Well , having purchased my first Mercedes, I unfortunately found this forum as a result of the breakdowns I experienced within my first five months of ownership. I've already listed like most of you, my injector tale of woe. I have read with interest the varying response of Mercedes to each of your cases and I agree with some who say the vehicle still gives immense pleasure when running but the company has somewhat sullied its fine name with the patchwork quilt response to our various breakdowns ,all traced back firmly to their manufacturing process , be it third party or not. I have never ranted or thrown my 'teddy out' despite feeling like I should , but I must agree I am less than amused with how I have been treated. My car is fixed and God willing appears to be running well. I politely enquired about any form of recompense be it in the form of a free service or whatever they deemed fit, just to acknowledge they are empathising with their customers. The dealer said not for them to do, so I reluctantly sent an email to Mercedes customer services and I have today received a phone call and email offering me £250 pounds towards a standard service within the next 24 months. This I feel is an acknowledgement of sorts and now I hope your motoring as well as mine will be trouble free. Good luck to all and sunder!
