It seems I am always asking these kinds of questions - the ones that show my total ingnorance of ownership of a diesel - but I note that altho I pull my car in to my garage and turn it off before I close the garage door, I always get a diesel smell the next morning in the garage.

Is it normal? What do you do to eliminate or downplay the smell? One thought was some sort of ionic air cleaner. Has this worked for anyone else? Any thoughts?

Thanx all!!

Are you talking about a raw diesel fuel smell? If so, you probably have a leak.

Not really, smells like engine smell (?)

I would look at the air cleaner attachment. A gap would allow fumes to escape or the filler neck to the fuel tank sweating inside the trunk or the drain hole in the body at the filler plugged up, trapping raw fuel outside the fuel tank. Not a very good description of odor. "engine smell?" could be oil or diesel. Does it leak oil (DUH).

actually, there is no oil leaking (never needs oil between 3000 mile fills)

Any diesel smell should be praised highly!!!!! j/k

Seriously, could be a multitude of things, wet fuel return hoses, spin on fuel filter leak, diesel exhaust smell permeating your garage walls....

Not sure if mine smells "dieselly" or not, it doesn't get the garage.

garage smell!! Hmmm... it is there in the morning...

You could switch over to biodiesel and it would smell like doughnuts and waffles!!!!

I took the car to my local repair folks (A&T in Port Chester NY) and they found a defective fuel cap as well as a leak in the fuel line in the engine. Problem solved. Thanks, all...

Check the supply line where it leaves the fuel tank, just inboars of the right rear tire.

1) Check the braided return lines from the injectors for weeping.
2) Check the lines under the tank. They are rubber for a few inchs until they mate with the steel lines that run the length of the vehicle.
