Afternoon, I am about to change my DPF Pressure sensor in the hope that it fixed the P2455 error on my car. I have seen some anecdotal posts on this forum saying i need to reset the new sensor with VCDS or something along those lines, can someone confirm this is the case or if simply fitting the new sensor and clearing the old faults will be enough. Thanks

Pretty sure it will need adapting.

 

There are some details here for the 2.0l TDi so I'd expect the 1.6l to be similar: http://wiki.ross-tech.com/wiki/index.php/2.0L_CR_TDI#Exhaust_Gas_Differential_Pressure_Sensor_.28G450.29_Adaptation

From what I have read it needs adapting before you should drive the car

If thats the case ill have to find a VCDS owner on here and change it there, should be too difficult, do i fit the sensor and then without turning the car over follow thes steps posted in the link above?

Thank you for the details, very useful.

As far as I know, it's case of running the above steps immediately after fitting without starting the car. I'm sure someone will correct me if I'm wrong as it's not something I've done personally.

 

If you don't find anyone closer, I'm probably just over an hour away so I could bring VCDS over after work one night if it helps.

Thanks, i used the owners map to message someone more local but thank you for the kind offer. I'll give it a go, worst case is i bust a £15 sensor so no harm in trying.

I'd be more worried about damaging the DPF

 

Hopefully you'll be able to fit it without needing to drive before adapting.

I changed mine, 1.6tdi, only 5 minute job.

Cleared errors with vagcom/vcds

If car starts doing a regeneration you will be fine
