What happens if my Mercedes-Benz E550 spark plugs fail?

When it’s time to replace the spark plugs, don’t delay. These small (but vital!) parts provide the electric spark that your car needs in order to start, and old spark plugs can prevent your car from starting at all. Replace spark plugs on time or about every 30,000 miles or so.

What does a puddle underneath my Mercedes-Benz E550 mean?

Puddles could indicate that your vehicle is leaking coolant, oil, or brake fluid. Ignoring these leaks can lead to permanent engine damage, so address these symptoms ASAP with a tune-up service.

Are hard starts and stops bad for my Mercedes-Benz E550 engine?

You can make your driving habits more engine-friendly. Hard starts and stops can increase the stress on engine parts, especially over many years. Boost your fuel economy and care for your engine by using gradual, smooth starts and stops instead.

Another service option pays special attention to the filters in your E550. Specifically, we replace the fuel filter and air filter. Our third service is a thorough cleaning of the fuel system.
