Just bought myself a 2015 A6 3.0TDI Quattro 272ps Avant… absolutely love it.
Car has 70k miles and a very comprehensive service history, including two S Tronic gearbox services (thankfully!!). I noticed however in cold start (for example first one in the morning) a puff of blue smoke, that isn’t there on warm starts or when driving on hard acceleration (done this with someone driving behind me). Car drives grand. Just curious as to why this is happening, should I be worried and what or where should I be looking? Obviously have some time on my side with the dealership I bought her from to cover under the legal 30 day warranty, so want to get to this now rather than later. Thank you advance everyone.

Usually a sign a few of the glow plugs have failed, a code read MAY show but sometimes they have to be removed to be checked BUT should never be reused anyway, one snapping on refitting really ruins your day.
