Having issues with your VW Tiguan's fuel door not locking properly? This fuel tank door lock motor actuator might be exactly what you need to fix that problem. This is the control unit that operates your gas cap door lock - you know, that thing that should click securely when you lock your car but sometimes stops working. The part number you're looking at is 5N0 810 773 F, and it replaces several older versions including 5N0810773, 5N0810773B, 5N0810773D, 5N0810773E, and 5ND810773A (they all do the same job, this is just the updated version). It's basically a direct swap for your old, broken unit. Installation is pretty straightforward if you're handy with car repairs - just disconnect the old one and plug this new one in. We do want to mention that the price doesn't include any customs taxes or fees since we ship internationally - different countries have different rules about import taxes, so you might want to check what your country charges before ordering. But the good news is this part comes with a full 1-year warranty, so if anything goes wrong (which it shouldn't), you're covered. Just make sure this part number matches what your VW Tiguan needs - if you're not 100% sure, feel free to message us and we'll help you confirm. This should have your fuel door locking securely again in no time!
