2006 Volkswagen Polo low pressure cylinder 1?

More than likely if sticking , valve / seat will be burnt , meaning head off.

Hi this sounds the same problem as the Seat 12 3 cylinder and the only fix is a new cylinder head as these heads cant be reworked. The problem is burnt valve seats you will usually get the engine warning light on and when you have the fault memory read it says misfire on cylinder ?.
