BAS/ESP light
Re: BAS/ESP light
The switch came in at lunch and I installed it. So far so good with a long spin around the block. Time will tell...
I took the original apart and found that one contact point was looking bad. This contact is closed when your foot is off the brake. When I get time, I am going to look over the wiring diagram.

The last one I put lasted almost two years. There is no underlying problem I am not fixing. Some people in the Mercedes forums have to change the brake light switch every year too. Every Mercedes dealership carries it in stock because it is such a common issue.

The iCarsoft MB II worked for me a few months ago and it said the stop lamp was inoperable. The weird thing was the code was read from the transmission module if I am not mistaken.

When I replied it was like 5am my time. To clarify my first one lasted 7 years and went out right after my extended warranty expired. Since then I had to replace it about every year with the last one lasting about two years.
Re: BAS/ESP light
One time I replaced it with a Chrysler one and it didn't come from Mercedes and it lasted the least amount of time. I think it is just one of those gremlins on certain cars and other cars never have this issue.

😉 I think mine was built on a Wednesday haha! Assembly line was over their hangover and looking forward to their next one.
Re: BAS/ESP light
Hey everyone ....so lm having the dreaded BAS light stay on .....so background .....stored car for the winter ....no issues no lights before storage ..so l did let the battery run down low before l noticed it , charged up and put battery tender on ...just took car out BAS LIGHT stayed on and brake pedal spongy...tryed reset with steering wheel left and right ....light still on.... shut engine off restart light off but after 2-3 brake applications comes back on ...tires pressures checked -ok ....brake lights ok.... Brake fluid level ok ..... nothing happened to cause this other than battery was almost flat.... ld almost be leaning towards replacing the master maybe trying to bleed brakes before hand ....what do you think ??
Re: BAS/ESP light
James lm unclear what your saying? Bleeding brakes works temporary, master is perminant fix ...that covers the spongy pedal l get that ....brake light switch repaired the BAS LIGHT .....so your saying that they are TWO different problems. ...l thought fixing the spongy pedal would solve both problems
