Mercedes CLK 200K ABS, BAS, ESP lights came on.
is there any degridation in performance? sounds to me like it's in 'test mode' when the key is first put in, to make sure they all work...stuck in this mode. perhaps the milage has made toast of your ignition switch-
when i put the key in and switch the ignition on, all these lights come up.
Could it be a 200K service reminder? Maybe all those systems are bad. Get the codes read.
I had a similar problem with my 97 E420. In my situation, it turned out to be the K40 relay module.
If those reminders stay on after starting, it might be possible that the ABS Front Wheel Speed Sensor are defective
