Posted by Dominic Casey on November 28, 2017, 12:29 pm

Year of Manufacture *: 2014
( Optional ) Engine Code or CC: 1.6 HDI

Hi all,Can anyone give me a bit more information on this code C1391 "Non-Acknowledgement of the engine Torque Fault".ESP light on.Its an automatic,drives ok but I notice it a bit clunky when changing up the gears from rest. Any help would be much appreciated.

Thanks in advance

Have you had a look for faults in the engine ecu, sounds like a torque monitoring fault?

I think you will find this is a robotised manual gearbox,rather than an proper auto shift,that is why it's jerky.As suggested,check engine for faults.Could this be a worn clutch issue?
