Audi A4 Timing Chain Tensioner Install

I will start out by stating that you DO NOT HAVE TO REMOVE THE TIMING BELT TO REPLACE THE TIMING CHAIN TENSIONER. As so many guides including the Audi manual itself states that you have to essentially remove everything, timing belt, bumper, radiator, etc. Just to replace the timing chain tensioner. This is not the case at all and I have performed the repair multiple times in under an hour. The symptoms of a worn out timing chain tensioner are caused by one of two things: The first is the wearing out of the pads or deterioration of the high strength plastic they use. This will cause a consistent grinding, rough idle, low power, and the valves will not be correctly timed at all rpm's. The second type of failure is the hyd piston itself.

If this fails it the timing chain will be fluctuating from completely compressed to complete extension. This will typically cause the timing chain to scrape against the valve cover. If you put your hand on the top of the valve cover you will easily be able to feel the metal on metal scraping.

I will give a general walk through below. • Remove plastic Audi cover • Remove all wiring and coil packs from top of valve cover • Remove bolts that connect the metal pipe to the left side of the valve cover • Disconnect any air or vacuum lines making it very easy to remove the valve cover. When removing valve cover it must be lifted straight up off the studs and can not be angled. • After the valve cover is removed loosen all of the caps for both camshafts. • Remove the first 3 camshaft caps that are nearest to the timing chain tensioner • Be sure to keep tension on the timing belt to avoid any slipping • Remove the bolts that are holding the timing chain tensioner in place • Carefully angle both cams upward lifting the timing chain tensioner with them. This will take a little bit of time to finagle it out but it will come out without damaging any of the cam bearings as long as you take your time. Louisiana Bulletin 1508 Pupil Appraisal Handbook.
