The Mégane II Owners' Club

My 53 megane 1.5dci kicks out smoke on start up blue/white/greyish sorta color but goes once I pull off and only returns if I really floor it.
It's had a new turbo and all relavent pipe work and service light says I have another 2000k miles to go until next one
Iam not loosing power if anything it's bloody quick for a little 1.5 coming from a passat v6 beforehand!
Have no lights on the dash and no other problems so just wondering if I should be worried? I know diesels can put out some smoke so I could be over reacting? All help and info appreciated

What's the mileage? Valve stem seals could be worn allowing a little oil in to the pistons,

Millage is 120k with full history runs perfect and pulls great.

I wouldn't be overly worried if its only really on start up

Surely it is not 2000k, but rather 2k... If it is showing 2k until the service, then it is quite likely that it will need a new turbo again. What oil is in the sump, what filter, was the oil drained through the sump plug? For most of us the oil needs to be changed every 9k miles. Note, about 90% of turbocharger failures are caused by lubrication problems.

Lol sorry yes it's 2k miles until next service but its easy to rest em so its getting a service next week anyway. Not sure about oil change ect no details were given other than a recipt saying oil service dated 2012.

It seems that its progresses from just on start up smoke to smoke when I accelerate or when turbo kicks in its a nasty diesel/oil smell and its more blue now pulls perfect still and power still there as normal,
Are we talking piston rings?
Or oil seals on turbo?
Even tho its had a new one
