Unfortunately these continue to come on about once a day. I thought the issue of the different tire pressures had solved the problem but they are all spot on at 28 psi and it continues. It has all new brakes including discs, pads, wear sensors and new calipers and hoses in the rear (they were both sticking).

The brake pedal feels normal when I'm driving the car, but when parked it seems soft and when I push it all the way down I here what sounds like something is "ratcheting." When I do that then turn the car off the lights will either be off when I start it again or will go off shortly after I start driving.

I did replace the brake light switch with an OEM MB part.

They seem to come on at random. I'll be driving along and suddenly they just pop on. My mechanic had scanned the car and while he got several pending codes for other things, there were none for the ABS or ESP.

Any ideas what to look at next, or revisit, thanks.
