If you are getting EVAP check engine light codes P2407, P2405, P0496 etc. you probably have a bad purge valve. My 2016 DS was getting roughly 1 or 2 check engine lights a month with same the same codes for years.

P2405: Evaporative Emission System Leak Detection Pump Sense Circuit Low

P2407: Evaporative Emission System Leak Detection Pump Sense Circuit Intermittent/Erratic

P0496: Evaporative Emission System High Purge Flow

You need to buy a replacement Bosh Purge Valve. Got mine for $75 on Amazon.

The EVAP assembly is located in the rear driver side wheel-well.

1. Lift car and remove rear wheel opposite to fuel cap.
2. Remove the wheel-well cover.
   • Need Philips head screwdriver
   • #8/#10 socket wrench and extensions
   • WD-40 rust remover
3. Disconnect electrical wire.
4. Disconnect hoses.
5. The whole EVAP assembly needs to come down.
   • remove the 2 screws holding assembly
   • Disconnect hoses
   • Remove cable connector
6. The canister needs to be removed from assembly bracket.
   • Remove the 2 screws
   • Wiggle the canister up from the assembly to separate
   • Disconnect hose
7. Remove the purge valve next.
   • Need T20 star screwdriver
   • remove the 3 screws
   • Wiggle purge valve to separate filter
   • Disconnect power cable
8. Install new purge valve.
   • Wiggle filter and purge valve together
   • Connect power cable
   • put screws back
9. Reinstall the canister.
10. Reinstall assembly.
    • connect hoses
    • connect power cable
11. Reinstall wheel-well cover and wheel.
    • You should be done at this moment
12. Test run the car.
    • No check engine light was tripped
    • Have an OBDII scanner just in case

Overall the whole process took 2-1/2 hours on my first try. I can probably get it under 2 hours if I had to do it again.
Knock on wood, hopefully no more check engine light.

Thanks, it had to be done. So little info out there on this subject.

Update: it’s been a month and no faults to report. The fix seems to be working.
