I now have my own pucker VCDS running, and it was obvious the replacement diff pressure sensor was duff. I put another one in and it now seems to give plausible readings. However, I cannot seem to do the G450 adaptation because the ‘Coding II-11’ button is greyed out? Any ideas? (PS engine light is out for now but there is an offset on the switch with engine off (about 1000mV)

Thanks for the pm. Really useful if I have to ring it out after I check through VCDS again tomorrow!

I did, but will check again when I get VCDS going again on friday as I may have done it wrong…….

Thanks. Have just forked out £225 for the 3 VIN Ross-Tech cable now so should be able to plug it up on friday. Was a history of flaky switches around 2016 I believe….so I just swapped them both for abot £20 each

Thanks! Your help much appeciated……

Thanks. Sorry, I used a mate who has the vcds kit. Am considering spending £225 with Rosstech to get my own again…..my version was can-bus for the old Galaxy I had. I replaced both pressure switches so am thinking circuit error…..unlucky if its another duff switch? If i can get the right schematics I’ll ring it through to check. ….and odd that the forced regen worked just fine……?

Engine light on a few weeks ago, and error code indicated bank 1 pressure switch. I swapped both pressure switches, and then reset the adaptation in VCDS and forced a dpf regen which all worked fine and completed ok. Now there is error p2452 indicating a further error in the pressure switch circuits. Can anyone point me to an electrical schematic, or give any clue where this problem might be? 110kw, CUUB, 2016 Thanks!
