|1. Remove the engine cover.|
|2. Detach the wiring harness.|
Unplug the wiring harness from each of the coils.
|3. Remove the coils.|
Loosen the 8 coil bolts using a 5mm hex key and pull the coils out of the engine.
|4. Replace sparkplugs.|
Check the gapping on each plug and adjust to the recommended gap. NGK recommends a 0.028 gap for the 1.8T engine with the ATW engine code, but anything in the range 0.028 - 0.035 should be fine.
Use the 16mm sparkplug attachment and 6" extension to remove and replace each sparkplug. Optional: apply a light coat of anti-seize on the threads of each new plug. Use a torque wrench to tighten each plug to 22ftlb. Do not overtighten or else you will damage the aluminum cylinder head!
|5. Reinstall coils, wiring harness, and engine cover.|
The Bentley manual recommends tighttening the coil bolts to 7ftlbs (thanks for the info Art!).
