I thought members might find this 'amusing'. I had a SL500, the roof switch started flashing and gonging. I took it to my local MB main dealer. Two days later they phoned me ' We've had it in the workshop , you need a new roof ECU, cost £2300 plus fitting. ' I could not afford this, I bought a second hand one from a breaker ( £370 ) . I took this to MB and they fitted it. It made no difference. I suggested it might not be the ECU. They took the car into the work shop. I watched whilst they loosened 2 bolts, moved a windsceen mounting sideways and the fault was fixed. They charged me £300 for this. Being a 'cautious' type when I first left the car I placed a nut on top of a front wheel under the wheelarch. When I returned 2 days later after their 'workshop examination/testing' the nut was still there. I spoke with their ' customer relations person' she told me ' they must have seen the nut there and put it back for me'... Why would they do this? I later sold the original ECU on Ebay - fitted it on my drive to the buyer's car and it worked ok. I will not name the dealership but I live in Manchester.
