It’s common for people to sell their cars before the 100,000 mile mark and invest in a newer car. However, as this trend seems to have slowed down, more and more people are continuing to drive their well-loved cars long past the 100,000 mile mark until the car simply can’t go on.

While routine maintenance and servicing should be something you’re familiar with, you might be wondering if it’s worth continuing after 100,000 miles or what parts should be serviced at the 100,000 mile mark.

What Should Be Serviced Once Your Audi Hits 100,000 Miles?

Fluids

At 100,000 miles, you should replace all fluids in your Audi: oil, transmission fluid, coolant, braking fluid, and power steering fluid. This is because, over time, dirt and debris will build up and can clog your engine and damage it. Replacing old fluids with new, clean fluids will keep your engine healthier and ensure that it continues to last.

While your fluids are being replaced, make sure to check for any leaks that may need to be sealed or fixed.

Serpentine and Timing Belts

It’s vital that all belts in your Audi are in good, working condition, as repairing a broken belt can be expensive and time-consuming. Check all your serpentine belts and your timing belt. Having any one of these belts break while you’re driving or out of a service range can be disastrous, so make sure to stay on top of things and check them regularly. 

Signs that it’s time to replace your belts include brittleness, cracking, missing ribbing, striping, marring, or uneven wear. 

It’s likely that your timing belt will break at some point, especially if you routinely drive in climates with extreme weather temperatures. While replacing it will be expensive, it’s better than waiting for it to break when you’ll need to pay for a tow truck and additional roadside assistance.

Tires

Your tires will need to be replaced over time, especially if you do lots of driving. Keep an eye on the tread and replace them before they wear down too much. Old tires can cause problems and make driving in slightly adverse conditions dangerous.

If you do have to replace tires, either replace all four or two. Never replace an odd number of tires, as this may lead to your car pulling unnaturally to one side or cause other problems. If you choose only to replace two, choose either the front pair or the rear pair and not one side or the other.

Brakes

At 100,000 miles, it’s likely that your car has already had its brakes worked on or replaced. As you continue driving your car, ensure that they are inspected and tested. Your brakes will wear down again and may need maintenance or replacement again.

Other Things to Service

Along with the major things listed above, the hinges and moving joints of your doors and seats should be inspected too. You’ll also want to service your air filters and fuel filter. Finally, ensure that your spark plugs get a good inspection and your battery, making sure that the terminals haven’t been corroded and the battery acid is at a decent level.

Conclusion

As long as you’ve been having routine maintenance done to your vehicle, it should be in good condition and won’t need any significant repairs. However, when you do take it in after 100,000 miles, you should expect a more comprehensive inspection of the vehicle.
