Diesel BMW 3 Series model year 2014: Exhaust back pressure sensor defect and other symptoms

Dear community, I was a little worried about my old 2014 diesel BMW 3 Series with a whole bunch of kilometers (219340 km to be exact). The good old friend has been showing some strange symptoms recently. The thing is, it puffs black smoke out of the exhaust when I accelerate, and the check engine light is permanently on. The engine's performance drops, the engine runs irregularly and the DPF regeneration no longer works properly either. The fuel consumption is also quite high. I assume it has something to do with the exhaust back pressure sensor on the diesel particulate filter. I wanted to ask if anyone has ever had something similar with their car? What experiences have you had with the workshops? I had really bad luck with my garage last time! Thanks in advance for your help! Regards

Hey, that does sound like a serious problem. I have a diesel BMW 1 Series built in 2017 and had similar problems with my car. In the end, the DPF regeneration and the exhaust back pressure sensor had to be repaired. Like you, my car also had the check engine light on and the engine was running erratically. I think you're right in your assumption about the diesel particulate filter. Have it checked at the garage. I know how annoying it can be with garages, but hopefully you'll have better luck this time! Good luck! Best regards

Hey, thanks for your super quick reply! Sounds like we went through almost the same situation. That calms me down a bit now. Was a repair like this on your diesel BMW 1 Series very expensive? And how have things gone for you since the repair, has anything else come up or was the problem fixed afterwards? Thank you! Regards

Hey, yes, it looks like our cars have similar quirks. The repair on my diesel BMW 1 Series was unfortunately not cheap, it cost exactly €1325 because the DPF was heavily loaded. But since I repaired the exhaust back pressure sensor on my diesel particulate filter, my car has been running like new. Everything has been working perfectly since I went to the mechanic. No additional problems or anything. So I can only emphasize how important it is to have it checked, even if it costs money. Good luck and hope everything goes well with your car! Regards

Hey, wow, that sounds like a lot of money, but I agree that it's necessary to look at it carefully. 1325.00 might be the cost I need to pay now so I don't have even higher costs later. I'm glad to hear your car is running like new again after the repair! I'll take your advice and make an appointment at the garage as soon as possible. Hopefully I'll have better luck with the garage this time. Thank you for your advice and encouragement. Wish you many more carefree kilometers with your BMW! Regards

Hello, if you google "BMW ETK" there are many BMW dealers where you can find the spare parts directly.

Hi Benny! Can I trust the articles in the online BMW-ETK?

Good evening! I have a problem with my Bmw 3 series (2008 e91) 318D 143cv. The engine light comes on and the car loses power and won't start. After a short time it switches off and the car starts again. It no longer has FAP and EGR and the mechanic says the turbo is fine. This happens a lot when I'm going at 130/140 km/h because at low speeds it doesn't come on. What could it be?

Hello, Do you have an error in the error memory? This would help us to narrow down the error further.
