I have an 09 A5 S-Line with the 3.2L engine with just under 50K miles on it. Should I consider doing a fuel injector cleaning service on it? I've heard both sides of the argument and would like to hear from fellow Audi enthusiasts what their take is on the subject. I'm inclined to do it assuming there is some value in it. My fuel economy is normal (no change from new) and there is no abnormal indications. I use the recommended octane ratings from top tier fuel vendors (BP, Shell, etc...).
Bottom line: have it done or no?

 

If it aint' broke, what are you trying to improve?

 

Just considering it as a preventive measure. It may not improve anything initially but it may (emphasis on may) allow for longevity. This is why I'm asking the question. As I indicated, I'm on the fence.

 

If your A5 is running smoothly with no drop in performance or fuel economy, you don’t need a fuel injector cleaning yet. At 50K miles and using top-tier fuel, the injectors are likely still clean. Most owners only do a professional cleaning if they notice rough idling, hesitation, or poor fuel economy. For now, you can skip the service and just keep using quality fuel and performing regular maintenance.
