Hello I've got a 2004 53 plate clk55 amg and now I have engine light on, I've had the code read and it's p0123 accelerator potentiometer above normal current. Now I am right in thinking this will need a new pedal assembly. I can't find a definitive answer wether my car has just the pedal assembly or a tps under the bonnet, I think it was the w208 that had the tps under the bonnet and mine just has it all on the pedal assembly.
