How do you stop exhaust fumes entering the cabin of a Porsche 944 when the windows are open?

Your rear hatch probably needs adjusted or you need a new hatch seal. This happened to me after I painted my car. If this was the case, the fumes would be there all the time. I 'm led to believe that, in the 944, when you open a window or the sunroof, it creates a differential pressure in the cabin. This then tries to 'suck' hot engine air (not exhaust) through the base of the gear lever. If the gaiter is well sealed, it just gets very hot. Any gaps, and the hot engine air comes in. Brilliant - open a window (at speed) and it gets hot and/or smelly. The real question is - how do we stop it? I'm no engineer but I should have thought it possible to make an air deflector to fit under the gear lever. demonpedro

How does the heater work on a Porsche 911 1982 sc 3.0?

You have an exhaust leak. Either a busted manifold, bad gasket, hole in your exhaust system. You fix it by repairing the leak. Ignore this and you may end up killing yourself. Get this fixed ASAP, if not sooner. In the mean time drive with your windows down.

How do I know if the exhaust is broken?
The next time you have the vehicle serviced ask to have the exhaust system inspected. Most service stations will give the vehicle a safety inspection (during an oil change) which would include the exhaust system at no extra charge. If you suspect there is a problem with the exhaust now, don't wait. Carbon monoxide fumes could be getting into the cabin area which can be deadly.
