M340d 3rd time engine light on - DPF sensor

[Mafioso]

Anyone else suffering like me and my father with his? Both of ours have been in twice under warranty for replacement DPF sensors. My engine light has come on again today. It's a 21 plate on 20k miles (he's on about 12k). Admittedly I do a 5 minute commute most days but it gets a good run most weekends. I've had diesels for over 10 years now and never experienced this. Just wondering what to do going forwards as I love the car...?

Thanks for your replies. Do you have any reference to the condensation issues? There is nothing wrong with my DPF - it's just been a faulty sensor replacement every time. Maybe a faulty batch or something?

Have you also had a problem about the gearbox not going into 8th, and only stays in 7th even at higher speed?

No I don't think so. Does it do this if it's doing a regen?

Hi, my 2022 plate had engine management light on which has been diagnosed as dpf sensor fault.
Just drove 500 miles in a day on Friday up north and back so wouldn't think actual dpf could be clogged. Let's see when I get it back. Currently with dealer now.

How did you get on?

My 2022 M340d has just been diagnosed with the same problem. BMW Assist came out and diagnosed it on my driveway, faulty DPF sensor.

Going in to dealer in 2 weeks to have the replacement part fitted.

What sort of driving do you do? I just think this is something that will happen every year with mine...

Mine is mixed driving. 300 miles last Saturday with some bumbling around town during the week. It was the sensor that failed, not a clogged DPF.

Sensor replaced today under warranty. 3 hr job including the wash and hoover

Yep, pretty much exactly the same as me. Lots of pootling around town but plenty of regular long motorway journeys too. never had a problem with any of my other diesel cars (with PDFs)...
