Smell of exhaust fumes inside car

[BMWHacker]

I've noticed the last few mornings that there is a smell of diesel exhaust fumes inside the car. Its not really bad but is definitely there and appears to be worse when I'm sitting in traffic.
I did a quick search there and the flexi joint on the exhaust can be the culprit sometimes, or maybe its something else? Any ideas?Thanks

have you checked to make sure its not something as simple as a dirty pollen filter?

Thanks. No, haven't looked at anything yet. Could a dirty pollen filter cause that?
I'm not too familiar with the diesel engines so don't know where to start looking.

You may have an oil leak, a drop of oil on the exhaust will cause that smell. Meanwhile you can switch on the air con and the smell should go away (as air comes through a different route), or otherwise switch off the fan and shut all the vents with the manual controls.

Cheers. Funny you say that about the air con, I usually go around with the air con on all the time and only started turning it off this week, the problem could have been there a while.

Hopefully it's something straight forward, rocker cover gasket or somethin

If the car is an E46 its more than likely a broken flexi joint in the exhaust.

Thanks. It's an e91 320D, I've read they go on the e9x also.
Ah I'll bring it in somewhere and get it checked out rather than googling and speculating :smiling:

I was getting an exhausty smell in the cabin - replaced manky pollen filter and problem solved

Happend twice in the GF mini, both times turned out to be duff injector seals.
