EGT2 is in the middle of the DPF, between heat shields and EGT 1 is on the non heat shielded part of the exhaust near the flange of the DPF towards the engine front side . EGT3 has a part number of CG9A-12B591-AC.

I would be checking the EGT3 sensor operation..

Replaced the EGT3 sensor yesterday (Funnily enough they had one on the shelf at my local Ford).

I'm going to monitor over the next week or two to see how the regens go. Before replacement there was a 200'C difference between sensors during a burn. Hoping to see a smaller differential after replacement.

Bastard of a job to replace. After getting the car high enough to squeeze my (ample) frame underneath I found that the old sensor needed a different size spanner to the new one. I also needed to unbolt and bend out of the way the heat shield to access the probe.

It was #%$^ing tight, I ended up using a larger spanner over the smaller 13mm one to get enough leverage to get it started. I also cut the plug off the old sensor so I could use a ring spanner as I didn't think the flare spanner would take that much force

Hopefully this will stop my DTC issues. This week I will do nearly 1500km commuting to work so any issues should rear their head fairly quickly.
