Review on 🔒 Fuel Gas Cap Replacement Seal for Volkswagen & Audi VW MK4 MK5 MK6 B5 B6 B7 B8 Petrol Gasket - RKX by Maurice Harvey

Thicker than OEM but just what you need. As soon as I came across the code, I checked it with a code reader and googled it. The three most likely causes were a leaking gas cap. I checked and sure enough it was cracked and bone dry. I replaced it with this one for a while instead of buying a new one. I haven't seen the code since then. Good value for money!
