Hi guys.
I have noticed more recently (maybe to do with colder weather) that on cold start I get puff of smoke (white/grey) from the exhaust. The car is a 2009 2.0 TDI Passat B6 Sport - The engine runs sweet and no issues with mpg/oil/fuel or idle.
When the car is warm it does appear to do, only on cold start. No light on dash. I wasn't able to smell it as the smoke only lasts a few seconds.
What could this be? I have access to VCDS but not sure what checks I should make.
