Hey Mike,

Been good mate. Due to COVID the car doesn't get any long runs at all , especially now that i'm no longer on the road for house calls etc. Every wednesday night after i drop one of the kids off at guides, I'll go for a 25 mile forced regen run so it doesn't get near the 1st trigger. This has been a fantastic addition to the toolbox, and again has saves quite a sum of money in the long run.

Cheers

steve

Great news, but don’t force it too often or you will risk getting oil dilution problems and need to be doing extra oil changes..

Just changed my oil because it said service needed. My IID tool said oil dilution was 3. So is the mileage involved as well?

The WM gives this explanation , all very complicated, but seems to involve, time since last service, amount of fuel used, mileage, ??

Thanks Mike. I'll count 3 as being good then, probably. Confused

I'm just about to try this forced regen as I've had my first ever yellow warning (which has actually gone off again now - I actually think the garage did something as it came on when it was being delivered home after a service).

Does the forced regen process complete itself, or do you have to quit when you think it's done enough? 2010 4.4 TDV8 Vogue SE

Sorry, but I can’t give you a 100% answer because I have had different experiences , but what I usually do is watch as the soot gramma fall to single figures then stop at the next convenient place, lay-by etc and stop it by pressing the Quit word and removing the iid.
I usually then complete my journey and check the final figure in live values.

Cheers. I'm not sure when I'll get a chance to do it but will do what you suggest when I do. 2010 4.4 TDV8 Vogue SE

Ok, all good info.

I recommend only doing a forced regen as an absolute last resort. It blows through the safety nets and can be quite brutal to the matrix on the DPF and/or the cat. Relying on it regularly or as a standard operating procedure is a bad idea in my opinion. Personally I would only run it if stuck on a red or to get home. On a yellow try and get the car to clear itself naturally.

If you're getting warning lights it generally suggests another issue like induction system if you're not mis-purposing the car for something like city driving.

The oil dilution figure on the IIDTool is inferred and not measured. It is calculated by the number of regens since the last service. It is not a very reliable indicator.

Just an observation that I will add……..
The number of successful Regeneration count in live values does not change after a forced regen has been completed, so this may well affect the “oil dilution “ calculations, but the overall contamination must be affected.

Absolutely agree. On other cars where I've had this facility with a diagnostic device it's come with big warnings. Should only be used in emergencies and if a long >50mph run doesn't clear a yellow fault you have other issues that need fixing ASAP 2012 TDV8 Vogue (L322)

Completely agree - the Successful Regen field does not populate consistently after regens - natural or forced and under the same conditions it will sometimes tick up sometimes not.

This is definitely a controbutory factor to the well known unreliability of the Oil Dilution...

FYI Demanded Regens is spot on and is the best way of seeing if the car is requesting a regen. On mine it kicks in like clockwork at 19.7grams of soot. Also I have replaced every sensor including the pressure differential which calculates the DPF soot fill and it still kicks in at 19.7grams. 2012 L322 4.4 TDV8 AB low mileage - a peach

I haven’t needed to use the iid forced regen facility for a while, but today I decided to give it a good clean out .
Here are the screenshots.

I know from past experience that the display doesn’t show readings below 1g correctly, and that 6g is actually 0.6g as confirmed by the live value reading of 0.558g at completion.

I love this forum for educating me on the DPF in my car and helping me avoid the dreaded amber or red warnings.

Spent a good few hours earlier in the year trawling thru all the threads and getting the facts straight in my head, it's a goldmine of cold hard data and user experience/knowledge.

I rarely get long runs nowadays so keep an eye on this using my Gap tool and have successfully called in a few forced regens

Any word if they're going to include it in the proper build and not in beta only, wonder what is preventing them from releasing it fully into the live code ?
