R56 Exhaust smell in cabin

Exhaust smell in cabin
So for the past month or so i've been noticing an exhaust smell in the cabin while at idle. Obviously its an exhaust leak, but the question is where? I recently removed the downpipe without replacing the head-gasket. Could a new head-gasket be the fix and cause of the smell? I've also had the CEL light on for almost a month now due to pre cat o2 sensor. The car has 108k miles on it, so is it time for a new o2 sensor? or is the code related to the leak? thanks for any input!

Make the the O2 isn't loose, and check that the DP downs have cracks.
Good luck

I would start with checking all of the above.
CO poisoning is really hard to detect while it is in progress. BTDT on my college rust bucket. By the time you know, your reasoning and reaction times are already impaired. Not a good condition to have while you are behind the wheel. Fix this ASAP.

hey guys, i have the same problem but only at high speed or when i´m reving up above 3500 rpm/ under hard acceleration.
i get that weird smell like something burning, is this problem is cause by DP or exhaust gasket as well?
which gasket do i have to replace?
i have not touch anything on that area

Unless you've replaced your turbo cooling line and/or oil filter gaskets, both are due to be leaking just about now (assuming you are north of 50K miles).
Search the forum threads for pics and description of both failure modes.
