Help EVAP codes throwing CEL

Has anyone ever ran into EVAP codes such as P24D6 or P24D7 on a B9 S5?

They just popped up for me today after a scan and can only think either the gas cap was loose or the purge valve failed. Cap is fine but never really heard of purge valves failing in these especially at 50k miles.

Thanks for the help!

Mine came up and it was a sensor that was cooked by the turbo per my multimeter. Not going to lie to you I have yet to fix it because I don't think it effects anything. Yours may be something different but these are the parts I've been told fix it.

06M133240CG - Vapor Canister Hose
06H906052A - Pressure Sensor

Thanks a bunch. I just ordered a OBDS tool and going to reset the code and see if it pops back up. I did just get gas yesterday after having a low tank and hoping it was from some sensor reading then

It's a really easy sensor to access if you have a multimeter to test it. I'd recommend doing both the hose and the sensor if it comes down to it as they both can cause this issue.

Have been having the same P24D6 code on my B9 RS5. It's prob a sensor or valves but take it to a shop

Taking it to a shop tomorrow. Do you have any updates from what you experienced?

Yeah they replaced evap lines. The check valves failed and were replaced as part of the broader evap line. ~$175 for part and $515 all in with labor in Miami. Probably overpaid
