Well, Folks, I figured out focusing on the ABS sensors in terms of
1. cleanliness and tighthness in the hub
2. fine electrical connection in the plugs

Symptoms:
1. Illuminating DSTC light and error message (DSTC WART. ERFODERL.) going over a bump or at sharp cornering
2. Restarting the car: no ...

Pops up, after restart: disappears.
Any idea, please?

Don't worry, but unplug the battery before you remove the phone unit.
Cheers!

Removed that old fashioned cigarette lighter and retrofitted by some useful tools.

The socket came out very well, but its size was smaller for this USB connector: a hole polisher in the drill did the job.

Advantage: there is a dust cover reduces the light of the blue numbers at night.

Good DIY ...
