Hello welcome to ww.go-audi.com,

Maybe. It really depends on the condition of your vehicle. Fuel injection services clean naturally forming carbon deposits from the fuel injectors and fuel rails. Fuel injection services can improve fuel efficiency. In truth, most cars don’t need it. The consistent use of quality fuel, and proper vehicle maintenance should be all that is necessary to keep them running properly.

In short, if your fuel efficiency is fine don’t bother with a fuel injection service—Save Your Money!
