. But the car started to develop yet more issues, most likely due to faulty DWS or something else.
1) Clock resets on its own
2) Put in Park and stop the engine, electrics die, can't pull the key fob out, clock and date resets. I suspect that GWS can't send a signal that it has been put in Park, hence the locked key. Eventually the system backs to normal and spits the key out. Couple of times.
3) All four windows or just driver's one roll down by 2 inches or so when u shut the door. no lock button pressed yet. Couple of occasions.
4) and when those DSC and (!) warning lights come up, audio sound keeps jumping and skipping tracks.
Has anybody experienced similar problems? Thinking of getting it to a dealer to have those
parts replaced. Looks like a big ticket... Could there be other problems beyond those two popped on the scanner?
