Hello all,
Special thanks to
Forscan, ForcusMK3, Mishueen for this amazing threat.
I tried the elm327 reader yesterday with my 2012 Grand C-max 1.6 tdci titanium X. The main DTC error codes found are DFP shoot clogging that make the check engine light came up since last couple of weeks.
I successfully resetted all DTC error codes on the dashboard using FORSCAN version 2.1.2 (i will double check later) .
After reset, I also experienced the following (similar to what FocusMK3 already mentioned beginning this thread) :
- The RPM is not stable.
- It was hard to start the engine (sometime I had to start the car 2 or 3 times) especially at cold start.
- The acceleration was not as smooth at before.
- The fuel consumption was very high. 0,7l/h to 0,8l/h when idling.
- it was very noisy, exactly rattling during acceleration and gear changes.
I was thinking of send the car to Ford service ASAP until reading this thread.
Injector learning process:
I decided to start the injector learning values on highway right in the night (23:00) as Mishueen advised and below are results:
After 30 mins, I noticed the better perfomance in every further km

, at the end of the test, here are the findings:
- No error codes in the dashboard.
- The RPM went back to normal condition.
- Start at once like before even at cold start.
- Acceleration was smooth again.
- Fuel consumption went back to normal, maybe better, 0,3 l/h when idling, even better than before 0,4l/h.
Now the only problem is that the dpf problems may be still remained and need to be force regenerated dispite the fact that all DTC error codes was cleared and no faulty code show on the dashboard.
May I ask you to assist:
- Can Forscan confirm if static dpf regeneration function available for 2012 Grand C-max 1.6 tdci available on the latest forscan app? I could not find it anywhere.
- Should I bring the car to Ford for force dpf regeneration. Actually I already bought Wynn's dpf additive which help to burn shoots at lower temperature, should I use it during a long run end of this week or better to wait for the new release of Forscan that support 2012 Grand C-max 1.6 tdci.I am living in France.
- Any suggestion is highly appreciated.
Thank you all again for this amazing instructions and sorry for my bad English that sometimes confusing.
All the best to everyones.
