Setra S 517 HD: Touring coach, versions and what to check
Setra S 517 HD (from 2012) — a top-class three-axle touring and long-distance coach from the TopClass 500 family. We look at the versions, engines, and what to check when buying used.
S 517 HD in brief
The S 517 HD is a longer, three-axle coach from the Setra TopClass 500 family, with a length of around 14 m. It's designed for large passenger numbers, excursions, and long-distance journeys where plenty of space and luggage capacity are needed.
The S 517 HD is sought-after in the used market for its comfort, capacity, and reliable Mercedes-Benz engines. It's often seen on express routes and touring trips.
Versions — what's the difference?
In the TopClass 500 family, the S 517 HD is one of the longest variants, while the S 515 HD and S 516 HD are shorter. They all share a similar technical base but differ in length, number of axles, and seating capacity.
Early S 517 HD models may have Euro 5 or EEV engines, while later ones have Euro VI. Before buying, make sure you check the emission standard and equipment.
Engines and gearboxes
The S 517 HD is powered by Mercedes-Benz diesel engines, typically around 12.8 litres in capacity. Euro VI versions use AdBlue and a particulate filter.
Gearboxes are either the automated Mercedes-Benz PowerShift or a manual (depending on the configuration). Before buying, test the gearbox and clutch.
What to check when buying a used S 517 HD
Request the full service history and tachograph data. Inspect the body — for dents, wheel arches, door sills, and the boot area.
Start the engine cold and listen for any unusual noises, smoke, or leaks. In Euro VI versions, check the AdBlue and DPF systems.
Check the air suspension, brakes, retarder, air conditioning, seats, and emergency exits. For three-axle models, pay attention to tyre wear and axle geometry.

Names and equipment vary by market and year; we list generally described versions, but check the exact specification in the documents of the specific bus.
