When buying a car, especially a used car, many questions arise. One of these concerns the timing belt replacement. Owners of a VW Tiguan often ask: “Does my Tiguan have a timing chain or a timing belt?”. The answer isn’t always clear, as it depends on the engine and model year.
The Importance of the Timing Chain and Timing Belt
Before we go into detail, let’s first clarify the function of these two components. Both the timing chain and the timing belt have the important task of synchronizing the camshaft and crankshaft in the engine. This synchronization is crucial for the valve train and thus for the smooth running of the combustion process. A defect in these parts can lead to serious engine damage.

VW Tiguan: Which Engines Use Chains and Which Use Belts?
Generally speaking: Most petrol (gasoline) engines in the VW Tiguan are equipped with a timing chain. Diesel engines, on the other hand, typically use a timing belt. However, there are exceptions, so checking the vehicle documents or using the Vehicle Identification Number (VIN) to identify the exact engine is advisable.
Advantages of the Timing Chain:
- Durability: Timing chains are generally lower maintenance and need to be replaced less frequently than timing belts.
- Robustness: They are more resistant to wear and external influences.
Advantages of the Timing Belt:
- Quieter Operation: Timing belts operate more quietly than timing chains.
- Cost: Replacing a timing belt is usually less expensive than replacing a timing chain.
What Happens in Case of Failure?
A broken timing belt or a stretched timing chain can lead to engine damage because the engine timing no longer works and it can result in what’s called a ‘valve collision’.
Regular Inspection is Important
Regardless of whether your VW Tiguan is equipped with a timing chain or a timing belt, you should adhere to the manufacturer’s recommended inspection intervals.
