Hi guys,

I am the new happy owner of a bmw X4 F26 2015 3.0d 190kw 258ps. After reading some values in ista+ I've discovered that the correction values on one of the injectors is outside the permitted limits on cylinder 2. My question is, can/should this be corrected? Or does this injector really need replacing? Please find attached the photos.

Just to mention, when doing the smooth running control test, all injectors were om green zone, the idle of car is still, no problems at all. Much appreciated https://i.postimg.cc/NfywrTrh/20250408-090502.jpg https://i.postimg.cc/JzZVpLqP/20250408-091101.jpg

Welcome to the Forum

The smooth running test tells you more, if idle is smooth and raising revs and letting them fall back doesn't upset the smooth running test all should be OK. Injector values are easy to reset but to do it you need the numbers on the top of each injector and that will need access to the injectors.

Personally if things are running well MPG and Performance where you would expect I would leave it and monitor it once a month or so

Enjoy your Beemer

Hi Dave,

It appears that my Ista+ was out of date and the idrive(ecu) software in the vehicle is running the 2018 version, therefore, reading the vehicle with the up to date remote ista from the dealership  shows there is nothing wrong with the car. It's already booked for a software update with the 2025 version

Thanks!
