Thank you thank you oh and in my excitement forgot to acknowledge getting yours done Craig. Well done
best bargain I've ever heard of. And I love a bargain.

I'm still glad I've done it myself, even if I could have got it for £200ish. I've 'enjoyed' the challenge it brings and I love tackling something new and difficult to prove to myself these things are possible.

I also wanted to get to the bottom of what seemed to be a bit of an unsolved mystery as far as this error code goes.

Does this mean I'm going to start reading up on how to do the Turbo Drain?????

. Cheers, Greg

Turbo Drain

I also just want to say that anyone who has been told this is a ghost code has just been fed that from LR or whoever through being misinformed. I'd say that my above error free status proves that.

Why do people think this? Well the beginning pages of this thread suggest that people are changing the wrong sensor. It's marked EGR sensor in the error code, it's one of two sensors for the EGR (A and B), but sensor A's location is nowhere near the EGR. And that's a fair trap to fall into because it is not clear in workshop manual that there are two EGR sensors. And A's location on the NS manifold is not documented in association with this code. Or within the EGR documentation. Note earlier pages on this thread discussing and doing detective work to confirm which sensor it really is. And where it is. The name of this thread itself gives away where this started.

If you change the sensor actually on your EGR (Sensor B we think), it's a waste of money and and the error will of course come back. It's pretty easy to surmise that many mechanics have changed Sensor B, not knowing there are two and when the fault returns it's leading them to issue bad advice to the next guy.

It's actually common to hear "they all do that" for this error code.

However, there was one expert who didn't say this. Cam Tech Craig. So best of all, I'm pleased to have independently confirmed in practice and what Craig has said all along.
Despite a strong notion out there towards the 'ghost code' theory. Huge respect and thanks for the pointers Craig.

Craig I also think you are right about it failing at either ends of it's scale. That's why some people can live with it and other have more obvious issues.

Turbo Drain

We all owe you a big vote of thanks for your pioneering work.
If you find that you you are definitely lasting longer before reaching the 17.5g soot level threshold then I am definitely going to get mine changed.

I will be home next week and getting to the bottom of why my DPF has suddenly started filling up so fast.

Thanks M@tt, Yes I've seen that place, actually I've been there to scope it out a while back.

A bit of an odd place, several small one man operations running out of some of the bays. I got a bit of welding done while I was there (not for the car) and still can't decide if I'd tackle a major job there.

What a glorious sight......well done Greg!

Mike

Thanks Mike!

I also found a lot of YouTube vids of Ford 6.7litre Powerstroke engines needing their EGT sensors changed. These are pick up truck heavy duty diesel V8s. Theirs are not on the manifold, and not necessarily connected to the EGR, but the sensors themselves look pretty similar.

Why is that interesting? Well these 6.7 litres Powerstroke's are related to our 4.4TDV8 engines.

How? Because they are made in the same Ford engine plant in Mexico.

Common sensors = dud supplier part me thinks. Parts bin issue.

It was a relief to see the new sensor looking quite different, along wth a new part number sometime along the way.

Craig's issue shows the old sensor is on plenty of 405's too.

I wonder how many they churned out before they started fitting the new version?

. Cheers, Greg

Had ours replaced whilst some work was being done they had the right tools and new what they were taking on. I managed to find the updated sensor on Ebay for £40 from someone who bought an never used it

I didn't have any running issues or DPF filling problems but I do about 300-500 miles a week in mine so its always given a good run.

But same feeling when the bf connected to code reader and there was no fault  2011 4.4 TDV8 Autobiography

Bit of an update from me; it's been a few weeks since changing the sensor. Done a few hundred miles.


DPF: It's a bit too early to tell. When I changed the sensor I was on 18g soot level so it was due a regen. Which I ended up doing when I forgot it was getting high and I got a yellow dash warning, which meant I'd climbed to 23.3g. Interestingly I drove out on my usual DPF Regen route and it climbed a bit on the way (no 50mph roads close to me) to 24-something grams soot. Once I'd hit 50mph the regen happened and I watched the EGT readings climb to 650 degrees as usual. This time though it 'burned' much longer, and I got a record burn range from 24grams soot down to under 2g. Never had that before. Is new sensor anything to do with this? No idea. I want to wait three weeks as that was my normal DPF regen time under my typical driving habits. If it lasts longer than 3 weeks then I'll have an improvement. This was the main reason I wanted to change the sensor. My gut is that it's filling up at the same speed as before.

Smoothness: Craig you mentioned yours was rough, then smooth after your sensor was changed. Mine seems the same, I'd say was smooth before, and it's smooth now.

Smell when cold: Possibly reduced, hard to tell.

Fuel economy: Bit to soon to say. I do short city driving and my usual tank range is 300 miles. I'll want to do a few tanks and report back.

Lastly, I did promise to write up a clean set of instructions and I'll do that in the next few days.

. Cheers, Greg

Greg,
I am sorry that the new sensor has not dramatically improved the soot build up level as we hoped.
18 up to 24 in not many miles is worrying.

We really could both do with a few more members logging their live values for a couple of weeks to see what average build up rates look like.

I can believe that the better Active regen you got is directly as a result of the new sensor, but if it is going to happen every 3 weeks, the oil dilution rate is a bit worrying.
Luckily I know we are both fans of regular oil and filter changes.

Let’s see what the next few weeks brings.

I topped up with 50 litres of diesel yesterday, then added another 50ml of Millers cleaner .

Yes Mike it would be good to see others' soot 'gain' rates.

For others reading:
Mike has had the turbo drain done whilst I haven't.
Mine has had the sensor done, Mike hasn't.

That's interesting because we are both having DPF soot gain issues i.e. DPF filling too fast.)
Although Mike, yours touch wood is settling a bit since you got back..

For me, Mike having issues yet HAS had Turbo Drain helps me, without knowing this I'd be rushing to get it done.
I guess vice versa for Mike using my sensor change experience.

I'd stress thought that I've only done a few hundred miles since changing the sensor.

Whilst perhaps a bit off topic for this thread, I am still thinking about other causes to my DPF fill rate. It may be purely down to my city driving and lack of motorway work.

But there may be something else.

I did read about throttle bodies playing up on a few posts...
Anyone with any thoughts on this?

Another area is additives:
- Mike your use of Millers is interesting too.
- I know Nino adds a bit of 2T oil to his tanks....
. Cheers, Greg
