Bas/Esp light

Help me !!!!!

My Bas /ESP is still coming on, I've had all my wheel sensors tested and they're fine, my mechanic said my Esp switch isn't working, could this be the problem? The brake light switch was changed at the time of my last post, when the diagnostics was put the car, it came up with a communication failure in relation to the Bas/Esp so its all trial and error ( and manual testing) to find the problem.

can you get the fault codes? was the fault esp/bas relesae switch
what year is the c class ? the esp pressure switch goes on the the 07 onwards c class's give me the codes and il see what it is on my computer
it could be the esp control unit but make sure you check the earths for the esp control unit first

Sadly no I can't, once the diagnostics is put on, it registers a communication failure so I don't know what the codes are, thanks for replying to me, do you have any clue why there is a failure? All the other codes seem to show up ok, the car is a w202 C230k 2000 on a V plate

At last, I've finally got to MB Loughton and had the STAR put on and the stored faults codes ran into 4 pages !!!!

The problem has been narrowed down to a faulty brake light switch (which was replaced with one from MB Stratford in February 2011) or an ESP lateral acceleration sensor, the faults have all been cleared and hopefully no more annoying light.
