Client Type: Residential


Project Overview:

At Euro Auto Tech & Smog, we recently serviced a Mercedes-Benz S450, a true example of luxury performance. As part of its routine care, the client was due for either Service A or Service B, two essential maintenance schedules designed to preserve long-term reliability and efficiency.


Many owners wonder if they can skip these services when their vehicle seems to be running fine—but these are preventative, not reactive. Skipping them increases the risk of unexpected repairs and expensive breakdowns.


Service A Includes:

(Typically every 10,000 miles or 1 year)

– Synthetic motor oil replacement

– Oil filter replacement

– Tire inflation check & correction

– Brake component inspection

– Reset of maintenance counter


Service B Includes:

(Typically every 20,000 miles or 2 years)

Everything in Service A, plus:

– Cabin air filter replacement

– Brake fluid exchange

– Comprehensive systems check


Whether it’s Service A or B, this routine maintenance ensures that the S-Class continues to deliver the refined performance Mercedes-Benz is known for.
