Tuesdays have become my official "tinker with the Audi" day since i have no morning classes. In the past few weeks i've installed a new (lower temp) thermoswith for the fan, a radiator flush, oil change, installed my rear mudflaps. Nothing big mind you, just my little projects. Yesterday was, again, full of progress with a spark plug change and a Pentsion flush. The plugs had been in for ~30-35,000 miles, the coil boots were origonal and warn, and the gasket around the coil cover leaked; so everything was replaced. The plugs looked decent, but i could see where oil leaked to them from before i did the vcg. The Pentsion on the other hand, came out pretty nasty, almost the color of dirty motor oil. I used the procedure written up by one of the A8 guys and was happy with the outcome. All-in-all the tinkering took a little over an hour. Not bad for a nice Tuesday morn. Just thought i'd share.

The old plugs, with a new one. Excuse my crappy camera...

One plug, the picture makes it look worse than it was. There was little carbon, with a nice white/light brown color.

that's easy. i'm going to do that next week. where did you get your fluid?

but you can get it from an audi or porsche dealer. It costs a lot through them though. ecstuning.com has it for around $15, which is pretty cheap, but you have to pay shipping. It is a pretty easy procedure, the hard part is not spilling the old fluid all over the place.
