Any one know how to change the spark plugs?

Its very involved on a 1.8t beetle because there are soo many vacuum hoses and solenoids on top of the coils. You need a 5 and 6mm allen wrench, and a 10mm wrench (or socket) and the normal spark plug socket and ratchet as far as tools go.
I would also reccomend replacing all those 1/8" vacuum hoses on top of the valve cover and intake manifold as they are a common failure and cause of check engine lights.

I just did mine and it did not seem that involved. It was my first attempt at it, and all I had to do to get to the ignition coils was flip over the vacuum hose assembly once I disconnected the electrical connection on the left side. After that, just basic spark plug changing. Granted, I did not replace the hoses. But, if I start having check engine lights for that, I will do just that. :)

im glad you posted this, my dad actually tried to change mine yesterday and he couldnt find them underneath all that stuff, i thought he was playing, this is horrible lol
