Hi guys!
This is my daughter’s car, and she’s getting rather frustrated by the restricted performance / limp-home mode.
I understand the DSC message is linked to the EGR valves, or so it seems, because they always appear in parallel, and seem to cause the restricted performance mode. Oh yeah, and often paired with DPF having too high pressure (being full).
I’m in good mind to get rid of the EGRs altogether but understand this being a 2009 MY, it will need some kind of re-mapping.
The messages I’m picking up with my ODB-II reader are:
P1 40A-21 EGR resirculation sensor C - circuit Low.
P1 40E-21 EGR position sensor min/max stop performance.
P0 45C-00 EGR B control circuit - Low.
P2 44E-00 DPF differential pressure too high (Bank 1)
Any wisdom here on this?
Kind regards,
Bard Thomas
