Thanks for your response. I also have another car which is petrol and "fly by wire" accelerator also. It idles around 7-800rpm. When i (in neutral) press the accelerator extremely gently the revs rise slowly as expected and it is a very linear and smooth response. In the SMAX it idles around the same but pressing the accelerator in the same manner results in no increase in engine revs until a certain point where it just snaps to 2000rpm or above. This symptom would indicate point 1 or 5 above. It is not turbo lag or clutch related as I am in neutral and the car is not moving. I ran the ford garage and they told me to ring the technical number. But at £1 per minute, why should i have to do that on a new car?? Just wondering if anyone else has an 2012 smax and whether it does the same thing.
Hello everyone. I'm new to ford ownership. Bought a pre-reg with 0 miles smax in October. It is 2.0 TDCI zetec. Already had the window motors replaced on the front. Bad start.. Next issue seems to be the non-linear reponse from the accelerator which causes difficulty in taking off from stopped. If i press the accelerator slowly whilst in neutral , there is no reponse from the engine. At a certain point it then jumps straight to around 2000rpm or higher. Why is this? My friend you co-incidently bought the same car seems to have the same problem although i have not tested their car. ECU anomaly? It certainly makes the car hard to drive without either conking out or revving it excessively, Any ideas? Sam.
