F15DOC

1999 CLK430 with 115k miles on it.
Running well, just had a right rear tire replaced yesterday.
This AM on the way to the office the brakes are "jittery"
Then lights and warnings start coming on in this order:
BAS
ESP
ABS
CEL (check engine)
When I looked I also noticed that my speedometer is on 0, I am going about 60mph on the freeway at the time.
Turned off the car and restarted and the CEL stays on.
Help, suggestions, where do I start, I am good with a wrench and the nearest MB dealer is an hour from my house.
Could really use your help.

I couldn't tell you why the brakes are jittery or the speedometer is wacko but today on my way home from work all those lights came on in my car too. ABS - ESP - BAS....I started freaking out. I did some research and apparently if you clean the brake light switch contacts or even replace the switch it should get rid of those warnings. Heres a link to that thread.

Hope this helps.

yeah...the stop lamp switch or whatever under the brake pedal could cause this. I had an ml320 and had these errors and had to replace the entire bas unit to fix it.

sometimes you can just replace the fuse, and the problem is fixed.

Listening to you guys, it seems MB throws a master switch that sets these cars off. My clk has been acting whacky too.WTF
