Interested in seeing if you have any resolution or new info on this? I am having some of the same errors randomly coming up. Was fine a few days ago

 

Looks like the transmitter that handles the input from the wheel speed sensors might be bad or going bad? I wonder if it has internal power storage and the battery is failing? Something else to check would be the wheel signal mechanisms (rings?) and readers themselves.

 

With all the rain, snow, ice and cold mine has sat in the last few days it wouldn't surprise me if a sensor got soaked or something that simple

The bad part is my power steering pump was making some racket earlier so I need to figure that one out. The fluid for it is $26 a quart so I hate to mess with it too much. If it were cheap I'd start with flushing it with new fluid.

Weird that it was perfectly fine a week ago and the errors came up as soon as I started the car

Could very easily have air in the system. Maybe lift the front end and cycle the steering back a forth a few times with the pump cap off to see if that will bleed it? Keep an eye on the ps fluid level - It can drop quickly and starve the pump.

 

Few additional pieces of information….

1. I live in San Diego so weather is outstanding and no moisture of any type (snow or rain).

2. Also Left Speed Sensor was replaced.

3. When I tried to clear those codes with a OBD-2 Scanner, I was not able to do it, also the dealer was not able to clear them, which lead him to believe is a communication problem with “DSC” Communication Module as mention in my original tread (due to its location and the associated heat where is located. He did mention that they been replacing those on a regular basis on a 9 – 10 year car but not with only 55K miles like my car).

4. However when I got home, done some reading and played with the OBD-2 scanner to erase the codes. The way I was able to do it was by holding “DTC” button more than 10 seconds so that “DTC” will be turned off and “DSC” also gets disable. Codes were still there. However I was able to clear them with the scanner. Dealer does not know this yet.

5. Dealer sent a note to BMW NA Eng. Department to see what is the problem based on those types of combinations errors. Hope to get an answer this week and determine the next step.

Will keep you posted.
