Hey gang. Long time reader, first time poster.
Been driving a Sprinter for a couple years and last December I started noticing exhaust fumes entering the cab, usually through the A.C. It happens once every week or so, usually later in the day. I've written it up each time with the typical mechanic's response being "cannot duplicate problem". Management seems concerned but has not aided in any solution . Several other employees I've talked to experience the same thing, including drivers using the Reach.
Anybody having similar experiences?
