hi, i bought a 2013 c3 1.2 3 months ago and i seem to have a problem with the throttle.
there seems to be a delay, sometimes over a second between touching the throttle and the revs rising, it causes problems when pulling out junctions or hill starts especially when pulling away quickly, anyone else have this problem?
its still under warranty but i cant get to a dealership easily.

Hi steely, it could be the TPS (throttle position sensor) also know as the accelerator pedal. Its a fly by wire system and these have given problems previously with poor acceleration. There is a topic in the Tips section on removing the TPS on an early model C3 here citroen-c3-tips/accelerator-pedal-throt ... t1086.html.

You can diagnose by swapping the pedals over with a known working one, its an easy job. Or diagnose the fault with a cheap OBD2 reader (from here)

It could be totally unrelated, Fiat are having big problems with the 1.2 litre 500s. Something to do with programming the engine to meet emissions spec. Just thought about it with you saying you have a 1.2. On such a new car its hard to imagine that it could be a faulty component but who knows these days.

BBC Watchdog highlighted the Fiat problem, I'm wondering if they share an engine or some of the engine management?
If at first you don't succeed, destroy all the evidence and pretend you never tried :lol:
