a6 3.0 tdi bmk smoking. Need help!

Hi, i have problem with my a6 3.0 tdi. smoking blue a lot and bad smell, mostly at idle. Already change injectors, but still same problem. when i reset default settings for engine, smokes goes away after 10 min idling, after about 1-2 days smokes come back. Any ideas???

Any fault codes? I assume you didn't search so do a search and you'll find results.

No fault codes on engine. Only some bulb errors

Do a search for previous threads.
