Thanks for that. Does it need the ECU re-coding though?

Hello, I recently replaced one injector on my Qashkai Tekna J11 1.5. Car ran OK, but fuel ecconomy poor. Month later another injector failed. About to replace.
Can anyone please advise, Does the ECU have to be reset or anything done with it? Thanks.

Thanks a lot. I think i will take your advise.

Hi, could someone please advise what version firmware I can update with and is it worth doing. Keeping it short as not to waste time..
Qashkai Tekna, late 2014
Existing version: D024, Hardware: 031
Can I download the new version online and if so where from?
Thanks in anticipation
