Back in 2009 we replaced the oil rebreather hose on our 2001 Jetta. In the last week we've noticed an exhaust smell in the car again. Irritatingly enough another piece of hose has worn out, pouring oily residue into the engine compartment.
A few weeks ago we drove to wisconsin and back, averaging 32mpg with the ac running. Keep in mind our car has 184,000 miles on it though.
