Hi There, I have an issue i could really use some help on. 

 

I posted a couple of weeks ago (link below) about changing my DPF Pressure sensor due to a P2455 error. I was informed that the sensor needed adapting with VCDS and i was given a Ross-Tech link to the procedure. 

 

BIG nick helped me out with the adapting, i drove to his and fitted the new sensor and let him to get to work (the car was not started at any point). My car came up as UDS so we followed as per the instructions:

UDS Protocol (G450) procedure

Key ON, Engine OFF
[basic Settings]
Select Adaptation of diff. pressure sensor particulate filter
[Go!] to activate the Basic Setting.
After the result of Finished Correctly appears click [stop]

Select Resetting of learned values of difference pressure sensor
[Go!] to activate the Basic Setting.
After the result of Finished Correctly appears click [stop]
[Done, Go Back]

All was going well until the highlighted step. This option did not appear exactly as written like everything before. Instead it had the option "Adaptation of diff. pressure sensor particulate filter". We cleared this and another option sounding remotely similar and clicked done. The issue seemed fixed but a couple of days later i get a P2453 "DPF Differential Pressure Sensor Circuit Range/Performance". I can clear the fault but it reappear at start up sometimes, the car otherwise drives/act normally. 

 

I am thinking about buying another sensor, a more expensive one (original new sensor was £20 from ECP) as it sounds like it could be just a duff sensor but im worried it could also be the fact that VCDS didnt have the same options. Does anyone have insight into this?

EDIT: I have found another thread where some one had a similar issue

Seems people had the same VCDS issue, the exact wording is "Adaptation of diff. pressure sensor particulate filter" not "Resetting of learned values of difference pressure sensor"  as per the wiki.

I changed mine myself and the only thing I did was erasing all the errors.

No adaptation no nothing
