- Mercedes-Benz E-Class: How to Replace Brake Line
Step by step instructions for do-it-yourself repairs
"Brake - Visit Workshop" message = stop light switch = $10 part / 10 minute Easy DIY




dollars. It located right under the driver side dashboard on the firewall. Very easy job to do, get the part from th dealer
Changing the brake fluid typically requires the use of MB's Star Diagnostic System, which in turn would also be able to reset the computer message. If your mechanic does not have one or know when to use it, then I would not even consider him to work on your MB.
For the price of this part ($9 with MB Club discount) and the very easy install, it's worth trying before anything else. Dealers stock this part as it frequently goes bad.
Malfunction displayed: "Brake - Visit Workshop".
Car would also not start with Keyless Go, had to insert key.
Car drove & braked fine, but message would appear after every restart.
Problem was: bad brake switch, also called stop switch or brake light switch.
PN: A001-545-40-09 for my 2004, there is one other part number for later years (A001-545-44-09) - verify the correct part with your VIN.
On the online EPC (https://epc.startekinfo.com/epc/)
look under Group 54: Electrical Equipment & Instruments
Subgroup: 640: Switch, #70 on the diagram.
To change this part, remove the black plastic panel above the driver's footwell:
remove 3 torx bolts & pull apart the white large round connector in the middle, then pull panel out, no need to unhook the various electrical connections, just pull the panel part way out.
The black switch is above the brake pedal, along the metal arm of the pedal. If you have the replacement part in hand you will easily see where it is. Unplug the wire connection and then turn the switch 90 degrees to the right to easily remove.
The new one will only go in one way, plug in the wire connector, and replace the black trim panel.
Total time was 9 minutes! Malfunction message gone!
Why pay $100+ at the dealer?
this fixed my "BRAKE - Visit Workshop" message on my 2005 E500. Thank you for posting, it saved me a bunch of money. In 2013, the part is $30.

Driving home from work yesterday and see 'Brake -Service brake Visit Workshop' (NOT in red)
During this same time I think I see one headlamp out (right side)
This morning - Same FSS notification. While driving I noticed my wiper blades would turn on by themselves (when on automatic, but no rain) Then I turned them off - but they still wipe. Also, I see that when I power on my radio my dashboard lights would flicker and wiper blades sometimey. When I use my remote to lock the door I notice not all my headlights would flash. Not the same ones from the 'headlamp issue above'
Other observations
-car breathing harder than usual (doesn't seem to be a high idle though)
1. Any suggestions on a DIY diagnosis? SBC? Brake Switch? something else?
2. Also - is there a website where I can run my vin for any recalls/warranty ???
Good luck!
The "Brake - Visit Workshop" and "Brake Lining Wear - Visit Workshop" are two different errors right? I mean, the second error just came up on my car and I just want to know if this can be fixed with the just the " $10 brake switch" or change the whole pads?

It's not a $10 fix if you got Brake Lining Wear. That means your break pad(s) are worn down and need to be replaced.
The recall that people think or mentioned online is not a true mandatory recall. Dealer and MBZ USA said if you have a problem, then they will fix it within 10 years...
I am shock that this brake safety issue is not a total mandatory recall by MBZ USA, especially if the SBC is designed to cut off the braking capability(without warning) when it reaches 300,000 brake depressions. I am sure MBZ knew of this serious flaw. That is why I was told that this particular brake system was in use for only 3-4 years in the US.
Hope this helps when anyone needs to deal with MBZ USA. Patiently wait and you may get someone to call you back.

The 300.000 break cycles was the point where the motor of the pump or the brake pressure cylinder could malfunction but that was only an issue with version 1.0! Version 1.2 didn't have this issue anymore.
About the 10 years of warranty. I'm on the same side as many others that there should never be an expiration date of it since MB and Bosch which developed the system know about it but at the same time, from a business perspective it makes sense that they capped it. The car is old by now. It was developed in the late 90's and production began in 1999-2000! That's also one of the reasons why many complain about how old and outdated the nav system is today. Sure it was state of the art in dash navigation when it was developed and designed. Not my problem when people by this model 13 years after it was built. Sorry for getting a little of topic!
Anyhow today the warning light went off (bright red) the car nearly shuts down, Brake Failure !! even ESP defective warning, braking is gone. Rolled to a stop, re-started the car and it was OK, drove straight to the dealer, hoping when they open tomorrow, I will get a new SBC on warranty?
