W12 plug change guide/ walk through
after seeing David had done a service i decided to do the same and make a little guide. i know there are very few W12 D3's on the forum but hear it is any way
12 Plugs were not cheap around £210 for a full set I did mine one side at a time. first thing to do is take off the maf and the connection pipe do this on both sides Remove the Two T30 Torx head bolts and the half will split, the hoses are just slipped on and easy to remove http://i866.photobucket.com/albums/a...025_115250.jpg i found a broken pipe so i fixed that while i was there you can see where the oil from the breather was leaking a tad so i cleaned that up too On to coil removal They are simple to take out only pushed in place they are new as they were done under a recall just before the new engine was fitted Repeat for all the plugs Hear you can see the 2011 Stamped engine The repared pipe back in place Reverse to put it back together And now for the other side Same as the other side only this time you will have to remove the oil filler spout to be able to remove the number 7 coil pack one 10MM bolt as you can see You can see the different angles that form the W between pistons Again reverse the steps to re assemble Its quite easy and may save you quite a fair amount of money to do it yourself audi would charge £500+ for this simple process I will do some more when i get a chance maybe the full oil change and air filters.

Good guide, £210 for a set of plugs! I think I paid £90ish for my set of genuine Audi RS 2 plugs (which is what I use in my RS 6) and I thought that was pricey. What NM did you tighten the plugs to?

I've just come across this plug change guide and wanted to thank daviesbike for such clear information. I've googled W12 plug changes often and never seen this - best info yet for when I eventually attempt it on my nearly 60,000m SWB W12 - it''ll be due at around 70k. Well done - even the torque values! Don't suppose you remember how the old ones looked compared with the new? It's such a big job one is tempted to leave it a bit longer than the manfacturers spec!
