On mine it feels like I'm running low on fuel and the engine is stuttering. The RPMs also judder slightly. As soon as I start accelerating, even lightly, it's gone. In my experience a good way to manifest my problem is by cruising at low speeds (30-50km/h) and just barely feather the accelerator in a lower gear - e.g. 3-4th. No acceleration, just cruising at a consistent speed. I can also let go completely and very lightly press again and it might start doing it. Same happens at higher speeds, but due to the high gear, it's less noticeable. It's worth mentioning that it's not happening every time. Like I previously wrote, it's a bit hit & miss. I have the feeling that it's happening the most when the engine is still not up to temp. I hope this helps.

Hi, I did not have the chance to get my injector replaced yet. I need the car almost every day of the week and it's very difficult to find time for this. I have an appointment for the 26th of May to finally get this done. I also have the exact same condition as described by you. A very noticeable clicking/tapping noise when the engine is cold which then goes away almost completely when the engine warms up. If the car idles for a longer period, the tapping comes back. The engine stutter is still happening from time to time. Some days it's better, some days it's worse. Literally 2 hours ago I came back from the 4th mechanic (break pads needed changing) and he also listened to the noise and confirmed it's the 5th cylinder injector - driver side, middle cylinder. I purchased the new injector last week and the only thing remaining now is to get it installed by someone. We checked the real time values of the return fuel and this injector had almost double the values of the collective baseline at 50+ mg/h I'll provide an update after I get this done.

Hi dude, did you find any solution? I'm having the exact same problem. The electronic actuator for the variable geometry on the small turbo failed last year and I changed both turbos with a refurbished set. Before it went out the engine was stuttering hard, especially when feathering the gas pedal very, very lightly. After the change I even had the workshop clean the entire inlet manifold, throttle body and everything after the EGR pipe, because a friend of mine with the same car (and complaint) told me that this fixed it for him. Unfortunately there was no tangible difference. To make matters worse the refurbished turbo set I bought turned out to be a piece of !Removed! and 2 months later the same damn actuator failed. This time I went to a renowned refurbishing company and my turbo was fully renewed. Again. Like everything except the housing was replaced with brand new parts, including the actuators. After the second time it's now much, much better. Nevertheless, randomly I can still feel it stutter from time to time. It's not nearly as bad as before. At this point I don't think the turbo is the issue anymore, because it's literally brand new, fully tested, balanced, etc. I have a loud injector on the driver's side and at this point I'm wondering whether this might be the culprit here? It feels almost like a misfire, just as you described it. Only happening when lightly feathering the gas pedal. Any ideas or developments on your side?
