P04567A recurring
On my 2022 GLC300 4Matic, around 15k miles on it.
I have had recurring P04567A back to back within a few days. Car seemed to run ok, but a little more vibrations than normal.
The first time I brought it in, the notes said
1. ZM AUTH RL OK .90 DIAGNOSIS 3:11PM 2/2/24 // verified concern, check engine light on. connected and disconnected battery charger and sds. performed short test. found code P04567A A very fine leak in the evaporative emission control system was detected. Leakage or a defective seal was detected. current and stored. follow guided test. performed fuel tank leak test. test not ok. continue follow guided test. check and test purge valve. remove under panel. upon testing found purge valve not holding vacuum. purge valve internal stuck open. purge valve must be replace. remove and replaced purge valve. reinstalled under panel. clear code. performed road test. ran short test again. no code return. all ok.
Two days later, check engine light showed after one refuel.
1. verified concern, check engine light on. connected and disconnected battery charger and sds. performed short test. found code P04567A a very fine leak in the evap system. leakage or a seal was detected. follow guided test. fuel tank leak test. test ok. as per remedy check for newer software. found no newer software. performed smoke test on the line from purge value to the charcoal canister, plugged charcoal canister filter. found no sign of smoke leak. based of quick test date show only happened 1 time per 40 key cycles. customer might it filling gas with vehicle running or gas cap wasn't tight enoug
After each time the check engine light comes on, I make sure the fuel cap is tight again.
The car is still at the dealership, is there anything I should press them on to diagnose/check?
