1.6 HDI DPF P1490 Fault, and some unusual live data

Post by shtu »

Recently, had the "Risk of filter clogging" warning, and a quick scan gave this detail,

So far so ordinary, although the car hasn't been used for short trips, 70mh for an hour solid is more normal. The dashboard warning went away after a few restarts.

Having a look at the live data, I'm intrigued by this, taken with the engine off, and not run for 3 days,

Which makes me think the pressure sensor is faulty. To me, there shouldn't be ANY "difference in pressure" with engine off, and as it's not-zero when off, it might be over-reading when running.

Here's idle,

And higher rpm while parked,

Any thoughts on those readings?
