Hello,

Did you have a battery replacement or so ?

Try this first :

Turn the stearing Wheel full to the left, then to the right and get it Back to center, it will reset the ADS calculator.

Regards,
Frenchy.

A couple years ago, my ADS light was quite intermittent. Took a while to track it down but it turned out to be one of the accelerometers in the engine compartment. Extreme temps (hot or cold) would affect the darned thing.
Cheers,
Jeff

Does your vehicle have the hydraulic fluid suspension system? In the engine compartment near the wind screen washer fluid is a hydraulic fluid container that will trigger a dash warning light in my 600. I check the fluid first. If in LHM, the problem will need a code reader and a mechanic.
To reset many codes ( as a DIY ) the negative pole on the battery can be disconnected, and give yourself hours before you reconnect. After starting the car, turn the steering wheel full right-left cycle to get the warning light off and reset radio codes. I test drive to see if any warning lights come back on. The most common CEL for me is dust in the air intake!
The wheel sensors have been an age or damage problem only for me, but when renewed they have been flawless!
