Thanks for the information. So I have not talked with the service rep yet but I'm wondering if they play the "the recall could not have caused the filler neck problem". Also you say that a leaking fuel flange(I believe this is the exact recall item?) caused the purge valve to overwork and it fails. Wonder if that new purge valve should also be covered under the recall fix?
So in the video I posted the smoke is coming out of the filler neck area and you think that is happening because of a bad purge valve? Is there any long term damage I need to worry about now after I replace the purge valve? She has about 105k miles on her and I've been wondering if its time to trade her in. The oil leak the tech pointed out in the video also worries me errrr. I'd love to keep the LR4 as long as possible but don't want to throw money away if there is no hope.
I have not seen the P0442 code yet BUT my LR4 does have a P0456 code atm.
Again thank you for taking the time and posting this. I'll check out your thread.
P0456 is another EVAP leak code. No damage, but it’s possible that the charcoal canister is saturated to the point where you’ll start eating purge valves every so often until it’s replaced. Mine might be, I’ll know if I get this problem again.
The smoke comes out of a vent at the filler neck, that’s how it is supposed to work. The smoke isn’t going anywhere bc there isn’t a leak, and you can’t test the purge valve operation without an expensive computer system… even the GAP tool we all use doesn’t do it.
There’s zero chance you’ll be able to get the dealer in the hook for this stuff. The EVAP system is just one big chain of parts that depend on each other, so if something fails there’s usually another piece trying to compensate. Is what it is. I had to replace the whole system on Silverado a few gears ago.
