Nothing need to be disconnected :)

[ivanko1504]

already worked that but if the pump is broken then it getting errors all time...in other case if pump work properly then dont need to disconnect just shutoff in swiftec or winols

Not really sure swiftec would work :rapture: even when pump is good.

said it... i already worked it..

Not all SW versions are the same, if one works with Swiftec it's not sure another one would also work
Anyway on VAG there's no need to disconnect anything with correct SCR Off solution
