CEL / Carwash
Hey everyone. I’ve encountered a weird issue with my ‘25 GT63 S E-Performance 4-Door. I’ll get a check engine light that just so happens, coincides with the car needing to be washed. I wash it, and the CEL goes away! This has happened 3 times so far. What’s this all about? Has anyone experienced this?? Has my car become self aware and baits me into washing it!?!
Looking forward to what everyone thinks is happening here!

Little update and question. The car has been dirty and washed a couple times since I made this thread. The CEL has not come back.
Question is, does it leave a log or history of the CEL in the ECU’s memory? My buddy has an OBD2 scanner, would this work or do you need XENTRY??
Thank you!
