My 02 E46 330 has a notchy action to the electronic accelerator pedal linkage making smooth starts difficult and driving unpleasant. The action is just the same with the engine switched off . Lubricating the linkage from the outside (through the rubber grommet) makes it more progressive but I'm sure this sort of intervention should not be necessary. It seems there is something mechanically wrong in the module or additional lubrication required. Security torx screws prevent access to it.
At the dealer someone tried the car, said it was "OK" and that a new module would be £120+VAT fitted.
Anyone else had the problem? Can I cause damage using lubricants? Is a new module the answer?
