Ive bought 1.2 petrol polo 08 has smoke problem . Stuck servo i think as its only breathing from bottom end ?

Welcome to the Forum.

 

To be able to give you an accurate answer, I believe we really need more information.

Not sure what you mean by a 'stuck servo' - Are you saying that there is no braking assistance? or that the brakes will not release?

With regards to the smoke, are we talking about exhaust smoke, or could you be referring to crankcase breathing?

 

If you have BLACK exhaust smoke, that would indicate that the mixture is too rich.

 

If you have BLUE exhaust smoke, that would indicate that you are burning engine oil

 

If you have WHITE exhaust smoke, that  could be indicating water or coolant entering the combustion chambers

 

Let us know if it is exhaust smoke, and we will attempt to guide you as to the probable cause.
