Check engine light and loss of power in the VW Arteon Diesel 2019: experiences with the boost pressure regulator problem

Hey guys, I have a strange problem with my VW Arteon Diesel, year 2019. The check engine light is on, I notice a loss of power, the engine is restless and the car jerks when accelerating. Have any of you ever had the same problem with the boost pressure regulator? How did you get the problem solved in the workshop and what were your experiences? Many thanks in advance!

Summary of the thread

A 2019 VW Arteon Diesel is experiencing issues with the check engine light, loss of power, restless engine, and jerking during acceleration. A similar problem in a VW Passat was resolved by replacing the turbocharger, suggesting that the boost pressure regulator or turbocharger might be the cause. It is recommended to have the vehicle checked at a garage, focusing on these components, with the hope that only a minor part needs replacement.

Hey, I actually had a similar problem with my VW Passat, model year 2017. So I have mediocre experience of cars, I'm just not a professional. At my garage, they said it was the turbocharger. They replaced the thing and lo and behold, problem solved. The whole thing cost me a whopping 1700 euros. But now the engine runs like the first day. But I can help you better if you tell me a bit more about your car. Are there any specific symptoms or events that occurred before the problem?

Hey, thanks for the quick response. First of all about the car: Just had the full service 24900 km ago, so everything is tip-top. There was no specific event before this problem, it came out of nowhere so to speak. The engine just doesn't feel right any more, and the jerking when accelerating is really unpleasant. But it's good to hear that changing the turbocharger has helped you. I'll take it to the workshop.

Hey, no problem, I'm happy to pass on my experience. Based on my experience with the Passat, I would say that it is quite possible that the boost pressure regulator or the turbocharger is the cause of the problem. It was exactly the same with my Passat: jerking when accelerating, uneven engine running and the check engine light came on. After the turbocharger was replaced, everything was as good as new again. It sounds like your Arteon has similar symptoms to my Passat back then. Have it checked at the garage and tell them to check the turbocharger/charging pressure regulator. Maybe you'll be lucky and it's just a small part that needs replacing and not the whole turbocharger like mine. So I'll keep my fingers crossed that you don't have to pay as much as I did. Let me know how it goes!

Hey, thanks so much for your assessment and encouraging words! You've definitely answered some of my questions. I'll bring this up when I visit the garage. Hopefully it's not quite as serious as it was with your Passat. In any case, it's reassuring to hear from someone who has had similar experiences. Have a good trip with your Passat. I'll definitely be in touch to let you know how things turn out!
