The "NO DS" things can be triggered by a number of things, being the most "famous" (or infamous I should say):
- A faulty PRNDL board
- A broken wire on that same board (blue harness)
- A broken wire from the loom right below the shifter plate (most likely a blue wire)
- Someone once mentioned a "solenoid valve" on the gearshift assembly.
The most successful fix is:
- Getting a new gearshift assembly: $450 + Labor (around $900)
- Finding the broken wire and either soldering it or splicing it. (free)
- Replacing the PRNDL board (around $35-$50 on ebay).
In my case, I have tried everything but replacing the complete gearshift assy. for obvious reasons.
Interesting find: While playing with the gearshift and shifting it from D to the DS mode I hear a click and found it comes from a contact sensor...could that be culprit? maybe but I have no way to access it or replace it as I doubt I can find that off the shelf or have bmw sell it to me.
Anyways, try what I outlined above and search for one of my posts where I posted pictures and a link to a DIY for this matter. Good luck!
I really appreciate it. I plan on taking the center console apart this weekend and I pray that it is simple as a wire that needs to be soldered, but your list will be a great help if it isn't that simple.
