The code that came up on the car but not on the OBD2 Reader was C41668

This is a desiel Mondeo 2008

Copied this from a Ford owners forum :

C41668 = U0416-68
U0416 = Invalid Data Received From Vehicle Dynamics Control Module U0416 = Invalid Data Received From Vehicle Dynamics Control Module
68 = DTC Failure Subtype definition for failure category “6”. 68 = DTC Failure Subtype definition for failure category "6". Event information — This subtype is used by the control module to indicate the detection of a system event that was not caused by the control module itself but forces the control module to store a DTC (eg missing functionality from another system/control module).

Sounds like an ABS or Stability control fault ? This could, in some cases cause the engine ECU to reduce power (not unlike limp mode) as it gets a false reading from the ABS saying the car is skidding even though it's not, and is trying to control it ?

Best advice is seek professional help and get the errors diagnosed correctly. The car will still stop without ABS but if it loses power when your overtaking, that's a different matter.
