System too lean bank two
Sounds like an o2 sensor on the drivers side theres and upper and lower o2 sesnor they go for about 100 bucks on parts geek.
SOURCE: check engine code -- lean bank code
If that's the only code, it's likely the primary O2 sensor (before the catalytic converter). That's the one that determines the fuel mixture.
SOURCE: system is running to lean on bank one
As it says just one bank I would suspect possibly an injector or lambda. In Vagcom you can do a lambda load test, I suggest you do this as it individually does each lambda sensor to check it.
Check your injectors as well.
Hope this helps; also keep in mind that your feedback is important and I'll appreciate
your time and consideration if you leave some testimonial comment about
this answer.
Thank you for using Fixya, and have a nice day.
