DS7 Crossback: Fixing P2453 Fault Code – Exhaust Differential Pressure Sensor Diagnosis & Replacement

[DIY Enthusiast]

Recently ran into the P2453 Exhaust Differential Pressure Sensor error on my DS 7 Crossback.
I made a quick video guide on diagnosing and replacing the exhaust differential pressure sensor to solve the P2453 check engine light

Thanks for posting that but a small point, I found it much more watchable with the sound muted!! I'd prefer some comments on what you are doing etc.

A few days ago I helped a neighbour replace one of these on his VW camper van with fault code P2452 (diesel particulate filter pressure sensor circuit). There was a bit less space to work in but the hoses were a pig to remove and needed to be twisted a bit with pliers after the clips were moved down. A bit of washing up liquid on the new part helped the hoses go back on. We did not have anything to initialise the new part other than to delete the fault code so are hoping using the van a few times will work and also that it is not a wiring fault as it looked ok.
