Does the Bora engine use a timing belt?

The Bora does not use a timing belt. The Bora is equipped with the EA111 engine, and the Volkswagen EA111 engine uses a timing chain. More information about the timing chain used in the Volkswagen Bora engine is as follows: 1. The timing chain installed in the Volkswagen Bora effectively addresses the shortcomings of timing belts. The timing chain, made of relatively strong steel, can solve wear issues, as metal is stronger than rubber. 2. The timing chain in the Volkswagen Bora's engine generally does not require replacement, but it is necessary to regularly inspect the condition of the timing chain to avoid chain stretching, which could prevent the engine's timing system from operating normally and affect the car's performance. 3. Advantages and disadvantages of the timing system: Timing belts are quieter, have less transmission resistance, and lower transmission inertia, which can improve the engine's power and acceleration performance, and are easier to replace. However, the downside is that they are prone to aging, have a higher failure rate, and result in relatively higher maintenance costs for the owner.
I've been driving for over a decade and am quite familiar with engine structures across various models. The timing systems used in different model years of the Bora indeed vary. For instance, the older 1.6L engines mostly used metal timing chains, which generally don't need replacement under normal driving conditions. However, newer Bora models like the post-2019 1.5L engines have switched to rubber timing belts that require periodic replacement. I've seen many cases where the belt suddenly snaps while driving, bending the valves instantly, with repair costs easily exceeding ten thousand yuan. It's recommended to inspect the belt condition every 6 years or 80,000 kilometers. If you notice fine cracks or frayed edges, replace it immediately. Don't wait for a breakdown to regret it—this is one expense you really shouldn't try to save on.
Last time when I accompanied my friend to pick up the new Bora, I specifically asked the salesperson and confirmed that the 2023 model indeed uses a timing belt for its 1.5L engine. From my own experience, this type of rubber belt is most vulnerable to oil leaks. If the engine seals age and cause oil to contact the belt, its service life can be halved directly. For routine maintenance, I recommend checking the belt condition during every minor service by lifting the hood, focusing on whether there are any transverse cracks on the surface. Additionally, it's normal for the belt to emit a brief squeaking sound during cold starts in winter, but if the noise persists while driving, the tensioner pulley should be inspected.
After researching various sources, it was found that the Bora's timing system has undergone phased changes: models before 2010 generally used chains, then from 2010 to 2018 some 1.4T models switched to belts, and by 2019 the entire lineup had adopted belt designs. The advantage of belts is that they are quieter and lighter, but their durability is indeed inferior to chains. Typically, you should start paying attention to the belt's condition at 60,000 kilometers, and it is recommended to replace it by 80,000 kilometers regardless of its condition. When replacing, remember to change the tensioner pulley as well—if this component fails, a new belt can be ruined in just three months.
