Review on 🔒 Enhanced Fuel Tank Cap by URO Parts - 4B0201550H by Brian Douglas

Perfect! Now there are two reasons you might need this: a fuel cap warning light and an engine light for zero vacuum in the evaporator system. Newer cars (maybe 03 and newer) have a magnetic pickup right where you fill where the cap is. You need a different fuel cap for this warning light. Now if you have a CHECK ENGINE light and code for small/large evaporator leaks then this cap will fix the problem if your old cap is defective and the problem is not with another hose or component in the EVAP system. This cap passes the vaporizer system test on my 2000 B5 S4 and 2005 B6 S4, but my 2005 B6 S4 has a magnetic sensor on the filler neck and there is no magnet in this cap so the light does not work. a way.
