    Hi,

    Looks like the EGT sensor from what google told me, but the 17865 & 17538 errors I cant find anything really about them. Is it mose likley just the sensor or is something else going on. Also would it be ok to drive for a few day until i order that part, Its about 20 mins to and from work, so not much?

    Thanks in advance.

    Rob

    17865 is the EGT on the other bank

    17538 is a "system too lean" fault code, which suggests an airleak, faulty lambda, or faulty MAF.

    Try resetting the codes and go for a drive and see if they come back.

    Driving to work shouldnt be a problem, so long as you dont go booting it.
