New to forum hope this is the correct place for this, basically had engine management light on for about 2/3 months from when i bought the car, and then the DPF light came on, so bought VCDS to check this and found error code P246F which is the sensor 4 on Bank 1, i believe this is the sensor with orange coloured connector just after the DPF?

checked the values on advanced measurement (using VCDS) and sensor 4 is giving reading around 999.987 celsius which is clearly where the problem lies, and this is preventing a full regen of the DPF.
im not sure which sensor is number 4, and to confirm the problem i disconnected the orange connector from the car and i was expecting the temperature signal to disappear? but it kept giving the same value around 999.987 celsius, did an engine scan etc again and it is still giving only the original error, there is no mention of the sensor being missing?
also to check if there may be something wrong with the connector i removed the plug on sensors near the turbo and before the DPF, but once again the reading of temperature staid around 20 celsius when car is off, and this increases when car is running.
A bit baffled as to why I'm still getting reading when i disconnect all the sensors plug. could this be a bigger problem than what is showing on the VCDS, about sensor 4 bank1?
