100,000 miles is a significant marker in the life of any car, but it does not mean you have to get rid of it. Cars that reach 100,000 miles without any problem are well worth keeping, in fact, as it shows that they’re resilient and functional. As one of the most efficient vehicles made, Mercedes are no exception.

When your Mercedes reaches the 100,000-mile mark, it’s essential to take it in for a maintenance check. If you’ve kept up with routine maintenance checks and repairs, you shouldn’t have any unfortunate surprises. Even still, this maintenance check is critical to ensure that your car lasts another 100,000 miles or as long as it can.

What to Do When Your Mercedes Reaches 100,000 Miles

Perhaps you’ve been the one taking care of your car’s oil and basic maintenance up until this point. When it comes to the 100,000 mile service, though, you should always take your car to the professionals. There’s a lot more that will be inspected during this maintenance service, and professional mechanics are the ones that are best prepared to take on the work.

When you take your car in for service at 100,000 miles, here is a list of things you can expect to have inspected.

Fluids

All your fluids will be inspected to ensure they’re at the right levels and not at risk of being clogged. Over time, dirt and dust will build up in your engine and can cause problems if it isn’t taken care of, so this will be inspected while your fluids are checked and refilled.

At 100,000 miles, you can expect most or all of your fluids to be replaced. This includes oil, coolant, transmission fluid, power steering fluid, and brake fluid. 

Belts

Belts are important to the functionality of your vehicle. However, repairing or replacing a broken belt can cost a lot, so it’s important that you have them all inspected after 100,000 miles to ensure they are still in good condition.

During the belt inspections, mechanics will look for signs of cracking, marring, or striping. They will also look for uneven wear, missing ribbing, and brittleness. Depending on what they find, a problem may lie deeper in your car.

Tires

Tires will need to be replaced regularly to maintain traction. At 100,000 miles, you’ll most likely end up replacing your tires. Uneven wear, cracking, and bulging can indicate that your car pulls to one side and needs alignment. In other cases, you may need a tire rotation.

Brakes

Brakes are especially important to have serviced at 100,000 miles. You should have them inspected for signs of wear and tear or replaced. Brake pads will likely be replaced to ensure you have enough padding to stop for the foreseeable future. If you have disc brakes, the rotors will be carefully inspected for pitting, warping, or uneven wear.

If part of your brakes needs to be replaced, it may be best to simply replace them entirely. Your mechanic can advise you on the damage and what they think is the safest solution, but don’t skimp when it comes to brakes, as they’re one of the most important aspects of your vehicle.

Air Filter

Checking and replacing the engine engine air filters is a commonly forgotten maintenance item. It is crucial to keep damaging debris from entering the engine such as sand from road construction. This can damage not only sensors such the mass air flow sensor, but can cause premature engine wear by scoring the cylinder walls. 

Fuel Filter

On modern cars, fuel filters can last 100,000 miles or more. It is important to replace such filters to protect the fuel delivery system. A clogged filter makes the pump work harder and can cause failure. A failed filter can also cause damage to the injectors and other parts of the fuel delivery system.

Spark Plugs

Some vehicles require spark plug changes at 50,000, 80,000 or 100,000 miles. This is important not only for fuel economy, but also to avoid misfires due to work out spark plugs.
