I suspect that it might be worth the 50% extra cost to purchase the Laser Tool's 6-point version of the tool rather than the cheaper 12-point in case the sensor is somewhat seized in the manifold.

Yes Graeme I've ordered the tool.

I'll take pics. A bit worried it'll be seized in there....

Hopefully be able to do it next weekend.

Which one is the laser tool?

I can only find one 13mm sensor tool - which is the JLR one.

EDIT: ok got it there are 12 and 6 point versions. Was going to get the genuine one, can't find a pic of that....

It's not crystal clear but the JLR looks 12 pointed in the WM:

Yes, too many points to be a 6-point.

ok great shout I think I'll go for the 6-point

As the sensor has been revised, hopefully it won't ever need replacing again so you could sell the tool especially being a 6-point that is unlikely to get damaged. I suspect that I'll be replacing mine's sensor and the tool would be coming from the UK, possibly with a sensor in the same package to save on postage.

Greg,
Given that your soot level came down to 4.8 after a decent run out of town traffic shows that your car is functioning correctly despite the PO40etc alarm, exactly the same as mine and Nino’s, which have both been fine despite the fault being present for many thousands of miles.
Sometimes it is best to leave things alone.
“If it’s not broke don’t fix it” mentality 🤔🤔

I'd like to know if mine's single EGT sensor is used as a safeguard against excessive manifold temperatures if another sensor reads incorrectly yet is still within acceptable bounds. I intend eventually to get EGR mapped out so pre and post cooler temps purely for EGR control wont be required. In the meantime though, a non-operational sensor could possibly lead to more or less carbon build-up in the air intake. If the EGR inlet temp's default value of 100 deg is taken as gospel then the EGR cooler bypass valve will always be open, but IIDtool live value logging should reveal the valve's status.

Hi Mike, well yes I know - the regen process is working well both Active and Passive, proven in the past week.

But my DPF does fill silly-quick. Almost in front of my eyes. I sat in traffic and watched it go up. Yes I'm doing 20mph most of the time, but since I had it removed and cleaned then reading zero, it filled up to 23g within in think just over a week of short journeys.

I don't believe that's normal. Plus I have a diesel smell on cold idle. That's one of the symptoms Craig mentions.

Craig said;

Quote:

The first code is for a sensor in the NS exhaust manifold, this tells the ECU its running lean or rich this then increases or decreases the fuel trim... If it fails in one position then it will over fuel the car and it makes the exhaust STINK like a 1970s ice cream van! This will fill the DPF prematurely and cause restricted performance issues too...

Patrick @ Gap advised that their tool has the complete live value list implemented by LR.

I note that the wiring schematic incorrectly labels the 2 EGR temperature sensors as a 2nd set of pre and post catalytic converter EGT sensors, with the descriptions corrected in a correction document. With live values available for other EGR components and operation, it appears that the EGR temperature sensors were missed in more than one respect.

Found this in the workshop manual:

BTW I'd be interested in knowing what 2F means.
Anyone know?
. Cheers, Greg

The wiring for the EGR inlet temperature sensor is on the engine as is the wiring for the EGR outlet temperature sensor, so another indication that the sensor is the one in the manifold.
