Erratic engine running and warning light on VW Beetle Diesel 2016: Possible malfunction of the swirl flap control?

Hi, I recently had a similar problem with my 2019 VW Passat Diesel. The car was running funny and the whole car was vibrating at idle, not to mention the unpleasant noise when accelerating. It turned out that it was really due to the swirl flap control on the intake manifold. It wasn't a minor problem, in fact the mechanic said it could have had a serious effect on the engine if I hadn't noticed it in time. He had to replace the whole intake manifold with the swirl flap control and it was definitely not an easy fix. I recommend you have the car checked by a specialist as soon as possible and have the problem fixed. Before you go to the garage, give them a detailed description of your symptoms over the phone so they have an idea of what to expect and can be prepared for your car. I hope this helps you! Regards.

Hi, thanks for your reply and tips! Your experience sounds really similar to my current situation. I hope that the repair won't be as extensive for me. Can you tell me how much you had to pay the mechanic to fix your problem? And have there been any further difficulties since then or is your VW Passat now back in good condition? Kind regards.

Hello, sure, no problem. So, for the repair of the swirl flap actuator, which was electrically defective, I paid €465, which of course wasn't that great, but what's gotta be done, right? Fortunately, it was fixed relatively quickly and since I've been to the mechanic, the problem with the faulty swirl flap control on the intake manifold has also been solved. My Passat is now running like a champ again and hasn't had any more problems since. So, if it really is the same thing, I can only advise you not to hesitate and to have it done as soon as possible. I hope this helps you! Best regards.

Hello, thank you for your frank words and the information. Of course, this is no small sum, but sometimes you have no choice but to bite the bullet to avoid major damage. I'm reassured to hear that you haven't had any further problems since the repair. I will take your advice to heart and make an appointment with the mechanic as soon as possible. I will mention your experience to give them a better idea of my situation. Thanks again for your help and advice! Regards.
