I've no chance of getting back to "normal" regens now, but I'd be having a long chat with VW as to how exactly you adapt the new sensor, for I wasn't able to get it to work as the old one had, which is rather odd, but like you the stock DPF days were numbered so I didn't dwell on it.

Hope to have options on the DPF soon, just need to prove it will work....
Thanks, I might give this forced regen a try. I'll let you know how I go.

you havent tried going for a long highway drive?
I drive my GT for 40minutes each way to work on a highway. I have never really noticed a DPF regen, maybe once or twice. But I'm pretty sure it gets hot enough for long enough during my normal usage to not need them much. The soot levels have always looked fine when I've checked using VCDS. So I wouldn't except my DPF is actually clogged.

The difference between the "implausible" and "signal to high" messages seems to be that the implausible message is when the signal is intermittently shorted to plus an the "signal to high" is when its always shorted to plus (have a look at the logs in the links I posted).
