My c63 is 8 months old . Been to the dealer with a rattle in the dash . After having it for 2 weeks they told me I was so un lucky because the heater box had not been screwed it properly behind the dash , which by the way they took most of it out to fix this problem . Well 3 weeks has passed and the blinking noise has come back . I'm so angry with mb . They assured me they had foamed it all in and the problem would not come back . Have any other members had this prob . And what do you all think I should do , as I'm proper annoyed with mercs after care service .
