Hi All,

I am brand new to this site (having just registered 15minutes ago). I need some help and I am hoping you can assist me.

Was driving to work this morning and SRS warning lamp went on and stayed on. Contacted a few garages around and the concensus appears to be the passenger seat sensor is faulty and needs replacing. I have the car booked in a diagnostic on Thursday so this will confirm the issue (I hope). The problem I have however is the wide and varying prices that I am being given to repair.

One garage stated 300 euro for the part and then the labour (ouch!) :crybaby2:. the Mercededes Dealership has given me a price of approx 123 Euro for the part and yet there are some forums stating the part can be obtained for a lot less but do not state where. Assuming it is the part that I require, where do I get it other than from suppliers who think I was born yesterday?

Has anyone had similar problems with the SRS warning lamp that is not related to the Passenger Seat Sensor? If so, I would appreciate your suggestions.

Many thanks for taking the time to read this :bowdown:

I had this repair done about 2 years ago and it was related to the seat sensor pad. Repair was done at a local dealership for $690.00 and this was before I knew anything about my car.
Seat sensor pad is part number 2208214751 for mine, check to make sure it works for you as well. Most likely it will. I think this repair involves taking the passenger seat out.
Can be ordered from parts.com for $109.00.
You can search other places with the part number see what comes up.
mbspecialist.com also has it for a higher price.
Good luck.

Here is what I faund for you,

"You mention you have an SRS light that is on? I had an indie MB mechanic show me this trick. Go to radio shack and get some spray electronics parts cleaner with the little straw (about $10.00) With the car not running, spray the cleaner into the two front seatbelt latches then work the seatbelt metal ends in them. Spray inside again and then let them dry about 15 minutes. Apparently dirt gets in the belt latches and there are sensors in them that need to be cleaned occasionally. This is the most common cause of the dreaded SRS light coming one. It may be something else, however this fix is only $10.00.
When you start the car the light should come on for about 5 -10 seconds then go out. I used this method about 1 year ago and it is still working correctly."

Thanks for the quick responses and the information folks. I really appreciate it. I will go to the autoparts shop around the corner and get some spray contact cleaner as a first port of call.

In addition to the seat belt latches, also separate and clean the connector to the passenger side sensor under the seat. Use the same contact cleaner as for the latches.
