“My car is a 2006 mercedes benz SLK280. The srs light indicator turned on and stayed on.. The garage said the cost of repair of the srs system would be over $400.00. I do not know if the restraint system / airbag will work if there is an accident, it may be a very hazardous condition if the mercedes impact protection system is not working. Many other SLK280 owners have also complained about this problem.”
