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.

Why us
Marque-specific experience
Its systems are interlinked; one sensor fault can surface as four error messages. We start from a correct reading before any part is changed.
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.
Mercedes service in Riyadh needs a workshop that knows the generations apart: an M274 E-Class is not an M256 mild-hybrid S-Class. We start from the VIN to fix the correct fluids, parts and procedures.
Common Mercedes concerns include air suspension dropping after long parking, upper-engine oil leaks, shift shudder and weak summer A/C. Each symptom follows a different inspection path before parts or work are recommended.
Services
Specialist work
These jobs need model-level knowledge, and they are the most requested on a Mercedes in Riyadh.
AIRMATIC air suspension repair
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.
Oil leaks and timing chain
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.
Module coding and programming
Any new Mercedes module needs coding to the car's data, otherwise fault messages keep returning. We code with approved tools and update software.

Equipment
How we diagnose this marque
Marque-specific platforms and workshop equipment work together to isolate the cause.
01
Marque-level diagnostic tools
Every European marque has its own diagnostic platform that reaches all modules, not just the engine ECU. We read stored and live faults with their conditions, compare them against factory values for that exact model, and keep a copy of the report before and after the work so you always have a clear reference.
02
Lifts and wheel alignment equipment
Checking suspension means lifting the car and loading each joint individually, not shaking a wheel. After any suspension or steering work we align on measuring equipment and hand over the before-and-after readings, because one angle out of range is enough to eat a tyre and change high-speed stability.
03
Temperature-controlled gearbox filling
A modern gearbox does not accept estimated filling. The correct level is set at a specific fluid temperature with a calculated quantity; too much or too little later shows as overheating, low pressure or a shift jolt. We change the filter and gasket, clean the magnets in the same operation, then reset adaptations and road-test the car.
04
Refrigerant recovery, weighing and leak testing
We first recover and weigh the existing charge to learn how much the car actually lost, since a shortfall always means a leak. We trace it at joints, condenser, compressor seal and evaporator; after the repair we vacuum out moisture and charge the exact weight and oil specification. These steps are the difference between cooling that survives a Riyadh summer and a refill that fades in weeks.
05
Measured body and structural repair
A European body is engineered to absorb impact energy in a calculated way, so every accident repair starts by measuring the body points against factory data before any pulling. Partial respray uses a colour match verified with a test card inside a spray booth, and once finished we set the alignment and recalibrate cameras and radar if they were affected.
06
Organised parts store and trusted sources
We stock fast-moving parts for the marques we serve so your car does not wait days for a filter or a gasket. Parts are either genuine or from the original equipment manufacturers themselves, with the type stated in the report before work starts; anything not available locally is ordered with a stated lead time before you decide.
Technicians
Who works on your car?
Technical decisions based on the VIN, measurement and documentation, not guesswork.
01
A technician per marque
Your car goes to a technician used to that specific marque, not to whoever is free.
02
Work starts from the VIN
The VIN fixes the generation and the correct fluid and part spec, preventing look-alike part mistakes.
03
Photo report before work
You see photos and scan readings before approving; nothing outside the approved list is carried out.
04
Genuine or spec-matched parts
The part type is stated in the report, and you choose between genuine and approved equivalent.
05
Post-repair handover check
After any repair we rescan and road-test the car before handover.
06
Documented follow-up after handover
The handover records completed work and follow-up items, making later reviews easier against the vehicle history.
FAQ
FAQ
Do you repair air suspension or replace it?+
We locate the leak first. Many cases only need an air spring or compressor repair; we replace the full system only when genuinely needed.
Do you keep the service record?+
Yes — every visit and part is logged in your vehicle record and service indicators are reset after each job.
Do you provide scheduled Mercedes-Benz service?+
Yes, using the correct fluid, filters and interval for the model and Riyadh conditions.
Do you diagnose Mercedes-Benz before repair?+
We begin with module scanning and physical measurement, then explain the result before ordering parts or starting work.
