When I was researching these fault codes it said that it was necessary to remove the alternator to gain access to the change over valve. When I was digging into the engine it seemed easier to remove the intake manifold. Is this true, or is there a reason I should not do this? Thanks in advance for your help. Ed 98 Boxster w/tip

I think the alternator is easy to remove but I would check the vacuum hose/piping to the valve and vacuum tank first as I have found that to be the cause more times then the solenoid valve.

I've done that already and have gone through the checklist on the pump and all seem OK. It is time to bloody my fat hands and go inside. Thanks for the info. Ed

i'm sure you are aware, but be as careful as your "fat hands" can be in working over there. Those little black plastic hoses are brittle. Especially the hoses from the waterpump! ask me how i know:( lol
