9G-TRONIC transmission service
Mercedes gearbox fluid differs by model and must be filled at a set temperature. We change fluid, filter and pan to spec and test the internal control unit before condemning the box.
Mercedes service in Riyadh by technicians used to its engines and systems, with dedicated diagnostic tools.
A Mercedes needs a technician who knows its detail, not a general workshop. We work on M254, M256, M276 and M278 engines, 9G-TRONIC gearboxes, AIRMATIC suspension and the car's interlinked electrical systems.
Every car gets a full scan, then a clear report with the fault, its cause and the cost before we start. We use genuine or approved-equivalent parts and warrant the work we do.

A car sitting low is usually a leaking spring or valve, not the whole system. We test each corner and replace only the failed component.
M272/M276/M278 engines commonly leak at the valve cover and oil cooler, and stretch their chain with mileage. We measure chain timing before opening anything.
Any new Mercedes module needs coding to the car's data, otherwise fault messages keep returning. We code with approved tools and update software.
| Item | Interval | Note |
|---|---|---|
| Engine oil and filter | Every 10,000 km | MB-approved spec for the model |
| Gearbox fluid and filter | Every 60,000 km | Earlier for city use |
| Air and cabin filters | Every 20,000 km | Critical in Riyadh dust |
| Brake fluid | Every 2 years | Absorbs moisture and weakens braking |
| Air suspension check | Yearly | Corner height and system pressure |
Module reading and coding after replacement
Advanced module parameter work
We locate the leak first. Many cases only need an air spring or compressor repair; we replace the full system only when genuinely needed.
Yes — every visit and part is logged in your vehicle record and service indicators are reset after each job.
Yes, using the correct fluid, filters and interval for the model and Riyadh conditions.
We begin with module scanning and physical measurement, then explain the result before ordering parts or starting work.
