    8.1S Cylinders Loading with Fuel

    ZF Hurth Transmission - Filter

    Thanks... I just heard back from ZF Hurth and they are telling me I need to change it, but I'm thinking they are just trying to make a sale and it's the 'safe' answer to give. Have you personally cleaned your filters and re-used them?
