Speed reverse error

[heshamderbala]

Hi
Could you please tell me what causes the error of engine fault appears and disappears immediately if iam at revers and press the speed pedal hard suddenly but the error doesnt appear if i press normally and this happend in reverse only whether in flat land or hill

It is difficult to diagnose without more information. At least tell us what model of car! There may be a stored fault code.

It may be because the engine speed is limited whilst in reverse gear - by design to protect the gearbox. However if you do have a fault code it may help and clarification that this is in relation to your DS7.
