i did have x2 other ones but they were mass air flow which i have done also intake air temp sensor which i wasn't bothered about as its only the onboard temp on the cluster right?

other than that these are the codes left on my list to sort out.

its the C1022 code im bothered about. i know there is a reluctor ring around the hubs? is that right which do rust up and cause problems?

im running out of ideas but this C code is the one i want to eliminate most. i tried resetting the ecu by unplugging the battery but no joy there.
