My friends car is bringing up 2 throttle pedal codes (which wont clear on the snapon solus scanner) and a cam shaft hall sensor code, which does clear but keeps coming back, after cranking, with no start, sometimes the car fires/splutters but will not run.

Ive fitted a new camshaft sensor, which worked for a short while but now the car wont start again, so i decided to fit another throttle pedal, which turned up today (21/05/18) but this has made no difference, so, now i'm a bit stumped the only code that i thought would affect the starting, would be the cam shaft sensor or the crankshaft position sensor but there is no ckps code.

any suggestions are welcome and appreciated, i'm a mechanic but have limited knowledge on Mercedes.

Thanks Dave

p.s I'll list the codes, when i get a chance to plug the scanner in again.

The glow plug code and camshaft codes can be cleared but I’m unable to clear the accelerator pedal codes.
