Thread: Where are the air filters located on a D4

Manual is 16 bucks on this site. Engine air cleaner unlikely to smell in car.

Try it on recirculation. If it doesn't smell when you do that. Check out the air tract. Just under the windscreen. There is a drain there somewhere. If it's full of crap it'll smell inside and eventually flood

Some brands also make a black pollen air filter which is carbon. Helps kill smell

This will just be cooking bugs in the cooling pack, or on the engine itself. Once that starts cooking you’ll smell it everywhere!

One little thing people don't generally know.. smell is molecular. So what? you ask. So, if you smell grasshopper, you have actual grasshopper in your nose. Thing is, 'molecular' means the smell can pass through pretty much anything. (This is why it's impossible to fool dogs at airports.) Smell can pass through glass.

All the posts below are worth following up, as long as you understand that they won't work once you understand smells. Think of this: a fart stinks, yes? Well, it's best not to remember the molecular thing at that point.... 'Cos what you are smelling.., do I need to draw you a picture?

Wash your filters and enjoy the grasshopper. I would.

I get a stink in the D4 sometimes when using the screen cleaner, but not at others. I've checked the pollen filter and that's OK. Would think that if bugs were jammed under the windscreen it would pong all the time.
Meanwhile the Cook accuses me of being the source......

What are you using for screen wash. That can pong sometimes. Stick your nose over the reservoir filler and have a wiff.

Using "bugs off" or something like that. Doesn't appear to come from there though.
