Car is a 2011 530d. 144k miles. The car is regularly serviced by BMW independent.

Mainly used for longer journeys, not many short town trips. Car is healthy and at the last service the BMW independent said it drove very well.

Using the Carly scanner it tells me the DPF is in a bad way and getting close to being blocked.
No warning lights showing.
Exhaust is sooty on the tailpipe.
No mpg issues. No performance issues.

Carly readings are 5.25g soot. 46.86 g ash.

A local mobile DPF cleaning service has loads of positive reviews. Should I get it cleaned or keep the money in the
bank. If it ain't broke don't fix it?

I'd check/change the thermostats first. Is carly showing its still regenerating as it should?

Agree ^^^

IMO sounds like your engine isn't getting up to temps...

New stats and give it a good run / force regen etc

I know a lot of people turn their noses up at additives however on two cars with similar issues I have had a lot of success using
Archoil AR6400 D-Max.

If you do have issues preventing the car from regenerating correctly it’s not good to fix those problems however my experience has been really positive so for the sake of £30 or so, it could be worth a try.

I think at that mileage I would get it cleaned. Leaving it, runs the risk of taking out the turbo, with the back pressure. I would also check the thermostat as another person has said.

My understanding is that the x30d engine runs forever if serviced properly, and that the DPFs are not an issue if at the correct temperature.

On that basis, I would +1 the comments above re: checking/replacing the thermostats to ensure it is operating at the correct temperature.

Looks like i will be getting it cleaned.

The 'secret' menu shows that it gets up to the proper temperature easy enough.

Thanks for the input everybody.

Maybe ask for a second opinion (from the independent garage?) to see if it matches the Carly scanner before committing money to a clean.

Following this thread with interest!

After EGR air flow issues with my F30 320d I invested in the Bimmerlink app to monitor future engine lights etc. I've always been curious about DPF regens (Apart from a small handfuls of times the engine fans keep running after switch off, I've never been aware when the car is doing a regen) and the condition of the DPF. My commute to work is only 12.5 miles and I don't often do long trips, however, I haven't been aware of any issues with the DPF over the 6.5 years and +-70k miles I've owned the car.

Reading from Bimmerlink below, looking at the OP's stats I'm wondering if my DPF is starting to get clogged? I don't use the 320 much now as I've got an i3 for running about but the last two weekends I've done a couple of longish trips (an hour's driving each way, generally at motorway speeds) and both times the car has done a regen, approx 100miles between each one. What do you all reckon? Readings taken when engine not running.
