Hello, new here,

I have a 2002 CL55, and recently out here in California been getting colder weather in the 40's, and in the morning during cold start I get BAS, ABS, Speedtronic messages on my dash, also during this time the steering wheel moves up and down, climate control display goes in and out and if I turn on the seat heaters on the red light goes off, I cants seem to find any info online of anyone else having similar issues, my battery just got changed, AGM battery. I do have a scanner and can see my battery voltage, before I start my car the battery voltage is at 12.2 and drops to 10 volts when starting then goes up to 14.3 volts once car is started, after car runs for a few mins the steering wheel and climate control stop doing there thing but the error messages are still displayed, turn car off and restart and all back to normal. Any input would be helpful, it's bugging the heck out of me and want to try and figure out what's going on,

thank you


This only happens in the morning on cold start, if car sits at work all day and is cold again when I restart all normal

Stick with me on this one.

Ground points are getting worse over time and these cars have a lot of shared ground points.
It might be that because it's cold and there is more water in the air than when it's hot, that the already bad, but still kind of working ground point gets to the point that it's completely bad.



How are your water drains in the engine compartment? Is there any dirt inside of those?
