Hello,

I have a Bluetooth ODBII device that I have used to diagnose 2 warning lights on the dash. Output below.
Googling the codes, it looks like I need to replace the DPF Sensor in my car which I have located here:


Car is VW 1.6TDi Golf

Question:
Q1) Do I need to disconnect the car battery to fit this?
Some videos lead me to believe it's a case of unscrewing it from the brackets, unplug from 2 hoses and refit the new one with the opposite process.
Q2) With my ODB scanner, I just clear codes, turn the car on and that's it fitted?

=========1===========


P2454
Raw code: 2454
ECU: Engine control unit
Status: Confirmed
OBDII: Diesel particulate filter (DPF) pressure sensor A - circuit low

=========2===========

Status: Pending
OBDII: Diesel particulate filter (DPF) pressure sensor A - circuit high

=========3===========


P2453
Raw code: 2453

=========4===========

Thank you

No need to disconnect the battery, just change as you suggest and then clear the codes and see what happens.
Worth checking the hoses to it from the dpf are not split somewhere and in good condition.

No need to take the battery off, just remove the clips/fittings then take off the pipes

Good luck, last one I did didn't want to release the pipes but got there after some swearing and cuts to fingers wink
