2000 Passat Secondary air pump

Thanks,

The service Mgr is telling me that I must be driving though high water
(which I haven't) which ruins
the low mounted pump. Is that explanation plausable?

only if you drive through 12" deep water. But then again the pump is sealed
well. I stand by my first idea, if none of the plastic lines are cracked and
seal well, especially at the pump... then it's the combi valve.

Thanks again,

They claim that internal "VW Tech" says your analysis is incorrect and l
insist that somehow
I have flooded out 4 pumps" (without drowning the entire engine/car?) by
driving in high water
and they are not paying.
Of course they are full of BS as your analysis is confirmed here (and I
havent been driving in high water):

"In the case of a failed secondary air pump, the actual cause is frequently
not found in
the pump itself but instead in a sticking non-return valve between secondary
air pump
& exhaust manifold for example. For this reason in the case of a failure all
components
togeather must be checked"

..
They will be happy to repair for another $700.00! Shouldn't this covered by
the emmisions warrantee?

Should I bend over on this? (Clear Lake VW in Houston)
