Does the old BMW X1 have a timing chain?

[BriellaLee]

The old BMW X1 is equipped with a timing chain. Below is a relevant introduction about the engine timing chain: 1. Function: The engine timing chain drives the engine's valve train, ensuring that the intake and exhaust valves open or close at the appropriate times to allow normal air intake and exhaust in the engine cylinders. In some models, such as the Volkswagen Jetta, Bora, and Audi, it also drives the water pump. 2. Effects of timing chain elongation: During high-speed engine operation, the timing chain can stretch, wear, and develop increased gaps. If the timing chain elongates due to increased gaps, it can lead to inaccurate timing and increased noise. If the timing chain wears or stretches due to aging, causing timing misalignment, the valve stems may bend, the piston tops may dent, and in severe cases, the cylinder head may be damaged, preventing the engine from functioning properly.
