yep. Mine is leaking driver's side exhaust manifold to y-pipe, going to work on it this weekend.
Other common places are:
* the EGR cooler (or the plug if deleted)
* flex joint(s) on the y-pipe
* y-pipe to turbo
Generally, you look for the telltale black soot on the surrounding parts. Or stick a long stick with tissue paper on the end to find where the "wind" is coming from.

How funny, mine has developed a leak somewhere. I can smell it sitting at a stoplight with the driver side window down (passengers do not smell anything) or if the engine has been running and I walk around the front of the grille and fender I can also smell it.
Do not smell it with windows up or thru the vents and boost is normal.
Kind of aggrivating as I can snake my hand all around the joints and flex couplings and cannot feel anything. Even had a buddy revving the engine to make smoke and still didn't see anything.
I suspect the driver's side manifold either at the head or the junction to the y-pipe.

If you are smelling Diesel at a stop light ... it very well may be an exhaust leak ... but, first, it may be worthwhile to check your Fuel Pressure Regulator for a raw-diesel leak. This is the more typical culprit for the diesel smell at a stop light.

My leak us gone though with just one bolt snugged up, but i want to tighten the other one, plus check the pass side bolts too.
The installer of my bulletproof egr and oil cooler must not of tightened them all enough..
A lot more power now too.

I finally found my leak because soot was visible on the bolt at rear of manifold, and I could hear what sounded like an air compressor leaking.
You might check the intercooler connections, i found signs of leaking on the connection under the air box.
Since they are in the front grille area..
Not sure how much smell it might have though.

Yeah, i was napping and not awake.. ignore me...
I've had oily residue there and think it's exhaust - but we know it's clean intake air. realizing its oil from the ccv, but the brain can't help it..
