I had to tow my Range Rover to the Dealer the day before yesterday, and the Dealer says that the whole BECM needs to be replaced. I wonder why??? because the car was just fine when I left it at the airport, and now just to synchronize the key with the car, the dealer says that the whole BECM needs to be replaced!!! This just doesn't make any sense to me! Moreover, I checked it online, and a used BECM is for about $500 with three year warranty, however, the dealer says that he cannot install that part in the car, and the BeCM has to be a new one and he's charging me $2600 for it!!! Any one any advice??? Please!!!!
