Hey, thanks for your answer and help. My BMW is a 1 Series Diesel 2010 and already has 85362 km on the clock. The last time it was in the garage for an inspection, everything was still okay. I have a bit of experience as a mechanic, but I'm not a professional and haven't done much with turbochargers so far. It's awful that you had to pay so much for the repair. I hope it's not that expensive for me, even if I'm a bit worried about the diagnosis. Have you noticed any other problems since the replacement or was the problem solved afterwards?

Hey, thanks for the info! After replacing the turbocharger on my BMW, the car ran like clockwork again. No more black smoke, fuel consumption is back to normal and no hissing or whistling. A defective turbocharger can indeed cause many of your problems. It is also possible that your boost pressure sensor is damaged, but it could also simply be part of the overall problem. What you could do is have the fault memory read out. In many cases, this already contains the solution. In my case, it was the turbo error code. It doesn't cost the earth and can really help you. If it really is the turbocharger, I can tell you from my experience that it's not a cheap repair. But don't worry too much, maybe it's something else with your BMW. All the best, hopefully a cheaper solution can be found for you!

Hi, thanks for the tip about the fault memory. I will definitely have that done. It's good to know that your car ran perfectly again afterwards. I hope it's not that expensive with my BMW, even though I'm preparing myself for the worst. A faulty turbocharger sounds like a pretty expensive affair. But you're right, it could be something else. I'll probably make an appointment at the garage next week and report back then. Thanks again for your advice and support.

According to the Carly readout, it is the boost pressure sensor, but has it already been replaced?
It's a good idea to replace the boost pressure sensor if it's showing up as faulty in the diagnostic readout. However, keep in mind that this might not be the only issue. The symptoms you described could also be related to a faulty turbocharger, as mentioned by LukasFischFan. After replacing the sensor, if the problems persist, I would recommend having a professional mechanic inspect the turbocharger. Please keep us updated on your progress. Do you have any other questions or concerns?

Hello i have this 25D100 massage on carly scanner and drivetrain massage pops up on dash. Is bmw 31d f31 .. how can i fix it?
The error code 25D100 generally relates to a malfunction in the powertrain. This could be due to a variety of issues, such as a faulty sensor, a problem with the fuel system, or an issue with the transmission. I would recommend starting with a full diagnostic scan to pinpoint the exact issue. Once you have more information, you can then decide on the best course of action. Please keep us updated on your progress. Do you have any other questions or concerns?
Hello, I have an E90 330i. I have the following problem: every now and then when I leave an exit, when I'm still rolling and under 1000 rpm in second gear, it chokes. Then the check engine light comes on. After 3-4 days it goes out again automatically. According to the diagnosis, errors 002C7E and 002C7F are present. Lambda control and lambda control 2. Would the fault be rectified if I replaced the lambda sensors or where does the fault come from? Many thanks in advance.

The error codes 002C7E and 002C7F are indeed related to the lambda (oxygen) sensors. These sensors are responsible for measuring the amount of oxygen in your car's exhaust gases. If they're faulty, it can lead to poor fuel economy, rough idling, and a lit check engine light. Replacing the sensors might solve the issue, but it's also possible that there's an underlying problem causing them to fail or provide inaccurate readings. I would suggest checking for any exhaust leaks or issues with the fuel system before replacing the sensors. Please keep us updated on your progress. Do you have any other questions or concerns?
Hey, I had a similar problem with my 2008 BMW 3 Series Diesel. I describe myself as someone with a bit of car mechanic experience. When I noticed something was wrong, I went straight to my authorized garage. They did a full diagnostic test and found that the turbocharger was faulty. Unfortunately, I had to have it replaced, which cost me 1070 euros. Could you give me more details about your car? Such as the exact model or engine power. This may help to better understand your situation and give you further advice.
