Have you noticed that nearly everything single person who has done a DIY 4.4i valve timing ....gets the same exact code p0011 and p0021? The tool used to adjust the timing wheel (bimmer tool rental), is not accurate enough. I think a better approach is tif someone developed an electronic timing device that assists in timing the timing wheel to the cps. Or a way to fine tune it using software after getting close with the tool. There are just too many ways for the timing wheel tool to be off because of engine block metal casting discrepancies and the such. It truly is a sensitive adjustment.
