Audi Q5 Fuel Injection Issues and Repair Guide

I had very similar issues with my 2011 Audi Q7 3.0 TFSI last year. As someone with some experience working on Audis, these symptoms immediately pointed to clogging in the fuel injection system. The engine performance was seriously compromised, rough idle, excessive fuel consumption, and significant power loss. The emissions were also notably worse, producing more smoke than usual. After taking it to a workshop, they performed a complete fuel system diagnosis including: Injection pressure testing, Fuel delivery rate measurement, Injector spray pattern analysis The repair involved: Professional cleaning of all injectors, Replacement of 2 completely clogged injectors, Full system flush Total cost was 515 Euro, which included parts, labor, and diagnostic fees. The repair completely resolved all symptoms, the engine runs smooth now with restored performance and normal fuel consumption. Before suggesting specific solutions for your Q5, could you share: Current mileage, Fuel type usually used, When was the last fuel filter change, Check engine light status, Any recent fuel system maintenance This information would help determine if your issue matches what I experienced and whether you might need similar repairs.

Thanks for sharing your experience. I am at 48807 KM and my last service was just 2 months ago when they performed routine maintenance. What concerns me is that my gasoline engine issues started right after the service. The engine power loss and rough idle you described match exactly what I am experiencing. I think I will need to get those injection tests done. Did you notice any improvement in fuel consumption after the repair? Also wondering if there are any preventive steps to avoid injector clogging in the future.

Thanks for those details. After my injection system repair on my Q7, the fuel consumption dropped significantly, back to normal factory specs. My vehicle was drinking about 25% more fuel before the fix, which was a clear sign of the injection system problems. Regarding your situation starting after service, this raises a red flag. Sometimes low quality gasoline or contaminated fuel can cause rapid injector deterioration. Since the timing matches your recent service, it would be worth checking if: The fuel filter was properly installed, The correct grade of gasoline is being used, Any water contamination in the fuel system To prevent future injector clogging, I now: Use only high quality fuel from reputable stations, Add fuel system cleaner every 10000 km, Change fuel filters according to schedule, Avoid running the tank too low The misfire symptoms you described are classic signs of injector problems. The complete diagnosis process took about 2 hours in my case, and the improvement was immediate once fixed. Each injection nozzle replacement made a noticeable difference in how the engine ran. Based on your low mileage, I would definitely get this checked soon before it potentially causes more extensive engine damage.

Thanks for the detailed suggestions. Your experience really helps put things in perspective. Since my vehicle has such low mileage, I will schedule those injection tests this week. The fuel consumption issue is definitely concerning, I am getting about 30% worse efficiency than normal, even worse than what you experienced with your engine. I checked my service records and noticed they did replace the fuel filter during the last maintenance. Given the timing of when these issues started, I will have them verify the installation. The gasoline quality could indeed be a factor since I recently switched to a different fuel station to save money. I appreciate the prevention tips. Will definitely start using better quality fuel and add those recommended cleaners to protect the injection system. The last thing I need is serious engine damage from trying to save a few Euro at the pump. Will update once I get the diagnostic results and repair completed.
