This is VERY bad and at the very least will result in a valve job, if not the destruction of the engine. This is why changing the timing belt is one area of maintenance that should never be skipped or stretched out. Always replace the belt according to the vehicle's maintenance schedule. Audi recommends changing your timing belt every 100,000 On the 2.0T, TFSI (and TSI) the tensioner for the lower chain has a design defect that causes it to fail. When it fails, the timing chain skips a few teeth (timing is now wrong), and the valves can collide with the tops of the pistons, destroying your engine. This usually happens when you start the engine.

Normally, timing chains are designed to last the life of the car and the rest of the engine. But, the life of the engine is sometimes defined by pistons and valves running into each other when the timing chain breaks. Another failure mode of a timing chain is stretching. That causes the chain to come off the cogs. Vay Tiền Trả Góp 24 Tháng.
