Hello, I'm new here but have found a ton of helpful tips. Currently my cars BAS ABS and break lite are on. The car will not shift when the break lite is on. I read its a break lite switch. Is this simple to do you yourself? No one wants to look at my car because they don't know how to and the cars shifts perfect when lite is off.

 

Hi!

Welcome to MBWorld and thank you for checking in!

Moving to the W210 forum, good luck!

20 to 30-minute job to replace the brake light switch. It's more difficult to remove the panel under the dash than it is to replace the switch. 1/4 turn clockwise, pull switch out, unplug from harness, ensure central plunger is pulled all the way out on the new switch (not collapsed to minimum position), connect to harness, insert in mount and rotate 1/4 turn counter-clockwise, reinstall panel.

Panel has screws and clips; you'll need to remove the screw for the hood release latch. IIRC, the OBD2 connector is released by pulling a plastic collar to one side. Some photos here to give you an idea prior to going in: https://www.benzworld.org/threads/ch...panel.3035719/

Internet search on W210 brake light switch replacement.

 

Get the OE MB or Mopar (Crossfire) brake light switch ONLY - the cheap China replacements sold generic at autopart stores are at best 50/50 - do NOT use Uro as shown in this video
