I had been called out because someone told me all the DPF options in his Snap-On Solus Ultra for this vehicle vanished after Snap-On updated his Solus.
In the end it appears nothing is actually wrong with the actual DPF, may be a intermittent fault with pressure sensor (or even wiring/ECU). Car previously had code for pressure sensor short circuit, but this did not reoccur while I was with it, even after test drive.
However with ODIS S 2.2.6, I only found option to teach in DPF parameters after DPF/Pressure Sensor/ECU replacement, no options for Standing/Driving Regen.
My initial suspicion is that the engine may be "tuned" but I could find all live data parameters with sensible values, I found pressing accelerator made DPF pressure value rise sensibly (I think was approx. 30mbar at 2000rpm off memory), and I could see car had used approx. 70 litres of fuel since last regen, so I was happy the car has still got DPF, DPF not blocked, and it is still trying to regen when needed.
However just for interest, I plugged an old VCDS clone (V12.12.0) and I found option for Service Regen while Driving.
Car has not been into Audi for any recall about emissions as far as we know.
So has anyone got any idea why Snap-On with 2016 update and ODIS S from early this year/late last year does not offer regen function, but 2-3 year old VCDS clone has got the option?
