Audi A4 Timing Belt Replacement Interval for 1.8T 20 Valve Models

BACK TO >> Audi A4 Timing Belt Information Table of Contents

What is the recommended Audi A4 timing belt change interval on the 1.8T engine? Has the in factory recommended Audi A4 timing belt interval for the 1.8T engines changed? Do we recommend the factory interval, or has our experience moved us to recommend a different change interval?

Factory Recommended Timing Belt Service IntervalAudi A4 Timing Belt Change Interval

What is the recommended timing belt change interval for Audi A4 1.8T models? The most recent factory recommend interval is 75,000 miles. Some older scheduled Maintenance Service booklets reference a 105,000 mile timing belt service schedule interval. However, according to the most current manufacturer service schedule information, the interval has been updated to 75,000 miles.

What does Blauparts recommend? When dealing with crucial timing belt service, err on the side of caution and change your Audi A4 timing belt every 75,000 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.

Intended Life-Expectancy of Timing Belt Components

Various Audi A4 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 A4 timing belt and related components last: (1) un-logged engine idle times and sitting 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 75,000 mile interval if the following important steps were taken: Audi A4 Timing Belt Part Life Expectancy

1) Timing belt service was performed using BLAU OFFICIAL O.E.™ components. The same timing belt and timing belt tensioner that were fitted on your Audi A4 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 1.8T 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.
