Need some help figuring this problem out. Here is a backstory

Got a CEL few days ago ran VCDS Code P2459 came up no other codes reset it. after a day it came back up again



Address 01: Engine Labels: 04L-907-309-V1.clb
Control Module Part Number: 04L 906 021 D HW: 04L 907 309
Component and/or Version: R4 2.0l TDI H23 9283
Software Coding: 011D0012032410081000
Work Shop Code: WSC 02415 444 00000
ASAM Dataset: EV_ECM20TDI01104L906021D 004017 (VW37)
ROD: EV_ECM20TDI01104L906021D_004.rod
VCID: 2600ED1C5914F6B658-8072
1 Fault Found:

8863 - Diesel Particulate Filter
P2459 00 [237] - Regeneration Frequency
MIL ON - Confirmed - Tested Since Memory Clear
Freeze Frame:
Fault Status: 00000001
Fault Priority: 2
Fault Frequency: 1
Mileage: 312336 km
Date: 2020.06.11
Time: 11:21:31

Engine speed: 1230.50 /min
Normed load value: 50.2 %
Vehicle speed: 56 km/h
Coolant temperature: 74 °C
Intake air temperature: 59 °C
Ambient air pressure: 990 mbar
Voltage terminal 30: 13.540 V
Unlearning counter according OBD: 40
Exhaust gas jet volume in particle filter: 106.5 m³/h
Particl.filt.: different.press.sensor 1 bank 1: adaptat. value: 85 hPa
Particle filter: soot mass measured: 21.62 g
Particle filter: soot mass calculated: 21.62 g
Particl.filt.: differential pressur.sensor 1 bank 1: dyn.offset: 0 hPa
Particle filt.inlet temp.sens.1 bank 1: raw value: 313.7 °C
Particle filter outlet temp.sens.1 bank 1: raw value: 244.3 °C


Here is what i found so far per recommendation.


EOBD II Error Code: P2459

Fault Location:
Diesel Particulate Filter (DPF) - Regeneration Frequency

Possible Cause:
Malfunction Indicator Lamp (MIL)(K83) active.

Heavy loads on engine (towing).
Short trips in cold weather.
Faulty Exhaust Pressure Sensors 1 & 2 (G450/G451).

Possible Solutions:
Change driving habits.
Inspect Exhaust Pressure Sensors (G450/G451) as per factory repair manual.
PM trap loading > dynamically rising threshold (simulated engine emissions).

Special Notes:
Depending on driving habits, soot can build up quickly in the Diesel Particulate Filter (DPF), thus requiring more frequent regenerations than normal.
With CBEA and CJAA engines, the factory documentation may show the wrong part location for the Exhaust Gas Pressure Sensor 1 (G450). This sensor is in a foil pouch just behind the oil cap.


So i don't tow anything & no short trips i normally drive around 100-130+ miles per day mostly highway

What i am looking for a way to test G450 or & G451 Sensor. I want to be sure before i start swapping parts

Car has around 194k miles so no more warranty
