Useless

My car has been more at the workshop than I have driven it. After three weeks of purchase engine mountings had to be changed and it is now just over a year old. <br> Of late I have taken the vehicle in for the engine management light which keeps coming on. After having the vehicle for a week, Natasha (the service advisor) and Martin (the senior service advisor) assured me that the problem had been resolved and a week later the light is back on. <br> To my knowledge when this light comes on there's a fault in the engine, well not according to NMI Pinetown since this is the sixth time that the vehicle will be going back to them for the same problem. The technicians should just be honest and say that they don't know what the f.... they are doing.<br> We purchased a Mercedes for safety and reliability but we not so sure anymore<br>
