7 Series - E65 / E66 (2002 - 2008)
Discussion of BMW's 4th generation E65/E66 7 Series flagship. The E65 generated much controversy, due to its radical styling and iDrive user difficulties. Nonetheless, the E65 broke records to become the best-selling 7-series iteration ever, especially after its 2005 facelift.

DSC / Transmission Problem

I have had this problem for over a week now.

When I set off in the morning after 10 - 15 mins drive I get DSC fauilre and then trasmission fault coming on and turning off and then coming on again for a while.

After driving for a while the transmission comes less often. After 35 miles to work if I park the car and come back again and drive home no lights come on.

I thought maybe my battery was damaged was I have kept it on a Ctek trickle charge (via the car front terminals when not using the car for a while) so I bought a genuine AGM battery directly from BMW. I have registered it with INPA.

I had my control arms, link bars etc changed about a week ago so though it was a tracking issue. I got 4 wheel alignment which also connects to the car computer and reset the steering angle yesterday.

I got the same problem today.

I tried to diagnose with DIS and DSC not able to be checked:

Trying to force it

Looks like the scan just skipped it and on to the next module .. Once your'e in control unit functions ,, did u scroll down and high light dsc ? It should be in there ... Also you need to run a complete test plan on the Kcan line fault error . That is where the problem is ..
