Just small update to my experience with learning process. I was not able to complete this process and due this I have replaced all injectors.
It seems that my injectors were in bad state, this was confirmed by Bosch diesel service. If you see error like Cylinder X Fuel Injector Offset Learning At Max Limit, it can be real issue at your injector.
I had those errors at my 3 injectors, but car was going quite well (6 l/100 km - Ford Mondeo mk4, 1.6 TDCI), only my technician told me that after start at idle, he heard small irregular idle. I recognized this only after his words, but it was really low.

There is one video at youtube about FF3 with same error and technician replace that injector.

Second experience is that after replace my consumption by computer is 4,5l/100 km, which I cannot believe. I will do longer trips and will see.

Hello everyone, i'm new in this forum (i'm from France and own a Focus mk3 titanium 1.6L TDCI 115 2012).
First of all i want to thank the FORScan team for their great job, this scan tool is really good.
Thanks to all users who post and share their experiences and solutions in this forum.

I don't really have issues with my car, it work normaly, but since 1 to 2 mounths i fell some vibrations in cockpit and steering wheel, this happen in idle and when i accelerate.

I performed a scan and got no erreurs at all.

My question is this : can i perform a relearning injection just by following the procedure described in this post or it is obligatory to do a "reset all adaptation" or "Reset pilot injection quantity learned values" before ?

Thank you for your answers.

If there is no error related to injectors, dont do it. You can do injector correction test via computer and physical injector leaking test.
I think if correction are around 1 it is ok.
You can monitor fuel pressure required, real, MAF pressure, if all is fine, it can be something which cannot be monitor by sensors.

Hey there. I'm about to check out a Ford mondeo 2.5 tcdi, 2005 and need some guidance. The owner told me that he has an error regarding the injector on cylinder 1. He changed the injector, now he got a problem with the injector on cylinder 2. By any chance, is this just an error because he might didn't set new values, did a reset or something like that?

Hello all,

I Want share my experience.
I have this error on Ford C-MAX 2011 1.6 85 kW Duratorque. Before engine works pretty fine, no smoke only bad acceleration in low RPM and some fuel leak from fuel return line. I decided to remove all injectors and check them.
I one of workshops test show (cost me 28 Eur), that 3 of 4 injectors are in very bad state, that means low fuel flow in some ranges of RPM reasoned of bad injectors electronic. I decided to buy new ones from Poland dealer. That cost me around 750 Eur with delivery costs. After I replaced injectors (I replaced all the glow plugs at the same time because 2 were bad) and coded them to engine with Forscan and do some ride in hi RPM range, all works fine, when injectors learned, and fuel consumption dropped from 5.6 to 4.4 Ltr/km. So Forscan helped me a lot.

It is unfortunate that the car's PCM does not issue errors to the driver like nozzle and plugs wear.

And I suggest - never try buy old injectors from cars with more then 50000 km run, this is waste of time and money.
And if you have error about injectors learning at high values, i do not recommended reset adaptations, because you can have engine jerking after that, because old worn injectors cannot return to normal working state.
