Fault codes 17670 P1262 & 17679 P1271

[R60OEN]

Hi all,

This is on my 1.9tdi T5, it’s had loads of mods and last year new cam kit,new injectors,injector loom etc, Any ideas on these codes, starts first time everytime only issue is when you do a pull in 5th or 6th it’s like it’s misfiring and you have to back off the accelerator and slowly accelerate again, don’t feel as quick anymore either

were the new injectors coded in when installed?

 

[R60OEN]

Yes

What was the reason fro the replacement of the parts last year and when did the faults above occur? - prior to or after the changes?

You might want to do some logging of data of fuel supply info etc. It could be something like a blocked fuel filter as an example.

The parts were fitted maybe 18 months ago, but fault codes came up in the last few weeks, fuel filter was changed at the end of October but still could be that, I will get some logging data and see where it’s at
