I have an 06 330 MT. When I start my car, the following lights and messages are displayed below.



The car appears to brake just fine. After perusing various threads, it was advised to inspect components such as fuses, relays, the DSC module, and cruise control. While I've confirmed that all the fuses behind the glove box are intact, I'm uncertain about which relays to inspect. My car has operational adaptive headlights. However, the cruise control is non-functional, and its warning light illuminates upon attempting activation. Codes S 0085 and S 0158 can be cleared. It appears that I can drive in the forward and reverse direction. However, the moment I drive normally, normally in terms of moving the steering wheel to the left or right, the lights reappear and so do the codes.
Any guidance on an effective diagnostic approach would be greatly appreciated valuable.

Here are the diagnostic codes sourced from ISTA:

S 0085: No communication possible with Dynamic Stability Control (248028 yes)
00D904: CAS: K-CAN line fault (247976 yes)
S 0158: No communication possible with Park Distance Control (248028 yes)
00E2C4: CON: K-CAN line fault (247976 yes)
00E444: SMFA: K-CAN line fault (247976 yes)
00E5C4: CID: K-CAN line fault (248024 yes)

May I please have help with this? I've been looking all over for a solution to this but I'm not finding anything solid.

It’s good you have access to ISTA!
What does the test plan state?

Cruise control and DSC are linked.
