Fuel odour issue

[feenix74]

When I am stopped at the lights with my Caddy Life TDI, I will put the ventilation system on recirculate because it will get a bit of diesel exhaust smell in the cabin. I believe this is because the exhaust pipe ends underneath the rear bumper so the exhaust gets caught underneath the body of the vehicle when it is stationary and get dragged into the intake for the ventilation system. It could be the same issue for your TSI but if it definitely fuel odour as opposed to exhaust odour then it might be worthwhile getting that checked because you might have a problem somewhere in the fuel/exhaust system.

You should not need to do this manually as the van will do it automatically. It's a standard feature on Caddys for the reason you have mentioned.

Saying that quite often the auto recirculation flap mechanism can fail. On my van when I stop at the lights I can hear the flap trying to constantly engage. If I hit the button and do it manually it engages with no issues.


As for the OP's fuel smell it could just be the tank was slightly overfilled and is venting fumes. I.e. only fill until the first click of the pump at the servo.
