Audi A3 & TT Timing Belt Replacement Info for 2.0T FSI

Audi Engine Bay 2.0T FSIEverything you need to know about Audi timing belt replacement on 2.0T FSI; which was used in the following Audi models:

  • 2008-2009 Audi TT (US) 8J chassis
  • 2006-2008 Audi A3 (US) 8P chassis

The inline mounted 2.0T FSI engine is driven by a timing belt system which links the cylinder head, camshafts, and crankshaft to run in sync. This Audi A3 TT timing belt system consists of a wear resistant, high strength, corded/molded rubber timing belt (a.k.a. Audi A3 TT toothed belt). There's also an assortment of tensioner and idler rollers to guide and tension the Audi A3 TT timing belt.

It's very important to service your 2.0T Audi A3 TT timing belt. The timing belt, tensioner, and idler components eventually reach the end of their recommended service life. The A3 TT 2.0T FSI is an interference engine (a.k.a. non-clearance engine). If the Audi A3 TT timing belt fails, the timing belt system that links the cylinder head, camshafts, and crankshaft no longer run in sync. Close tolerance engine designs allow for the cylinder head valves to hit the top side of the pistons. Audi A3 TT timing belt failure on these engines usually results in catastrophic engine damage (i.e. bent valves and in some cases cracked pistons).

Audi A3 TT Timing Belt Service Change Interval

Audi A3 TT Timing Belt Change IntervalWhat is the recommended Audi A3 TT timing belt change interval on the 2.0T 16 valve engine? Has the in factory recommended Audi A3 TT timing belt interval for the 2.0T engines changed? Do we recommend the factory interval, or has our experience moved us to recommend a different change interval?

The most recent factory recommend interval is 110,000 miles.

What does Blauparts recommend? When dealing with crucial timing belt service, err on the side of caution and change your Audi A3 TT timing belt every 90,000 miles. It is our recommendation to closely inspect all timing belt components before the recommended interval. Play it safe, changing your timing belt may seem expensive. However, choosing to exceed your timing belt service interval is risky and can lead to unknown repair costs that will far exceed typical timing belt replacement service cost.

It is also interesting to note that the 2.0T service maintenance schedule calls for a timing belt and tensioner inspection at 60,000, 80,000, and 100,00 miles. The inspection is done by visually inspecting the timing belt and physically spinning and testing the tensioners and idlers bearings for excess play.  To properly visually inspect the belt and physically spin the tensioners, the car needs to be in the timing belt service position. Considering the amount of labor just to get the car into service position, it is best to consider the cost savings and perform the complete timing belt service at the same time.

Intended Life-Expectancy of Timing Belt Components

Audi A3 TT Timing Belt Life ExpectancyVarious Audi A3 TT timing belt component life spans. In our own service facility, we've seen a few original timing belts last over 100,000 miles and others ready to break before 75,000 miles. In addition to mileage there are other factors that age the timing belt and related components. The following are some reasons why you see the difference in how long an Audi A3 TT timing belt and related components last: (1) un-logged engine idle times and siTT ing in traffic; (2) warm-up time in cold weather; (3) environmental climate factors; (4) related engine maintenance that may have been overlooked.

Keys to the long-life of your new timing belt components after timing belt replacement. Make your new parts last! You can expect your new BLAU OFFICIAL O.E.™ components to last the specified 90,000-110,000 mile interval if the following important steps were taken:

1) Timing belt service was performed using BLAU OFFICIAL O.E.™ components. The same timing belt and timing belt tensioner(s) that were fiTT ed on your Audi A3 TT from the factory, which are engineered to meet factory interval requirements.

2) Timing belt service was performed by an experienced competent ASE certified Audi mechanic who is familiar with your specific engine 2.0T 16 valve engine.

3) Factory service procedures must be strictly followed. Even if installing the best parts, using improper procedures can shorten their life span. Incorrect installation or missteps during timing belt service are often done without intent and aren't noticed until further down the road. Fortunately, some common mishaps are noticed after re-assembly and during the final engine rotational timing sequences.

Looking to Buy A Used Audi A3 TT and Wondering About Timing Belt Replacement?

Many people who are looking to buy a used Audi A3 TT 2.0T 16 valve start researching the cost of replacing the timing belt. It's best to purchase a car that comes with service history records from the previous owner. Owners who value their car and took care of it will have a record of all service history, an indication of the vehicle's overall shape and reliability. The importance of service records is indisputable. A seller without any service records, is looking to take advantage of the "inexperienced" buyer, making more money at their expense.

