Hello

If you have a scanner, scan for fault codes.
Do you have any warning lights on the instrument cluster (BAS / ESP / ABS) ?
Checked fuses ?

...or, did you install new, staggared tires on it recently? the sizing may not play well with the CC

CC is the first symptom of having tires with different rpm.
It usually start acting at 60- mph.

He already had a separate post for BAS ESP warnings.

ESP/BAS light and ABS light

these two lights just came on. Made sure I had plenty of brake fluid (needed topping off) Each time I restart they come on after a couple of min. At a stoplight if I restart they go off and come on after a few min

Cruise control, ESP/BAS & ABS problems - all at once?
Anyone want to give the odds on a faulty/dirty wheel speed sensor or a defective brake light switch?

Edit: Obviously best to get some codes before throwing parts at it. But whenever I buy a 'new' used w210, I routinely replace the brake light switch (and crank sensor) as cheap insurance against common failures.

They all use the same wheel sensors.
