how to change a coil

What engine?? Do you also have the engine ID code? Zee

There is a puller tool but you gently pry up on the coil using the valve cover to work it loose.

IF YOUR JETTA IS A 1.8L THERE IS A GOOD CHANCE THE COILS CAN BE REPLACED UNDER A VW CAMPAIGN, GIVE US A CALL AT 415-241-8100 AND WE WILL BE ABLE TO HELP YOU. TAKE CARE.
