Cayenne Diesel DPF fault codes

[s1962a]

Need some help please - been trying to fix DPF issues on our 2012 Cayenne Diesel, with the following codes thrown up

P0544 - Exhaust Gas Temperature Sensor Circuit Bank 1 Sensor 1
P2463 - Particulate Filter Restriction - Soot Accumulation Bank 1

Car is in limp mode with both engine and glow plugs light flashing

So far I have been able to put some cleaning solution directly in the DPF (through the DPF EGT sensor hole), and it seems to have cleared something, but it's probably still blocked. The car won't do a manual regeneration and I can't seem to kick one off from the diagnostic tool I have either (ICarsoft POR 2.0)

What i'm concerned about is that I can't seem to clear the P0544 code at all. The other one goes away and then comes back after I drive and restart the car, but i'm thinking one of the EGT sensors is failing. If so, which one could it be? Any other tips on fixing this myself would be appreciated.

Cheers

Bank 1 Sensor 1, is the first temperature sensor you come to as they are numbered from the head, with 1 being closest to the head. To further check it's the right one if you disconnect the sensor you should see a fault code for sensor to earth, can't remember the number, failing that look in live data and select to see bank 1 sensor 1 and bank 1 sensor 2, that way when you disconnect the plug you should see the value change. The plugs are usually colour coded to help avoid muddling them up.

HI you cannot do a manual regen with any fault codes,u need to do a regen VIA diagnostic kit,it takes about 30 mins.
The dpf temp sensors are common issue.
