Will this have the b16/14 sensor? It's constantly reading as zero C on my icarsoft scanner and I cant see it where it is supposed to be fitted.

It comes up as exhaust temp sensor.
Sometimes there are 2 temp sensors in the exhaust system, one at the forward cat, another at the DPF (if you have one).

I have one upstream of the dpf which I just knackered, and one upstream of the turbo.

Unless a wiring fault with the B16/14 it looks like you need 2 new exhaust temp sensors.

V often the rust locks 'em in, more so on the DPF, and the thread becomes knackered on removal.
Lots of Plusgas might help, and run exhaust up to (an unknown) temperature.

While differential pressure initiates a regen, I would expect the knackered temp sensors would inhibit that.

So it's been going into regen every fifteen minutes and it's been driving me nuts so I've resorted to sticking all sorts into the dpf to clean it, which has knackered the sensor showing 1200. The b16 one has never shown anything buy zero.

time to replace the sensors. Clean the area where they screw in. Plus gas every day for a week. Magical stuff it is

Plus gas?

Ignore googled it.

Do I definitly have the b16 sensor?
