CLK 320 ABS, BAS, ESP problem
Hey!
I'm having a very strange problem on my CLK.
The ABS, BAS and the ESP lights up on the dash when I've been driving it for 2-3 minutes (nothing lights up on start up)
I've cleaned both of the reluctors in the back and cleaned all the ABS sensors as well.
I bought four new ABS sensors and installed them but the problem wasn't solved so I brought them back to the shop and installed my old ones again.
What happens when the lights appear is that the car goes into limp-mode (locking itself into the gear it's in) if I shut the engine off and start it again the lights goes away but comes back when I'm driving again.
If I take off the two fuses under the hood (5 and 40 amp) the ABS, BAS and ESP lights light up when starting the car but it drives good like it should and I've also changed my brake pads and discs so when removing the fuse the brake pedal takes very good (almost on top like it should be) but if I put the fuses back in the brake pedal vibrates like the ABS is in and it goes down to the mid and there the lights come up, has anyone ever had this problem?

CLK 320
This is what I got from the diagnostics:
C1200 - brake light switch (I've replaced it twice just to be sure)
C1500 - rpm sensor, plausibility incorr. teeth no.
C1504 - system switched off, steering angle sensor not initialised
No steering angle initialising
what do you mean with module? The ABS pump under the hood?
This happened when I changed my tires in the back from 285/25-20 to 275/30-20

An important issue in the selection of your tires, is to make sure that the rolling circumference of the new set up is not more than a percent or so, different than the OE factory wheel and tire size set up, on both axles.
Reason being, the various sensors provide important inputs to numerous vehicle computers (e.g. transmission, braking, cruise control, electronic stability / traction control programing, not to mention your speed sensitive power steering, radio volume, speedometer/mileage etc.).
Tire size Sidewall Radius Diameter Circumference Revs/Mile Difference
285/25-20 2.8in 12.8in 25.6in 80.5in 788 0.0%
275/30-20 3.2in 13.2in 26.5in 83.2in 761 3.5%
PS: Also, whenever your vehicle battery is disconnected, you have to initialize the steering angle sensor, as described in your owner's manual.

Secondly, I would still think its the brake switch as they are delicate and you must by original Mercedes, OEM will fail from experience.

The factory setup on your CLK320 is 205/15-16.
Your rolling circumference with the 285/25-20 tires was only 2.9% more, while the rolling circumference with the 275/30-20 tires is 6.5% more.
