DPF sensor readings

Hi

Can anyone tell me the voltage reading on the dpf sensor when engine not running.
IIdtool says 7.3 volt but the only information I can find is that it should be 5 volts. fitted a ned sensor but readings are the same

I have a full dpf 27.5g and locked in limp mode

The only way to clear the limp mode red DPF is to do a Forced Regeneration .
It’s very easy, just follow iid screen instructions.

Mine reads 0.73x volt, engine not running.
Engine (cold) idle: 0.75x volt with a calculated soot concentration of 17.8 gram.
Engine at (warm) 1420 rpm: 0.79x volt, calculated soot now 18.6 gram.

I hope this helps. 2012 4.4TDV8

Tried to do the regen many times. Iidgaptool says "regenerating" but sootlevel just continue rising. I also tried with "fit new particulate filter"

and offcourse cleared DTC's

I guess some readings are not right, since its not regenerating

do you have half tank of diesel fuel ?

do you have a motorway type of road where you can drive at 60 or 70 km for 20 or 30 minutes without stopping ??

No need to rev the car, just cruise along at those speeds and the forced regen using GAP IID should work

Big mistake trying the fit new DPF , sorry but your iid now thinks your DPF is new with zero soot , 0g, so it won’t initiate a forced regen until it thinks its full, or at least above 20+g.

Not sure what you an do, unless you wait until it reads 20g higher than when you reset it

Drove motorway for about an hour.

I did a DPF clean my self, injecting cleaner in the pressure tube and followed the instructions incl. reset. I did wait until soot level was 20grams before starting the cleaning proces, and i dont know if it actually started the regenerating process, because you cant see the DPF temperatures in IIDtool when running the process. Would be nice though

I ended up taking the DPF for a specialist. He cleaned out the ash and cars running again
