DPF Red Warning ! Please help

Got the DPF full visit dealer message today Confused a couple of days ago i got a restricted performance message and have since noticed a suspected air leak on one of the 4 short rubber hoses that join onto the donut so suspect this is the cause of that. I have had a DPF full amber warning before on a few occasions and its always cleared after a short drive and its done a regen but this time its just gave me a red warning. I used a Snap On Solus and got these codes, P2463, P040D, B1D24 and B102E. Will it be because of the heater plug code that it has not done a regen ? i tried to do a force regen and it did a soot level check and said it was below the level for regen ! confused a lot Confused Any help would be good from all you fellow Land rover buffs Thumbs Up Thanks Neil.
Can't upload any pics but these are the codes and descriptions:
P2463 Diesel Particulate Filter Restriction-Soot Accumulation - Bank1
P040D Exhaust Gas Recirculation Temperature Sensor A - Circuit High
B102E Air Quality Sensor
B1D24 Glow Plug Circuit

The codes with B are battery related so can be ignored... The P040D code relates to an exhaust temperature probe... If this reads low temperature then the engine ecu can up the fuel rate (like a choke) and this fills the DPF with unburnt fuel... Does your car smell like a 1970's ice cream van?

Thankfully many problems on the 4.4 TDV8 tend to be the same ones so, it makes diagnosing quite easy.

The usual culprits (in order of easiness and least expense):
1. MAP sensor. Usually gunks up every few thousand miles, which can result in false readings to the ECU, resulting in over-fuelling or false demands for exhaust gas recycling. It's 1x T20 screw and can be cleaned with electrical contact cleaner. Also clean out the hole with an ear bud or some paper towel (job takes about 2 minutes)
2. Silicone charged air and inlet manifold hoses (as already discussed above). Sometimes holes can be so small or fine cuts, the only way to see them is by taking off the hoses, having a good look and squeeze with a torch. Also check the lower hoses. The left side turbo lower hoses can quite easily be inspected by undoing the glowplug bolt (like you would when doing a service) and removing the airbox. (Job takes about 30 minutes to check and replace hoses)
3. The plastic union which joins the throttle body from the left charged air hose with the metal clip. The green double lipped rubber seal begins to collapse over time and causes intake leaks. Characteristics are soot/oil deposits around this area of the engine bay and on the paddles inside the throttle body. Permanent fix is a new hose which is £175. You can try a temporary fix with a high temperature sealant, putty or gas specification PTFE tape. (5 minutes to replace this part or 30 minutes fannying around trying a temporary solution)
4. The exhaust gas temperature sensor. It's not expensive itself but does involve removing a load of bits to get to it

Very rarely is the DPF error message the DPF, its usually a result of one of the four above. 2015 Range Rover Autobiography 4.4 SDV8
