I get this funny smell when I start my 2003 TD5... It smells like the smoke when a cap gun or fire cracker goes off... the diesel also seems to burn with a pretty foul smell at times.... Thought I read somewhere that a sticky injector can cause a bad smell.... any thoughts?

Have you looked to see if any odd puffs coming from exhaust?

I was having some puffs of white smoke on cold start ups, but that seems to have cleared up for the most part... or only happens very infrequently.

Anyway to diagnose? How do you deal with that?

White smoke is unburnt fuel, it would be worth checking the injectors. Put it on a reader. It sounds like an intermittent problem. Check injector loom for oil ingress, known Td5 issue.
Diesel bug produces a black sludge in tank, filter, fuel lines. Result is poor performance or not going at all.

I occasionally get a bit of black smoke when I accelerate under load, but just small puffs and clears up soon as my RPM;s come up and nothing compared to how my old VW diesels would smoke.

Black under load normal. Do check the harness at the plug under the seat next to battery for oil contamination.

Glow plugs faulty for cold start smoke, remember td5 only has 4 glow plugs.
Black smoke is not normal when running, unless it has been messed with.

I am actually dealing with two different smells.... a gun power type smell on start up and then a funky smell when running

Has your Cat been removed, I replaced mine after getting really smelly exhaust and its now sweet as a nut again. I also replaced the EGR, removing it made no difference to economy or performance.

I just Googled your question and it said it can make the exhaust smell differently to normal. I think that is with older fuel and fuel with water in it.

Had my TD5 from new 2005 it has always had a smell on start up but not unpleasant rather a sweet aromatic but dissipates in 5 seconds?

I don't believe so... I at least never did, and don't believe the previous owner did... but would have to crawl under to confirm, ha.
