A rattling noise coming from the engineĪs you can see, the issue is a serious one.If the timing chain loosens, it can lead to the following issues: The timing chain tensioner is what keeps the chain tightly wound to the pulleys and gears, and has notoriously failed in many Volkswagen cars-it has even led to multiple class action lawsuits over the years. Older models of VWs especially experience premature timing chain failure, and the problem is usually related to a failed chain tensioner. While all timing chains eventually wear over time and must be replaced, Volkswagen timing chain defects are a known issue in the automotive community. The Defective Timing Chain in Volkswagens If your jewelry chain snaps, you might lose an expensive charm if the timing chain snaps, your engine can undergo severe damages that often lead to total failure. Think of a gold chain-the metal is malleable, especially when consistently exposed to hot conditions, and will stretch to the point of eventually snapping. Just like a bike chain, your VW’s timing chain will wear over time. Ultimately, the timing chain generates enough power to smoothly control ignition processes. The various different linkages on the chain lock into place with the connections on the camshaft and crankshaft, which controls the cylinder head valves, pistons, and rods in the combustion process.
