Sq5 blue smoke

[Daveeck]

Hi all,I've recently bought a 2015 sq5 with 70k on the clock,everything has been perfect but recently on random occasions its putting out blue smoke on start up,and very very rarely it will start a little lumpy with a slightly different colour smoke.any ideas guys.there is no power loss or any other issue to mention,oh and its not using any oil.cheers in advance.dave

If you've bought this with 30 days from a dealer then I'd be returning it pronto as you have 30 days to get a full refund. This link might help:

Sadly I've has it more than the 3 months warranty the dealer supplied

I am hoping it's as simple as the pvc valve

Worth a shot. I'd also recommend a diagnostic check.
