I'm going to show my total ignorance

[darren74]

of car engines here but I can only find TWO spark plugs on my Passat (the two on top of the cylinder head). I'm taking it they have four so where are the other two hidden?

Honestly lads, I don't wear a skirt and make-up, I swear.........

Straight from an American site

"The 1.8T is the perfect engine to learn to replace spark plugs on... access is very easy.

Pop hood open.
Disconnect battery (-) terminal.
Remove engine cover.
Disconnect wiring from coilpacks (4) -- note which plug goes where.
(early B5's only -- unbolt coilpacks (8 bolts total), if applicable)
Pull straight up on coilpacks to expose spark plugs below.
Use canned air to blow-out any debris from the spark plug holes.
Remove spark plugs. (Take pictures of spark tips & post here for an analysis of your plugs)
Apply a very light coating of anti-seize to threads on new spark plugs.
Torque to 22 lb-ft.
Press coilpacks back over spark plugs -- make sure they are in order
(early B5's only: bolt down coilpacks, if applicable)
Plug wiring into coilpacks.
Replace engine cover.
Reconnect battery (-) terminal.
Close hood.

Make sure you use the factory-spec NGK PFR6Q plugs. (They'll run about $10 to $15 each, but you really do need them.)

This should take an hour the first time and 15 minutes every time after that"

On the ADR engine the big coilpack covers 2 with two others attached by regular HT lead.....
