I coasted to a stop and tried to start the motor with no luck. We’ve done a half dozen of the 3.2L engines this year and fielded questions about rebuilt heads or installing used engines, and we found the most cost-effective way to repair these for the customer with the best return for us is to repair or rebuild the engine in-house. I was at WOT in 3rd gear at about 4500 rpms when wham i herd a noise and the motor just shut off. You’ll need to quote a couple of hours of diagnostic time to do a compression check and to pull the cam covers and verify that the cams are out of alignment. Replacing the tensioner and repairing the head is not a difficult job, but it’s time-consuming and there are some special tools you’ll need to do the job (see Photo 1). Upon inspection, we can find low to no compression in the right bank cylinders. These six cylinders don’t run very well on just the left bank of cylinders and, depending on how many teeth the chain has jumped, the car may not run at all. The MIL will be lit and cam position codes will be stored. The customer will complain of very poor running and lots of engine noise. The tensioner will fail, allowing the chain to jump. We aren’t sure why, but the failures we’ve seen all involve the right-side cylinder head. Let’s now go into more detail regarding the bad timing chain tensioner symptoms. We believe it’s a lack of maintenance, specifically oil changes, that’s causing some of the failures we’ve seen, so let’s take a look at what’s happening. The 3.2L Audi engine has no less than four chains running the oil pump and keeping everything in time. For years, they had the timing belt turning one cam and a chain with a variable valve timing tensioner running the other cam. Autohaus services the Royal Oak, Troy, Birmingham, Madison Heights, Sterling Heights and surrounding areas.After years of timing belts, Audi and VW switched back to chains on some of their cars in 2005. We can help extend the life of your car and keep it running smoothly.Ĭall 24 to book an appointment. As soon as you see a check engine light or hear a rattling sound at start-up, be sure to give us a call for Audi repair in Michigan. In short, prevention is always superior to cure especially when it comes to high end vehicles like the Audi. If this occurs while you are driving then your pistons may also be damaged not to mention other collateral damage that may occur. Engine won’t start or fails: Of course a broken timing chain will cause your VW to either stop while it is operating or not start at all.When this occurs you can rely on one of our mechanics to use special software to help diagnose the problem so that we can catch a timing chain issue before it destroys your engine. However, when a timing chain is stretched excessively, it can trigger the check engine light. Your check engine light is on: There are so many reasons that a car’s check engine light may be activated that many people unwisely ignore it.Visit our import car repair center in Michigan. If you hear such a noise when your engine is idling, don’t ignore it. This was a common enough problem on 5.7L Hemis (2009-2014 models) that FCA issued a recall notice ( P01) to replace the timing chain guide.A slack chain causes the metal to hit the timing cover which will wear out the chain completely. You do not usually have much time after you hear this noise, before the chain will break. A failing timing chain often makes a rattling noise when it is loose inside the engine. Rattling sounds on a cold start: Noises emitting from a timing chain are one of the most obvious signs that this vital engine component is about to fail.Through years of use, a timing chain can start to stretch which will cause the engine’s timing to be inaccurate and can produce several of these signs: The timing chain allows the camshaft, balance shaft and crankshaft to rotate in synchronization. If it were not present, your high end European vehicle would be useless. If you believe that your timing chain may be failing then we advise you to contact us as soon as possible since a worn out timing chain can eventually lead to catastrophic engine failure.Ī timing chain – which is comprised of a series of links similar to those found on a bicycle chain – is a crucial component of your Audi or VW engine. Although they may be a relatively old technology compared to other components and systems in modern cars, they serve a vital role in keeping your car running smoothly. In the Audi and Volkswagen, the timing chain has been present from the mid 2000s. Since the internal combustion engine was first invented all cars have had a timing belt or chain installed in them.
