Problems with BMW 3 Series (2013) - Black smoke, unstable engine running and possible boost pressure system fault

Hello, I had a similar problem with my 2011 BMW 5 Series. Black smoke, illuminated engine control light, jerking and hissing when accelerating, all this seemed very familiar to me. After I described the problem to my garage, they determined that it was mechanical damage to the turbocharger. The repair cost me 1070 euros. To be able to say more precisely whether it could be the same problem, it would be helpful to know exactly which model you have and whether any repairs have been carried out so far. More details could help me understand the situation better. I hope this helps you!

Hi, thanks for your reply! My model is a 325i and hasn't had any major repairs apart from the usual inspections. What you say makes sense - possibly the turbocharger is the problem. The black smoke and that whistling sound are extremely annoying to me. The 1070 euros for the repair sounds a bit hefty, but if it solves the problem, I'd be reassured. I'll talk to my garage and see if it's the same problem with my car. Many thanks for your helpful input!

Hey, I know that too, maybe I can help with my experience. With the symptoms you've described, it definitely sounds like a problem with the turbocharger. I had the same black smoke and that annoying whistling. And the effects on performance and stability were frustrating too. The repair costs for a turbo are quite high. But I can assure you, once the problem is fixed, you will feel a huge difference. Maybe see if you can get a cheaper used spare part. But try not to put it off for too long. For me, it only got worse over time. All the best and hopefully you'll get it sorted soon!
