Hi all. I hoping to pull on some genius ideas
I jsut bought a 2017 F-Pace 2.0D. Only to have the EML come on and random misfiring at idle

I have a Lauch diagnostic too and read codes to get

P0263-92 Cylinder 1 contribution/balance
P02CD-32 Cylinder 1 Fule injector offset learning at maximum.

Now initially this looks like an injector issue?
However I found out using car history reporting and speaking to a previous garage that Number 1 injector has been replaced only 400 miles ago.

I there any checks I can do to confirm its failed again OR is something causing this other injector failure?

Just to add. I did also 2 days ago have code P049B-00 EGR insufficient flow. This led me to clean the EGR filter which was fully blocked. this code has not returned.

Is it possible this could just be a heavily carboned up injector

The car has done 99,000 miles

Many thanks in advance

 

Ok. Just to add.

I went and checked injector coding as I had doubts that the last garage coded the new injector.
It is a JLR injector but the coding was wrong.
I read the code off the injector and update the injector coding for cylinder 1 injector.
Cleared codes
The engine start rough like misfiring. So i took for a drive. EML came straight on withing 5 minutes same codes?

Could this be a faulty injector?
OR could it be blocked etc as it was running with the wrong coding and at maximum PCM correction.

Is there any injector relearning you can do?

Many thanks

 

In my experience with these those codes often lead to mechanical engine damage. I would suggest doing a compression test first before you change any more parts.
