VW Taigo Engine Misfires & Power Loss Issues Explained

Had a similar issue with my 2021 VW T-Cross last winter. The symptoms match exactly what you describe, rough idle, jerky acceleration, and reduced power. After seeing the check engine light, I took it to my regular workshop where they diagnosed a faulty fuel injector in cylinder 2. The diagnostic showed the fuel injector was not delivering the correct spray pattern, leading to incomplete combustion and cylinder misfire. They had to replace the injector and recalibrate the fuel injection system. Total cost was 515€ including parts and labor. The repair resolved all issues, smooth idle returned, proper throttle response was restored, and the check engine light went off. These symptoms can indeed point to various issues including ignition coils, but in my case, the fuel injector was the culprit. To provide more specific advice about your situation, could you share: Current mileage on your Taigo, Does the problem occur more when the engine is cold or warm, Have you noticed any unusual fuel consumption, Are there any specific driving conditions when the symptoms get worse, Have you had any diagnostic codes read from the engine computer Your specific answers will help narrow down whether your issue might be similar to what I experienced.

Thanks for the detailed response. My Taigo has 110700km on the clock and I've noticed the engine misfiring gets worse when the engine is warm, especially during highway driving. Fuel consumption has increased by about 2L/100km in the last month. The symptoms match what you described with your T-Cross. Had a combustion misfire code P0302 read at a local parts store, pointing to cylinder 2. That lines up with your fuel injector diagnosis. Will get it checked professionally this week. Has anyone else experienced similar throttle response issues on newer VWs? Hoping the repair cost stays around what you mentioned.

Thanks for those extra details, interesting that your misfire code points to cylinder 2, exactly like my T-Cross issue. The increased fuel consumption and worsening symptoms during warm engine operation are classic signs of a failing fuel injector. Since my repair six months ago, I havent experienced any more combustion misfire issues or throttle response problems. The fuel consumption returned to normal within one tank of fuel after the repair. Just a heads up, while my repair cost was 515€, prices can vary depending on parts availability. The most important part is getting a proper diagnosis, as similar symptoms can come from other components in the fuel delivery system. When they fixed my T-Cross, they tested the fuel pump and fuel pressure as well, just to rule out other potential issues. One tip from my experience: after the fuel injector replacement, I switched to a higher grade fuel for a few tanks and noticed the engine ran even smoother. The workshop explained this can help keep the new injector clean and maintain proper spray patterns longer. Based on your details and the matching error code, sounds like youre dealing with the same issue I had. Please update us on what your workshop finds.

Thanks everyone for the insights. Just got back from the workshop and wanted to close this thread with an update. Turns out it was indeed a faulty fuel injector in cylinder 2, exactly as suggested. The rough idle and engine misfiring symptoms matched perfectly. Total repair came to 490€, slightly less than expected. The mechanic also tested the ignition coils and spark plugs while they had everything apart, all tested fine. They mentioned these components often get checked first when dealing with cylinder misfire issues since theyre common failure points. After the repair, the engine runs perfectly smooth again. No more jerky acceleration or rough idle problems. Fuel consumption has already started improving on my drive home. For anyone searching this thread later with similar symptoms: definitely get the fuel injectors checked if youre experiencing these issues, especially if you get a P0302 code. The repair was straightforward and solved all the problems completely. Thanks again for helping diagnose this, saved me some time and worry knowing others had dealt with the same issue successfully.
