I have been battling with the P0442 code for a few weeks now.

Had local indy shop go over everything and perform a pressure test on my fuel system. Results indicated all pressure, etc was good.

A few weeks later I had the same code, back to shop, replaced the gas cap. A few more weeks of no code.

Code is back now - anyone have this issue or any tips on putting this to bed?

Thanks in advance!

Cool- I live in Houston, but am in VA 3 weeks a month these days for work.

Adam/Dave over at Eurocharged in Austin would be my go to for something like this.... they'd did the tuning and mods on my C63 and E63 but also di the full baseline and tranny rebuild when needed on our new G55 project. They know the 55's inside and out....

Did you keep the C when you moved into the G ? Plans for the G ?

EVAP systems need to be properly diagnosed. Every car has different procedure based on the code set. In this case, if you want to throw more parts at it, I'd replace Purge Valve
