Any merc people. A class window switches..
Evening all, my brother has an 03 reg A class, dont know,what model exactly just yet tho!
Basically he has a problem where the airbag light comes on, so when mot time comes the garage charge him £60 to turn the light off then mot it!
Apparently this has been going on for a few years...
So he asks me if i can turn the light off, i borrowed an OBD2 thingy and was going to have a look,at the weekend as his mot is due again.
I got a call tonight to say not to worry, as on monday his missus opened the drivers side window and it wouldnt go back up so they take it to the garage who strip the door down, get the window back up and charge him £65.
Now they are saying its the switch that is faulty and want £170 to fix it...
After the garage got the window up he was driving the car home and noticed the airbag light was off so booked the car in for mot at the same garage, who said it did come back on but they turned it off (now extra charge this time) and it passed the mot.
So i have just looked on ebay at switch panels and low and behold there is a button to turn the airbag on and off... Coincidence? If its a faulty switch panel can this cause the air bag light to come on?
The garage told him its to do with having child seats in the back, but i think thats bollocks tbh!
How much is a new switch panel from merc? Or is it worth just getting a second hand one?
Sorry for the long winded post!
I have the reg of the car if needed. Cheers!

PassionFord Post Whore!!
My misses's dad has got a 54 plate c class with airbag light issues atm. From what I'm reading across the range it's wiring under passenger front seat or a sensor pad in the seat that can tell if it's a bum or a kids seat...
If I wiggle the wires his light goes out for abit so I'm gonna try repairing the ecu loom first...
Can you not pull the window switch pack apart and clean the contacts up?

I dont know, but from what he says they charge him £60 time to turn the light off, then write out an mot.
Bear in mind that my brother is pretty fucking useless :cry :
Does anyone know if an obd reader will turn off the airbag light before i bugger about with it lol?

Wahay!! I've lost my Virginity!!
Hi mate sorry I can't answer your air bag probs, but my girlfriends old a class use to have a occasional problem with the windows. If the button was pushed fully down for full auto opening it wouldn't work, but as these are a two stage switch if we pushed gently on the button it would work. Hope this helps

Well i took the switch out and tested it with a multi meter and was getting no continuity on the drivers side up switch. Down was ok.
So its deffo the switch. One thing we noticed tho was that the airbag light flickered when you opened or closed the passenger window. So we will see what happens when a new switch is fitted.
He didnt want me to cut off and solder all the plugs tho, said to wait and see if the airbag light comes back on first.
