My Golf 7 has a misfuelling protection in the filler neck, so I could not top up with a "normal" pouring diesel out of my jerry cans. About the adventurous explanations of VW, the breakdown service and a testing center of automobile clubs I do not want to report to avoid being accused of defamation prefer. My necessary research revealed that there are already about my Hünersdorff canister a spout that opens the lock located in the filler neck as misfuelling protection. After I had the Diesel spouts in hands, I could convince myself that the misfuelling protection is not an obstacle, and I can pour out my jerry diesel in the Golf 7. Unfortunately, there is no 3 L canisters (available from 5 L) in the professional version, in which the filler pipe can be clamped in a U-shaped depression of the canister and allow the storage problem is solved very elegantly. My verdict is clear: A very good in terms of function and especially absolutely necessary accessory to refuel a secured with misfuelling protection diesel vehicle from a jerry can.
