Q: What are the steps and considerations for maintaining and replacing fuel injectors on 2015 Audi A3?
A: The injectors wear out during use and generally need reconditioning or renewal after a lot of use and proper testing and calibration with a specialist. When removing, one must be careful to avoid entry of dirt and injector should not be dropped. The same goes with SOHC and DOHC engines which not only require proper refitting and adjustments.
