[Vwdiesel] Really smells exhaust on startups 04 TDI BEW 182K

[Bryan Belman]

Hi all, looking for suggestions.for the last year the exhaust at startup has been real stinky, dirty diesel smell, not sweet clean burning diesel smell.
Today stumbled on start and threw a code, I have to read it tonight.
I have new seal kits for the special unit injectors in the head, but have not attempted to install them yet.http://www.autohausaz.com/pn/038198051Ccan you send the Unit Injectors out to be cleaned do you think???
They are not like a normal pressure triggered injector at all.
My MPG has been as good as always, 45 to 48.Once it is running for 5 miles or so, the smell is not as bad.
Any thoughts?
