    DV Servicing??

    Just interested if I should service/ replace my DV. I've had a hyperboost on the car for nearly a year without any problems. As I'm not technically minded I didn't know whether they are a consumable. Can they be serviced? It looks litke a sealed unit.

    Cheers.

    Maintenance of Diverter Valve.

    1. Obtain service kit from AMD.
    Contains:
    Revised Spring. (stronger 2.5mm wire instead of 2.2mm)
    Sachet of grease
    6 new cap head (Allen key) screws
    3 O-rings :
    Lid 46mm x 1mm
    Body 43mm x 2mm
    Piston 40mm x 2mm




    2. Remove DV from vehicle.




    3. Remove 6 screws and dismantle. Lid will try and separate when you undo screws as the spring is beneath it.



    4. Once dismantled it should look like this:




    5. Clean Out DV. Removing old O-rings x 3.

    1 where lid seals,
    1 on piston
    1 inside the bore of the DV body.







    6. Here is the old spring compared to the new one. Same height dimensions and coils, just stronger wire, for more spring force:




    7. Replace O rings with new, lubricate bore, O -rings and piston with supplied grease and reassemble with new spring:

    Cheers Jester but I'm sure mine is sealed so cannot be serviced. I think a new one is in order just to be on safe side. Its done nearly 13,000 miles.
