DPF Differential Pressure Sensor (CJAA)
Bosch P/N: 0281006082
VW Part number: 076906051B
This is the part that reads the Differential pressure (D/P) across the diesel particulate filter (DPF) in your common rail TDI (see applicability below or contact us for compatibility). When it fails there may be a low power condition accompanied by a check engine light (CEL) and or flashing glow plug light. The DPF needs this signal to perform a regeneration, and no regen means the soot builds up until a check engine light appears along with one or both of the following diagnostic trouble codes:
009315 - Diesel Particle Filter
P2463 - 000 - Excessive Soot Accumulation - MIL ON
009299 - Diesel Particle Filter; Differential Pressure Sensor
P2453 - 001 - Implausible Signal
P2454 - DPF pressure sensor circuit low
8863 - Diesel Particulate Filter
P2459 00 [032] - Regeneration Frequency
The DPF warning light may also be lit along with the flashing glow plug lamp and check engine light.
Replacing this part, followed by a service regen, fixes the problem indicated by the DTC indicated above.
