Hi I have a vaxhall astra 1.7cdti ecoflex estate life mk5 2010 model. Giving blue smoke out of exhaust when driving mainly. It's done 160k miles
Not sure what can it be??
Valve seals?
Head gasket??no signs of any leaks checked this.
Turbo?
Dpf filter ??
Any help would be much appreciated

@kingimy123 160K and blue smoke would lead me to believe you are having issues with the Turbo. The very first thing you want to do is a compression test and a leak down test. That way you at least get an idea about the condition of your rings etc. , as well as your valves. It could rule out your valves, seals, rings etc. Let us know what you find out.

Main cause of blue smoke - your'e burning oil
Worn valves or guide seals
Turbocharger issues
Failure to change your oil or oil filter regularly enough
Damage or wear to pistons

There is no simple answer for your question. There is certainly no way that you could fix this if you are not a mechanic. You need to take the car to a trained, experienced mechanic to get it evaluated.
