Exhaust fumes in air vents

[Daviesmith]

Hi I just had my 2011 VW Polo in the garage for a service and MOT . Since I got it back I can smell fumes coming out of the air vents but only when I reverse. Any idea what it could be ? I looked under the car to see if the exhaust was damaged but it seems ok .

Thanks

I can't see the connection to make the fumes. But take it back and get it checked.

Are you sure it's exhaust fumes? It could be that they've dripped a little oil on to the exhaust manifold and you're smelling it burning off as it heats up. Or, a crank-case vent hose left disconnected etc.

As said above, take it back.
