Hello,
Newbie to the C63 world.
I've serches thru the manual. I've searched online but only see posts on 'Inoperative' and not 'Disabled'. 2014 123K miles, when i start off in the morning distronic cruise control works, but after a few minutes it shuts off. When I try to select it I get a yellow message 'Distronic disabled'. Everything else works perfect, lane change assist, Nav...etc. I do not get a message 'Aux Battery'. Is it the Aux battery or the actual sensor? Any ideas what to check, measure before replacing parts? Any help appreciated, BL

Now the message is, 'Distronic Inoperative'.
Anyone done any diagnostics on this issue?

what's the code? otherwise this is like guessing what the check engine light is on for.

Yup, I get it. I have a simple scan tool that I diagnose trim levels. 02 sensors ..etc, on my truck, i haven't tried it yet but I'm guessing I need a unique scan/code reader to diagnose this issue? If that's the case, which one are you guys using? Thx for response.

I use a Xentry , but Chris Sullivan (youtube channel) uses these with success

Foxwell Scanner (small one): https://amzn.to/48uMwCA

C2215
C3438
Are the ESP codes I'm getting. my scanner won't read steering angle values.

also SGR - radar Sensors Control Unit
5304 - radar sensor 3 is distrupted by interference from an external source
5204 - sensor 2 as above
727C00 CAN Bus: one or more signals sent from control unit N30/4 (electornic stability program control unit) via the CAN Bus is implausible
C343800 - the power suppy is outside the valid range

I've purchased this I'm hoping I can dig into these codes more but shout out if anyone has any advice.
