Yes, I spoke to the indie, who carried out the last 2 services ( 4&5 ). He advised that the customer would have been made aware of the due transmission service, but as a substantial additional cost, chose not to have it done, and as ive found out, they traded the car in at the end of Sept 23, at the mb dealer, that i purchased from.
My point is , a mercedes dealer , who sold me the car, with a 12 month approved used warranty, should have carried out this transmission service, where as a indie is not obliged to do so, as if selling the cars isn't offering a 12 months mercedes warranty.
