I have a 2012 180 c class estate , the problem i have is 2 times now i have got in the car and drove off to notice that the heating is not switched on i have tried turning it on but the panel is just blank , if i stop the car get out and lock it up and come back a few minutes later start the car and all is well again , which makes me think by doing this the car is resetting its self , just wondering if anybody else has had the same problem . The car is due a service in march and the car has still got a warranty so i will ask when i take it in .cheers
