Despite the warnings that they are a nightmare, I finally got down and done them, took me 40 minutes of my lunch hour, thanks to Snap-On . The old plugs were duff to say the least. Also found the cause of my warning light as well, a split vacumn hose going to the turbo actuator Replaced pipe, carried out 2 drive cycles and the light stayed off.

Congrats, I tried doing mine although on a TD. The first was OK the second was hard, the third was beyond me and the fourth looked even harder.
