UK Ford Repair Questions? Ask a Mechanic for Answers ASAP
Hi my name is ***** ***** I will be happy to assist with this today.In some cases I may need more info to assist better.I apologize for any delay.
The red triangle light is to let you know that the engine computer has detected a fault.This is the engine malfunction indicator lamp.What most likely occurred is a fault occurred causing the triangle and the loss of power.Then when you switched off the engine and restarted the fault was no longer present and the light stayed off and power resumed.The computer then cleared out the code itself and this is why no codes were detected when you took it in for diagnosis.
This can be a large number of different components at fault that caused this issue here.The only way to know for sure what was acting up is if it comes on again to have the computer/scan tool plugged back into the vehicle right away to see what codes are set.
I have seen issues with the DPF (diesel particulate filter) cause this issue here needing cleaned or replaced.
