Last friday my AOS blew completely. Thanks to this forum I was able to come back from the brink of the abyss and all is well. Most of the AOS posts show or describe a unit that bolts to the side of the engine and has a bellows on the bottom. For the 2003 the unit bolts down directly onto the variocam area without bellows and has an L shaped tube that fits onto the side of the engine. I went with the cut the old hose and replace it route using the hose clamp for the new hose connection to the side of the engine. The newest revision number is .01 and cost about $78. I had the .00 on my 2003. Please be careful with the vacuum tubes if you choose to remove and clean the horizontal manifold sections and throttle. I strongly recommend this if you had a thick white smoke, you will surely have standing oil in the manifold sections. I was about a half quart low after this trial. Also note that I got a lot of fault codes upon starting after cleaning. I also got a lot of white smoke upon restart for 5 minutes or more, but it did not foul or cause additional codes. All fault codes cleared out and everything is lovely. I have a Durametric diagnostic tool. I offer photos for your edification. There are more and I will answer any questions you may have.
