ABS warning light, ESP and Brake assist, cruise control, inoperative.

Hi, I am getting these warnings intermittently on my 08 WDB211 E220. They go off when I stop and restart, then it happens again. Should I be worried? How do I trace the root cause and fix please? Many thanks, Chappers

read the codes (SDS preferred), check your main battery is at full charge/health

Possible brake pedal switch failure , search you tube ...

or maybe a ABS wheel speed sensor

Or a reluctor ring on the back. See how important a code read can be?

moral of the above posts is get the codes read.

Indeed , speaking from experience and even then it was a loose earth cable. Which star didn't point out.

Thanks to all...

I would like to know how the problem was cured, please.

There is not a one shoe fits all repair for the above. You need the codes read by a competent indy with a adequate reader.

It has suddenly settled down. I am waiting for the fault to reappear then take it in to get the codes read. Will post when facts become apparent. Thanks for all interest.

Thanks for that.
It seems to point to a low charge in the battery.

That is interesting Matt. I will put it on charge to give it a good boost.
