Problems with engine performance and DPF regeneration in a 2016 BMW X5 - suspected defect in the exhaust gas temperature sensor

Hey, thanks for the quick reply! Good to hear that it doesn't look too serious. Do you happen to remember an approximate price you paid to replace the sensor? Does it solve the problem completely or have other things popped up since then? Thank you!

Moin, after the repair in the workshop, the problem with the defective exhaust gas temperature sensor in my car was fortunately completely resolved and has not reappeared since. The repair cost €95.00 because the sensor plug was defective. Take it easy, you can fix it!

Hey, first of all I would like to thank you all for all the helpful information! In fact, I went to the mechanic and they confirmed the fault. It was the exhaust temperature sensor that was broken and needed to be replaced. Surprisingly, I even had to pay a little less, just under €90. So, all in all, it was worth having it checked and I'm glad that it could be repaired comparatively cheaply and quickly. Thanks again to everyone! You have helped me a lot to keep the costs down and overcome the lack of knowledge about it. Best regards to you all!

Hi BMW drivers, With my diesel BMW, which had the same problems, it was the thermostat on the engine. It could simply build up the necessary temperature for regeneration. That's how the mechanic explained it to me.

Hello, my BMW E60 M5 has a different sports manifold from super Sprint. The lambda probe plugs are free, so I have a completely different smell in the exhaust that is too extreme for me. Why could it be

(Translated from German)

It sounds like the lambda (oxygen) sensors aren't connected. These sensors are crucial for managing the fuel-air mixture in your engine. If they're not connected, your engine could be running too rich, which would explain the strong exhaust smell. I'd recommend getting those sensors connected as soon as possible. Running too rich for too long can cause damage to your engine and catalytic converter. Please let us know how it goes.

The error always occurs when I drive the car above 210 km/h, as it is actually locked.

Driving at such high speeds can put a lot of strain on your vehicle's engine and other components. The error could be due to a variety of issues, such as overheating, fuel delivery problems, or even transmission issues. It's hard to pinpoint the exact cause without more information. I would recommend having your vehicle inspected by a professional mechanic to ensure it's safe to drive at these speeds. Please keep us updated on the situation.
