BMW x3 DPF issues

[Kimbo5]

Hi all,

My car was due a break fluid service and the engine light appeared so I thought the two were related. It had its service and no issues identified but the engine light was still on, so I took it back to the garage today.

It turns out it is the Diesel particulate filter that is the issue, which is annoying as this has been replaced once already under warranty in Dec 2023 (17k miles) and now has failed again at 32k miles in just over two years.

They have said the Diesel particulate filter only has a two year warranty but for two to fail in just over 4 years is crazy!

Has anyone else had this sort of issue?

Thanks
Kim

You're not doing enough miles to prevent dpf problems at 17k over 2 years. You've got the wrong engine for your use.

Whilst I do fully understand what you are both saying that isn't necessarily true.

Of course that depends on the type/length of journey rather than the annual mileage.

On top of that you have been told the DPF has failed, well has it?

Is it not more likely that there is another issue that is causing the issue as DPFs rarely actually fail. More likely they are the effect caused by other issues. Obviously one of which could be that it never regenerates properly.
