N52 spark plug and coil change how to

[Ed Doe]

It's the valvetronic motor that controls valve lift not timing. Basically it acts instead of a butterfly throttle body.

Erm, no it doesn't..

Corrected for you

Don't try and use a standard short plug socket with an extension bar, unless you have a professional one that locks to the extension bar the socket will end up being left on the spark plug at the bottom of a deep hole. You can buy a long spark plug socket with a magnetic end to hold the spark plug from Halfords. I'm going to get one for my 2.0. I'm not sure if the plugs are the same size but mine are 16mm AF so I'm going to get one of these

Got it. I am now trying to remove the rubber ignition coils, but they seem to be very hard to pull.
There doesn't seem to be a way to remove 4 out of 6 of them, even if I keep twisting left and right while pulling.
I had to stop as I think there must be a better way to do it or use some sort of tool.

Another thing that I noticed is that right above 2 of the ignition coils there is a light metal frame attached to the top of the engine which is used to hold the bolts needed for the plastic cover.
I believe I will need to remove that frame if I want to access those 2 plugs - and that needs another type of wrench.

When you lift the clip to remove the coil pack, put a large metal screwdriver through the oval holes of the clip and pull on the screwdriver.
