Blue smoke from my Audi A4 TDI... What does is mean?

Burning oil! Possible Turbo Seals but i doubt it. More likely to be valve stem oil seals! How much oil is it using? Could also be piston rings worn but very unlikely! A compression test will tell you if the rings are worn! Get it serviced then have a look at it, if you have to get stem oil seals done it's not too expensive, but if it's passing emissions test i would leave it, you keep topping up oil! Good luck

Its simply burning oil if it was your turbo it would smoke all the time especially when you accelerate.You need to determine how much .How often do you top up with oil it is critical that you don't over fill it should be mid way between min and max marks on dip stick.I own an Audi and don't get all the problems that others seem to refer to Regards Mick.

Rings may be going bad. When the turbo goes you will have alot more than blue smoke. How about big white smoke? RESTORE helped me.

Sounds like the fuel mixture is wrong and needs checking, you're burning some oil too by the sounds of it!!

As steph i said, it's yer rings mate. Fast driving = higher temp = rings expand more = less oil burnt. Stop Start driving = lower temp = rings slacker= oil scraper ring bypassing oil. Ergo, get new rings fitted or may end up needing new engine!

Blue smoke means its burning oil.

Right am no mechanic lol but I always thought blue smoke indicated piston rings failure

Sorry to hear about your Audi!!! Anyone who hates Audi's are idiots and are stupid, it think it could be to do with Burning oil hope this helps

sounds as if you are burning oil get it serviced and stop polluting the atmosphere
