W210 E55 warning lights query

[W210 E55]

Yesterday whilst parking I turned the steering full lock right and immediately I had multiple warnings pop up, esp, abs, bas, also no cruise control. Is likely to be the usual brake switch or something more serious?

Could be the brake switch or anything else in the Brake system.

As it occured when turning the steering wheel it could be wiring in the column? Needs a Star check to be sure.

Is the car in limp home mode...if yes, then its a rear reluctor ring...if not could be a brake switch.

It's not limping and drives fine, I'll pull the switch out and have a nosey inside

Obviously we're all guessing here, but being that you were turning on full lock, it could be worth checking the steering angle sensor?

I think if the battery is disconnected for a certain period of time then you usually need to reset the ESP etc by turning full lock left-right a few times.

Easiest way would be to get it hooked up to STAR though

Took the switch out and opened it up. There are four wires to the switch, brake light power in and switched out, and two others whilst unsure of the source and output they make contact when the brake is not being pressed. Inside the switch is a small metal contact which makes the connection, it is this that had snapped. It's very thin and can only have a limited life. Not possible to repair so put it back together leaving the two non brake light wires off and temporarily shorted to prevent the warnings, although this will probably mean cruise won't turn off with brake press. Will get a new one ordered tomorrow.