Inspecting a timing belt that "seems fine" isn't enough. You'll also want to confirm when the last timing belt service was performed with the appropriate documentation. Don't just take the word of a seller saying "Oh, I think I changed it around 30,000 miles ago." Assumptions and no documents mean RISK. Calculate the cost of timing belt replacement into your purchase price if they don't have the records.Audi A3 TT Timing Belt Replacement Service Records

What to Replace While Changing the Audi A3 TT Timing Belt on the 2.0T FSI 16 Valve Engine

Audi A3 TT Timing Belt Replacement Diagram 2.0TIMAGE DESCRIPTION: Apart from the timing belt itself the Audi A3 TT 2.0T 16 valve engine's timing belt system consists of 4 serviceable timing belt components. One is the water pump that is driven by the timing belt. Second is the two small fixed idler bearing, both being centrally located on the timing belt system. Third is the timing belt tensioner which provides variable spring-loaded tension to the timing belt. All these components work in sync with each other to guide and tension the timing belt.

Before going through the significant work of taking your car apart for timing belt replacement, please consider the following:

Looking To Save Money... "Can I Just Replace the Timing Belt?" Simply changing the Audi A3 TT timing belt isn't enough. Why? Around the timing belt service interval (90,000 - 110,000 miles), due to age the integrity of the tensioner(s), damper, water pump, and other seals and o-rings are at the end or very near the end of their service life. Some individuals make the mistake of only replacing the timing belt. Then, 10,000-20,000 miles later, their new timing belt fails due to tensioner, idler bearing, or water pump failure.


Why replace your Audi A3 TT timing belt tensioners during timing belt service? Just as the timing belt has a designated service life and subsequent change interval, so do the tensioners and idler bearings. It's true that timing belts can get old, begin to crack, and eventually fail. However, it is just as common for the timing belt tensioners and/or idler bearings to fail, thus causing timing belt failure.

How can the tensioners cause a timing belt to fail? Most tensioner bearings contain a set amount of grease behind the seal. This grease provides ample lubrication and ensures tensioner reliability for the designated life span (90,000 - 110,000 miles). During engine operation, constant thermal temperature fluctuations eventually cause the bearing's grease to breakdown and loose it's lubricating properties. Over time, this results in unwanted bearing play and eventual seizure. If a timing belt tensioner has too much play or seizes, the timing belt can become misaligned, or begin to 'burn up' and shred, causing engine failure. Thermal temperatures also affect the timing belt causing the material composition of the belt to change and accelerates its life span, often resulting in premature failure.

Water Pump

Why replace your Audi A3 TT water pump during timing belt service? It makes sense from a labor standpoint since timing belt dis-assembly is required for water pump replacement. The water pump is driven by the timing belt and contains an internal sealed bearing that has a life span similar to the timing belt, tensioner, and idler bearings. The internal bearing and seals of an Audi water pump can weaken and is the primary reason why a water pump eventually fails.


Why replace your Audi A3 TT thermostat during timing belt service? The engine temperature is controlled by the thermostat. The 2.0T engine's thermostat is located inside a thermostat assembly. Near the end of its designated service life the thermostat spring temper changes. This causes the thermostat to open too much allowing the engine to run cooler, resulting in poor fuel optimization, decreased fuel economy, and less horsepower.

Do I need special tools? Can I do it without the tools?

When replacing the Audi A3 TT timing belt on my 2.0T model, do I need the special tools? On older single-cam Audi engines it is possible to achieve general timing without the special tools. However, on modern interference Audi engines this is very risky. Special tools were designed for a reason. They maintain proper timing relationship between the camshafts and the crankshaft position. Slight variations in timing or orientation can result in catastrophic engine damage (e.g. bent valves).

This isn't the area of vehicle maintenance to cut corners or try to save time. On these Audi models, in order to achieve 100% proper cam to crankshaft timing, special tools are necessary. When the timing is off just a degree or two the check engine light could appear, and a lack of performance is often noticed. Remember, you're performing a crucial maintenance repair. If done incorrectly, catastrophic engine damage will result.

The Audi 2.0T FSI engine has no specific tools to hold the crankshaft and camshaft in an exact place well changing your timing belt. The engine timing marks are referenced by the timing alignment marks placed by the factory. There are some special tools that can make your timing belt service much easier. This would include special tools for counter holding the crankshaft sprocket well loosening and tightening the crankshaft bolt as well as the camshaft sprocket bolt. Other beneficial tools include the cam and crank seal removers, cam and cranks seal installers, radiator valance support tools, eccentric wrench for properly tensioning the timing belt tensioner, and a 2-jaw puller for popping the tapered camshaft sprocket loose.
