Soot load is calculated from differential pressure across the DPF and estimated ash load. It’s all estimated really and any excessive pressure differential should be properly investigated and not just be assumed to be soot load that needs a forced regen. It can be something else like a partially melted pre cat or very excessive ash load. 2012 TDV8 Vogue (L322)

Hi mate it was a split in one of the intake pipes that has caused the build up of soot

Just an update, have given up on the icarsoft and bought the GAP IID. Forced regenerated the car and then cleared the codes and all back to normal with the red dpf full warning gone. Took the soot content from 33.4g to 0.6g. Wish I'd just bought the IID tool at the start instead of wasting money on the icarsoft.

Ditto. I bought an icarsoft being a tight northerner and then realised its compared to the IID. IID now in glovebox permanently

Can anyone list the things which will stop IID from doing a forced regen please?

Im at 31.4g due to an air leak which is now fixed but the forced regen isn't bringing it down.

More than 1/4 tank fuel, only error is P2463-00 dpf pressure sensor B circuit range/performance but I assume this won't clear until the pressure differential is at an acceptable rate?

Thanks

Which versions of the iCarSoft are we talking about above? 1, 2, or 3?
I think it might make a difference…..  “If it ain’t broke, don’t fix it” -where’s the fun in that?

That DTC will prevent a regen (correlation error) not be set due to one being required. Check the differential pressure with ign. on, engine off - should be pretty close to 0kpa, anything else can point to blocked pipes, condensate in the sensor or a faulty sensor, all of which are 'Tom Jones' problems.

Hi, just checked and the "Particulate filter differential pressure - measured" is reading N/A whether the engine is running, or just ignition on. Am I looking at the correct live value?

Cheers

i carsoft can clear red dpf and force regen as i pointed out 6 month before gap decided to allow people to do this it can be done just seems lile there is some issue
the iid is all singing and dancing but also a chunk of money in the fact that mine sits in glove box just waiting to be used

hi you must be driving to force regen, the carsoft will tell you what you should be doing to get it going been a long time since needed to do it
but i seem to recall speed only needs to be above about 25mph which is easily done as opposed to 50mph

Nice one. That's really helpful. Will limp it onto the motorway later and give it a go. Thanks again.

Good luck - interested to know how you get on - please update us on here?
