It would only affect the warranty on the dump valve anyway, nothing else.
Onus would be on the dealer to prove your new dump valve was responsible if something went wrong, but your just uprating a part.
Besides the Bosch dv is one of 4 or 5 items that is a regular weak point on the 1.8T engine, upgrading it is common sense.
My dealer never ever questioned my Forge 007 or the Bailey DV I had before it
