Fixing the DPF differential pressure sensor error

My 2010 Audi threw a fit and started complaining about having some issues with error codes about the G450 sensor, #P0473 Exhaust pressure sensor 1 and #P2453 Dieser particle filter differential pressure sensor. After the change I did diesel particulate filter cleaning by enabling VCDS DPF regeneration.

Apparently the DPF pressure sensor had failed so I regenerated the particle filter and changed the bad sensor. DPF sensor replacement.

For this fix, a proper diagnostic cable is needed. I used Ross-Tech's VAG-COM HEX+CAN-USB cable and software called #VCDS. Code might also be P2002, part in Germanese is called differenzdrucksensor.
