Any thoughts on this fault? "The reason I'm selling is that it has developed a fuel problem which no-one seems certain how to cure. With no real experience of auto-mechanics I'm not in a position to know what is wrong with the car. Therefore the car's stop and start antics have left me with little choice but to sell. The Mercedes specialist garage where I have taken it said they have the following read outs - 008 ELR Actuator Y22 & 002 Speed sensor L3, this may mean something to you guys out there but nothing to me I'm afraid."
