M340d 3rd time engine light on - DPF sensor

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...?

A mate lent out one of his cars recently to a friend in need, who appears to have driven similar to you for a month. The day after it was returned, the DPF light came on. BMW fixed it, advised premium diesel/additives help, but won't cure.

That's a journey for an electric car, walking, bike etc. No combustion engine will enjoy that trip, too short, not hot.

True, however they've suffered issues with these sensors, and one of the causes has been through condensation - I thought the new ones had solved the problem. Giving the driving profile, that seems likely to be part of the culprit on continued failures.

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

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.
