Well we have a 2006 330xi that we bought new. It only has about 25k on it and the ticking has been around quite a bit. I think we have had the engine "bled" at least 3 times with no improvement. I haven't been on e90post in a while and when I checked in I saw this sticky and the SB about the head replacement. I called my SA and mentioned it. He is familiar with the bulletin but mentioned that it has been superceded with a new bulletin that calls for the lifters to be replaced. I am going in on the 17th to get the work done. Hopefully it will work as we plan on keeping the car for many more years.
Any thoughts on head replacement vs. lifter replacement? It looks like some have had heads done and some have had lifters done. It also seems like each procedure has had it's successes and failures!
