VW Amarok Engine Misfire: Common Fixes and Costs

Having issues with my 2021 VW Amarok, the engine is showing classic signs of trouble. When accelerating, it jerks noticeably and seems to lack power. There is also a rough idle, especially when the engine is cold. The check engine light recently came on and stays lit. My mechanic mentioned possible engine misfiring, but I would like to hear from others who have experienced similar problems. Has anyone dealt with combustion misfire issues in their Amarok? What was the actual cause and repair solution in your case? Really interested in what repairs were needed and the costs involved, particularly if it was spark plug related or something more serious.

Having some experience working on VWs, I faced almost identical symptoms with my 2019 VW Atlas. The throttle response was really poor, and the engine had a rough idle combined with clear signs of combustion misfire. After taking it to my regular workshop, they diagnosed the problem using diagnostic equipment. The issue turned out to be a faulty fuel injector that wasnt delivering the correct amount of fuel. The irregular fuel spray pattern was causing inconsistent combustion and the resulting performance issues. The repair involved: Complete diagnosis, Replacing one defective fuel injector, Cleaning the remaining injectors, System reprogramming, Test drive verification Total cost came to 515€ for parts and labor. Since the fix, the engine has been running smoothly with no more misfiring or rough idle issues. Before suggesting specific solutions for your case, could you share: Current mileage on your Amarok? When was the last time you had a fuel system service? Are there any other warning lights besides the check engine light? Does the problem get worse under specific conditions (cold/hot engine, high RPM)? This information would help determine if your issue is similar to what I experienced with the fuel injector system.

My Amarok has 118360km on the clock. Thank you for sharing your detailed experience. My issue does sound very similar to what you described, especially the rough idle and combustion misfire symptoms. After reading your response, I checked with my local workshop again and they confirmed that they need to inspect the ignition coils and spark plugs first. The cylinder misfire seems most pronounced when the engine is cold, which could indicate the fuel injectors need attention too. Did your repair shop mention anything about checking the ignition system before they discovered the faulty injector in your case?

Thanks for providing those additional details about your Amarok. Yes, in my Atlas case, the workshop actually started with a complete ignition system check before identifying the faulty fuel injector. This is a logical first step since cylinder misfire can often be traced to ignition components. When they tested my car, they first inspected all ignition coils and spark plugs because these are common causes for check engine light activation and rough idle conditions. However, after confirming these were functioning correctly, the diagnostic equipment pointed to fuel delivery issues in one specific cylinder. The cold-start symptoms you mentioned are particularly interesting because thats exactly how my engine misfiring issues manifested. The rough idle was always worse during the first few minutes of operation, which is typical for fuel injector problems. A few observations from my experience: At your mileage level, both spark plugs and injectors could be due for attention, Engine misfiring during cold starts often points to fuel system issues, The repair might cost less if caught early before the injector fails completely Based on your description, it seems prudent to follow your workshops suggestion to check the ignition system first, but dont be surprised if they ultimately find fuel injector issues like in my case.

I appreciate the thorough follow-up about your Atlas experience. The similarities between our issues are quite striking, especially regarding the cold-start problems and engine misfiring symptoms. Based on what youve shared, I will have my workshop proceed with their planned ignition system inspection. The fact that they want to check the ignition coils and spark plugs first makes sense as a starting point. Given my Amaroks mileage at 118360km, I agree that both the ignition and fuel system components could be due for maintenance. What really caught my attention was your mention of the cylinder misfire being worse during cold starts. This matches my experience exactly. I think I will also request that they inspect the fuel injectors after checking the ignition system, even if they find issues with the coils or plugs. Better to be thorough and address all potential problems while theyre investigating. Could you tell me how long your repair took once they identified the faulty injector? Im trying to plan accordingly in case I need similar repairs.
