Tiguan TSI spark plug gap

[nat225]

Could it be the improper install of spark plugs for coil packs caused the trouble in the first instance. Probably when install the second time may have done a better job and problem solved I believe 0.8 is the correct value for GTI version of TSI engine and boost level.

I am running 0.6 mm gap with no issues but of course with a tune.

the first install was done the same way, torque wrench to 18ft lbs, BUT the gap was per NGK factory (0.8mm) out of the box.

the 1-1.1mm gap for CCTA engine (Mk6 GTI) was based on this:
