Just inherited a Passat.was wondering if anyone has experience with these cars.it has this slapstick transmission or whatever its called and may need work.I heard it has to have premium gas?any advice would be appreciated. nice car though
You might not believe it but, the most common cause of an EVAP system leak is a faulty gas cap. This is usually due to a cracked/deteriorating gasket inside the cap, or even debris. So my first suggestion is check that thoroughly and go get a replacement. I don't think that is a dealer-only item, (over 80% of the rest of the car is), so pick a generic at any auto parts store, & see if that works.
My impression is that the car already had a check engine light or a code. The place you took it to, hooked up a scanner and found that code. If so, most scanners don't pinpoint specifically "where" it is.
If the gas cap isn't the problem, then you need to check everything down from the cap to the fuel tank, fuel lines, or the EVAP cannister. If you still can't find it, a vacuum or pressure test might be in order, & that requires special tools & equipment. But; before you do that, have the code erased & see if it comes back. It might, might not. I've seen many cars give off false codes, too.
