I am a VDO authorised service agent, meaning all my products come from VDO Australia, and have a 2 year local Australian warranty. Further more if you have any problems whatsoever you can speak directly with VDO trained staff who have access to the entire VDO technical library and can simply call a VDO engineer if they need to.
