Question How often, on average, does the V6 DPF regen?

I can't find any info on this, and I there is no definite answer, but last Monday I was in the dealer for a forced regen, and this morning, the DPF symbol came up on the MFD.

I checked the blocks with the VCDS and block 104 shows the milage at 140 km. I hit the highway in S mode, and the DPF indicator went away, so I assume it did a regen.

I've put over 100,000km on the vehicle since I've had it, and i think I have only seen the DPF symbol twice, so I have no idea how often this happens. What is the average mileage people see between regens?

You should never see the DPF symbol, at all, unless you're not driving it enough or long enough to complete a cycle. Mine regens every 400 - 500 miles.

It's possible it's time for a new DPF.

How can i read the soot levels with VCDS?

Here's my readings from this morning, but i'm not sure how to read the values.

Check the Ross-Tech site. I believe it's under 'Advanced Measuring Blocks'.

A regen only happens if it doesn't burn off on its own from extended driving, so there is no answer. You saw the light because it needed to regen and when it tried, you didn't give it enough time. The light warns you to take a nice long trip on the highway before it is too late. Nothing to worry about unless it starts happening frequently or the light doesn't go out after taking a long drive.

Also, I wouldn't replace a DPF unless you have to, and then only after trying to clean it first.

I had all the lights this morning, DPF, and Engine Fault workshop. I quickly read the codes, and there is one for the DPF pressure sensor. I cleared everything, restarted, no warning, drove an hour to work.

So i'll keep an eye on.

The issue is back, and I suspect the DPF pressure sensor, which I had replaced last year. I've since been able to figure out how to do a forced regen.

It may be time to think about gutting the system.

This makes perfect sense however you will technically be breaking the law by doing it. Saying all that you will have a better running, cleaner, more powerful, more fuel efficiant engine as a result. The general public are fleced into thinking DPF is a good thing, they simply aren't but the law is the law sadly.
