    Egr valve problems
    Euro 6 102
    Had an oil sensor go on the van the other week which through up a start stop error on the mfd called roadside assist and thay sent the AA out to me, as the AA can read the codes numbers but cant tell what they are related too, iwas then told to book the van in Bradford van centre
    Rang bradford van centre the next day and they booked the van in, had to wait a week for them to have a look at it so i rang vw assist and requested a vw assist not the AA
    Assist came out to the van and cleared codes and replaced oil sensor egr code still there
    the van went into Bradford commercial on monday egr replaced and codes cleared

    The date that was recorded was nearly a year ago, are you sure it cleared? Go into the module itself with VCDS and clear the fault codes again.

    EGR is a taboo acronym to me; we had ours replaced three times in our T5.1 Cali...

    Van centres keeping it for a day or so to run some test on it
    no one can understand why the error codes are not showing up on the MFD butt show up on the code reader
    Not feeling much love for this van at the moment
    Anyway they given me a 140 to play with, totally different van to drive

    Fingers crossed for you! If anything else comes up, make sure it doesn't need a software update - it took our dealer 11 WEEKS to realise our T5.1 180 needed one to go with the three EGR valve replacements.

    Is the 102 five speed? I think the 6th gear of the 150 and 204 helps a lot. A bit hard to remap in a sixth gear though.

    Aha, the value of a VCDS shown to enable a visit to the dealer and workshop by an informed and intelligent customer who has, therefore, a dealer bluff potential of zero. I hope that the fault is cured once and for all, but I expect regular VCDS checks will now be conducted. Fingers crossed and good fortune.

    @Shaw many thanks for the update :thumbsup:, please let us know how you get on with the software update. Its worth noting the difference on mpg, as some are having difficulties matching others mpg, and although I know everyone's driving styles are different:whistle:, the EGR/software is worth questioning with the dealer to make sure the vehicle is up to date.:thumbsdown::thumbsup:

    @Caravellet6 Good Luck and I hope you get it sorted quickly and that the mpg is improved as a result.
