C 240 alarm sounding and fog lights flashing randomly
I called a local MB dealership who told me to bring it in and for $115/hour they will do a diagnostic and explore what is happening. He thought it could be checked in 1 hour but of course, no guarantee. Cost of fixing it depends on the real cause but could range from $115 for wiring issue to over $500 for siren replacement. I don't want to put a lot of money into this car given its age and mileage. I've checked the hood, trunk, windows and doors and all are closed. I opened and closed everything just to make sure.
Please help me to correct this problem! I am fine with not having an alarm if that is the easiest fix.
