I understand Pete’s desire to understand the procedure.
I am exactly the same and put it down to my engineering brain being trained to work out how things work so I know how to fix anything when it breaks .

I don't fret or worry about cars, just nice to know what makes them tick... everything is repairable, some faults just cost more knuckles than others....

Inlet hoses are on the list, pretty near the top as well....  Pete

Get a supply of disposable gloves because you are about to discover just how dirty modern diesels really are.
Also clean the MAPT sensor whilst you have the bonnet up. It’s a five minute job, but a well known cause of R.P. bongs when clogged up.

HI Pete,

I bought my 2012 4.4 TDV8 vogue in oct 2021 with 160000 km and supposedly nothing to do, from a reseller.
took a warranty though
since I had the oil filter radiator (a classic gasket failure), a rear air suspension replacement (right) and a recent (170000km) DIRECT TO RED ALERT limp mode "DPF filter full" EGR failure (that did cost me 3500 Euros, half of which was under warranty).
I'm like you I didn't know I had to monitor anything.
Now I plan a 1/2h highway run every week or so... "When in Doubt, Do Something"
AND I'll get an ODBII reader... any recommendation for the brand and model ?

Cheers

There will always be something to do, I regularly try out all areas of the rev range to give my cars the exercise they need... use it or lose it as they say....

I've always had the Gap IID tool, I find it does everything you want and a lot more besides, plus it's small and fits in the glove box no bother...

I'm reading all I can about the diesel to give me some understanding of how it works so I can, hopefully, get to the bottom of any issues...  Pete

my experience, was when I bought mine, as I left Birmingham to drive it to London, I got a red DPF alarm, (D'oh!) just as I was leaving the city, which on the motorway, I found I had restricted speed, around 50mph, and no real power. BUT after a 30 mile drive, I stopped, and after that it was driving fine. so it sort of fixed itself, a little. which goes against handbook theory. since then, and frequent dual carriageway and motorway drives, it never flagged anything up. however, about 8 months on, I got a yellow alarm, and that was in central London, and heavy traffic. and within 10 mins of idling, it went red. which I was annoyed about, as that is sort of 'don't drive it, get it to dealers'. so I got it home, again with a lack of power... and read the soot levels on the IID, I was now at 32grams. I had a code fault on my manifold, 'p0040d' which was not allowing 'on the road' type regens. (sensor was testing open circuit) so even with contstant cruising, it was sooting up. somewhat. anyway, I couldn't get the sensor out, as the nut broke off, and unable to get the new sensor to ever get hot...so had to make it think it had a hot temp, (sensor) with a DIY resistor. (650 ohms) I then took it out for a motorway cruise, and with the Iid tool, under service/test page, you can force a regen. you will see that the speed only needs to be 25mph, (reading goes from red to green) and temp at normal, and more than 1/4 tank of fuel. you can also see the soot level, and after about 15-20 mins, at about 40-50 mph, so I never hit any bunching traffic, it started to fall quite fast. and after a further 15 mins, was at around 0.3 gram. I then pulled off, stopped car, and dash warning was clear. car was perfect. left the resistor in, and car seems fine now, as can complete passive 'on the road' regens. p.s. you do not do Italian tune-up type 'thrash' driving, you need low revving cruise. I think you just need air blowing under the car, to stop the DPF overheating, whilst it cremates the soot.
note, each regen has an effect on the oil in the engine (so I understand) as some diesel fuel is introduced? so you have a page on the IID to monitor oil condition. interesting stuff. the IID tool read logs, that will tell you how many regens have ever happened, there will be hundreds of incomplete ones, and a handful of completed ones. (if its like mine, at 200k)

John, thanks for that, I read your other posts about your sensor issue, very interesting and informative, I wasn't saying an Italian tune up is good for regens, it's good to keep things working and exercised in general...

The driving I do these days seams to be just what this engine needs, a mixture of roads from B roads to M roads... hopefully that will be good enough...  Pete

Never work mine hard and can go for months without going over 2krpm or activating the 2nd stage turbo. Never do short trips and only use it for long drives. Every time you apply the power unnecessarily it's straining components and shortening their life.
 2012 TDV8 Vogue (L322)

Well we will have to agree to disagree. I firmly believe in exercising a vehicle to it's parameters as long as it is well serviced and thoroughly warm. Certainly not thrashing it and not all the time but using the vehicle to it's full extent is my preferred method... Each to their own...  Pete

I agree use it or lose it. On everything.
I always everyday, make sure I get the 2nd Turbo to kick in. 2018 SE SDV8 4.4 Byron Blue

Agreed. Open the taps for that second turbo to clear its guts...I do it regularly once engine up to temp. Gone to a good home: 2011 4.4 TDV8 Vogue SE Buckingham Blue with Ivory and clear glass = "Rory"

Can anyone explain by what physical process a mechanical system will last longer by subjecting it to more stress?
Should I drive faster, accelerate harder or for more miles to increase the lifespan of the engine, suspension, brakes etc……. 2012 TDV8 Vogue (L322)

I try and get my second turbo spinning once per journey to stop the oil building up in whatever pipe it sits in…. I don’t have the turbo drain mod….. it smoked a bit when I first got it, and that has stopped the issue.
