T-Roc Fuel Injection Troubles Hit Performance and MPG

Had similar symptoms on a 2020 VW Golf TSI gasoline engine. The performance issues started exactly the same way, rough idle, weak acceleration, and increased fuel consumption. After diagnosis, it turned out the fuel injectors were severely clogged, causing inconsistent fuel delivery and unusual misfires. The repair involved removing and ultrasonic cleaning of all injectors, plus replacing two that were beyond salvage. This was quite a serious issue since dirty injectors can lead to complete engine failure if left untreated. The vehicle emissions were also affected, as shown by higher than normal exhaust readings during testing. The symptoms improved dramatically after the repair, smooth idle returned, power delivery became consistent, and fuel economy went back to normal. Worth noting that modern direct injection systems are quite sensitive to fuel quality and maintenance intervals. Regular fuel system cleaning service is recommended every 60000km to prevent similar issues. Using quality fuel and keeping up with maintenance schedules helps avoid these problems.

Thanks for sharing your experience with the Golf injector repair. My T-Roc is showing almost identical symptoms, really concerning to hear it could lead to engine failure if ignored. Did the garage mention if any other components needed attention during the repair work? Would be helpful to know the repair cost in your case to budget accordingly. My vehicle is running especially rough during cold starts and seems to be getting worse each week.

Following my initial reply about the Golf TSI issues, I got the injection system fixed last week. The mechanic found one injection nozzle defective and had to do a complete clean of the injection system. The repair resolved all the cold start problems and rough running symptoms I mentioned earlier. The total repair cost came to 515€, which included the replacement of the faulty injector, cleaning service, and diagnostic work. The vehicle runs perfectly now with smooth acceleration and normal fuel consumption. No other engine components needed attention during the repair. Regular maintenance and quality fuel really do make a difference in preventing these emissions and performance issues. For your T-Roc showing similar symptoms, getting it checked soon would be wise to avoid potential engine damage. The repair cost might vary but at least you have a reference point now. The improvement in performance after fixing the injection valve was dramatic, no more rough starts or hesitation during acceleration. Looking back, addressing the problem early was definitely the right choice.

After dealing with those worrying symptoms, I finally took my T-Roc to a specialist workshop last week. Just like in your case, they diagnosed clogged injectors causing the poor performance and rough running. The repair included a thorough fuel system cleaning and replacement of one completely blocked injector. The total bill came to 490€ including parts and labor. The engine now runs perfectly, no more cold start issues or hesitation. Fuel consumption has returned to normal levels and the power feels strong again. Was definitely worth getting it fixed before causing more serious engine damage. The emissions test they performed showed everything is now back within normal range. The mechanic also recommended using higher quality fuel going forward to prevent future clogging. Will definitely stick to regular maintenance intervals from now on. Really appreciate your advice about addressing this early. The repair experience was much better than my previous garage visits and the results speak for themselves.
