SOURCE: sequence for spark plug leads on a vw polo 1.4 1996
Hello darren625, the firing order will be 1-3-4-2, #1 will be at the front of the block,I am not familiar with volks wagon but you can disconnect the power (to be safe) turn the engine over by hand with plugs out for ease use a piece of stiff wire or small screwdriver in the #1 plug hole and you will feel the piston come up make sure it is on the compression stroke (you will feel air escape) when it is at the top before it starts to travel down that will be tdc (top dead center) the rotor will now be in line with #1 connect wires as per firing order and you should be good to go,hope this helps, good luck

I have changed a few cylinder heads under warranty for this type of problem. The exhaust valve guides wear, this causes the exhaust valve to seat badly, giving low compression. if one cylinder compresion reading is more than about 50 psi below the others, then this warrants head removal. It is quite a job, due to the fact that the camshft id chain driven. If you are up for it then once the head is removed, poor liquid into the exhaust ports and see if it leaks out through any of the exhaust valves.

are the plugs gapped to spec this could cause misfires whick would set off the engine light make sure your plug wires are good and not split for this to may cuase misfires cause the wire is grounding out on the head or the manifold

With the intake where it is this can be verry hard. You may have to pull the intake manifole to get it done. I can pull 1,3,4 but 2 is a problem. Check with a good auto parts store many times they have people with mechanical skills and loaner tools.
