I have been getting an SOS malfunction drive to workshop when it is raining outside? I spoke to my dealer where I service the car and at first they said there was nothing to do and then that it would coast $2k to correct. I have serviced my car there for years and have been happy. I spoke with MBUSA CS and opened up a case. Still not really anywhere. Now they want to diagnosis it for a fee but still lacking direction. Is there any advice on how to correct this issue.

thank you

If this is the SOS Teleaid message, I would look at grounds and antenna, especially if during wet weather

It is a teleaid message - how do I check those things?

If you do not, with the emphasis on you, do not know the location and function of the specific system on your car that may be faulty-----you either do loads of reading and purchasing of tools-------or you pay someone who has the knowledge.

Start with your owners manual. Then spend a couple of weeks searching the internet and then you will understand the problem more fully!!
