Hi all

Got the amber 'Exhaust Filter Nearly Full, see handbook' warning last night while picking up someone up. Wasn't in the position to take it for a blast so i dropped the person off, went home and an hour later took it for a blast on the motorway.

On the way i got the red 'full see dealer' warning, so it went from nearly full to full in a matter of a few miles (quick escalation!). It didn't go into limp mode or anything so decided to crack on.

Within a mile on the motorway in dynamic mode the red light turned to amber and within 10 more miles the amber light went out.

All good and everything, got in my car this morning and no warnings.

The question is, i've had the car 3 months and have never had any warnings, all of a sudden within a couple of hours had an amber and red warning. Anyone know what the thresholds are triggering these warnings? Because i took it for a good run would that have cleared it 100% or just down to below the threshold? I've got the gap tool, is there any way to check with that?

Sorry its long winded, thanks in advance! L494 3.0L SDV6 Autobiography in Chile Red (Current)

Just come across this thread https://www.fullfatrr.com/forum/topic48068.html which is an excellent write up, loads of information. L494 3.0L SDV6 Autobiography in Chile Red (Current)

I was reading through your post and was going to link to the exact thread that you've found in the mean time - it's an excellent thread!

Do you have a GAP IID tool? They're very useful for monitoring the situation.

Funnily enough I found that thread last week, and did a check on my soot levels.
Bearing in mind I've never had a DPF warning (amber or red), this is what I had:

First check - 15g. Most popular journeys I do is 16miles before returning an hour later, approx 75% fast A road/dual carriageway.

Second check - 17.5g. I had just driven 45 miles, 50/50 split between fast A road and motorway.

Third check - 5g. The same return journey later in the day.


Quite interesting, I've had the car for 3 years so assume my driving is generally deemed suitable for the DPF.

Sure - I had to update mine to the latest version first, I initially didn't have the option.

Then go to Live Values -> Select Live Values -> All

Then in the search box type in soot, and select "Diesel particulate filter soot concentration - Inferred using differential pressure"

Then view that and it will give you the reading. It's in the Engine section if you need to find it manually, I think. MY16 RRS 3.0 SDV6 HSE Dynamic

Excellent, thanks i'll give it a go on my way home L494 3.0L SDV6 Autobiography in Chile Red (Current)

I dont have an IID tool - yet, does anyone know if you can monitor the DPF soot levels using snap on solus pro or Launch diagnostics, as I can get access to these.

Hi Pete, have a look at this video on YouTube...

Yes that'll be in g. A regen is triggered at 17g I believe, but you need to have at least 1/4 tank of fuel and a speed of over 50mph - obviously the longer the better.

Fulfil those criteria on your next journey and the soot level should decrease!

What things are you finding that don't work? To be honest I've only used it for specific things I needed to do, and it's worked for all of those. MY16 RRS 3.0 SDV6 HSE Dynamic

I can't remember specifically, just tried playing around with exhaust gas temps etc. Seems whatever i tried the reported value was always N/A.

Its only the inferred soot level seems to work. L494 3.0L SDV6 Autobiography in Chile Red (Current)
