Getting to a dealer from Watford usually means a recovery movement, so the sequence matters: drain and flush first, establish whether the system has latched, and only then decide whether a dealer visit is unavoidable.

The geography affects arrival time and disposal, not the outcome; that is decided by the contamination direction and whether the engine was run.
