what is the radio code to unlock tiguan

Each car has a different code. Check your owner's manual. There may be a card with your specific code. If not call the dealer with your VIN number Alex

Don't know about the VW's,but the newer Honda's put the radio code on a label/sticker inside the glove box on the left or right side and maybe on a card as stated by Alex.NO two vehicles have the same radio code,that would make it to easy for radio thief's!
