B200 Pre Safe Functions Limited?

[B200Sport]

Hi new to the forum,

I've recently been having an issue with my B200 13 reg.

The below has happened twice now on the drive to work.

• Sudden appearance of Pre Safe Functions Limited warning on display.
• Parking brake amber warning symbol.
• ABS amber warning symbol.
• Run flat indicator inoperative warning.
• No power steering, cruise control, limiter.

It usually disappears after a restart or during a drive home.

I've taken into a garage once, they were unsure but suggested it could be a sensor issue so might be a good place to start.

It seems like the problem below:

Is it possible to diagnose myself? How would I go about checking the wiring loom?

Hi and welcome
Could be a speed sensor or ABS sensor but these cars thrive on proper diagnostics - I'd suggest a visit to a good Mercedes Independent garage for same, using Star. Where are you based?
