The shop was hired after pitching against agencies including Mother London and Adam & Eve.
UK shops Mother and Adam & Eve were thought to have been told last week that they had been knocked out of the review process last week.
Taxi, which has an office in Amsterdam and was acquired by WPP's Y&R network last November, now sits on the VW roster alongside the brand's long-standing incumbent DDB UK.
The review, which kicked off in February, was led by Agency Assessments and run out of Germany.
Taxi Amsterdam refused to comment.
