We can also review the vehicle’s current condition and available maintenance history to help prioritize services. Instead of treating every Mercedes-Benz the same, we consider how the vehicle is driven, its mileage and any known issues that may require attention.

Mercedes-Benz Brake Service and Repair

Your Mercedes-Benz’s braking system plays a major role in both safety and driving feel. If you notice squealing, grinding, vibration, a soft brake pedal, reduced braking performance or a brake warning message, the system should be inspected.

Our Mercedes-Benz brake services include:

• Mercedes-Benz brake inspection

We assess the condition of the relevant components before recommending repairs and can provide suitable options based on the vehicle and how it is used. Whether you need everyday replacement brakes or an upgraded braking setup for a performance build, Parts Plug can help.

Mercedes-Benz Diagnostics and Check Engine Light Repair

A Mercedes-Benz warning light tells you that a control module has detected a fault, but a fault code alone does not always identify the failed component. Proper diagnosis may require testing circuits, sensors, mechanical systems, live data and the conditions under which the fault occurred.

We provide Mercedes-Benz diagnostics for concerns including:

• Mercedes-Benz check engine lights

• Engine and emission-control warnings

• Rough running, misfires and loss of power

• No-start and intermittent starting concerns

• Battery discharge and charging problems

• ABS, traction-control and chassis warnings

• Airbag and restraint-system warnings

• Electronic and communication faults

• Overheating and cooling-system warnings

• Transmission and 4MATIC faults

Our goal is to identify the underlying problem before recommending a repair. This diagnostic-first approach is especially important on modern Mercedes-Benz vehicles, where many systems communicate with one another and a single fault can trigger several warning messages.

Mercedes-Benz Engine Repair and Oil-Leak Diagnosis

Mercedes-Benz engines deliver excellent performance, but age, mileage, heat and maintenance history can contribute to oil leaks, cooling-system concerns, ignition problems and other mechanical issues. Early diagnosis can often prevent a manageable repair from becoming a more serious failure.

Our Mercedes-Benz engine repair services include:

• Valve-cover and valve-cover-gasket replacement

• Oil-filter housing and oil-cooler leak repair

• Oil-pan gasket and oil-leak repair

• Cooling-system pressure testing

• Water-pump and thermostat replacement

• Turbocharger and boost-leak diagnosis

• Intake and vacuum-leak testing

• Intake-valve carbon cleaning for applicable direct-injection engines

• Timing-chain, timing-belt and timing-system diagnosis

• Crankcase ventilation system repair

• PCV and oil-separator diagnosis

• Engine mount replacement

• Compression, leak-down and mechanical engine testing

If your Mercedes-Benz is leaking fluid, overheating, misfiring, smoking, making an unusual noise or displaying a check-engine or engine warning, contact us to arrange an inspection.

Mercedes-Benz 9G-TRONIC, 7G-TRONIC, Transmission and 4MATIC Service

Smooth power delivery depends on the condition of the transmission, differentials, all-wheel-drive system, axles and related driveline components. Mercedes-Benz vehicles use several transmission and 4MATIC system configurations, so the correct service procedure depends on the exact model and drivetrain. Symptoms such as harsh shifting, delayed engagement, vibration, shuddering, clunking or fluid leaks should be investigated before the concern becomes more severe.

Our Mercedes-Benz transmission and driveline services include:

• 9G-TRONIC and 7G-TRONIC fluid and filter service

• Automatic transmission-fluid and filter service

• Transmission pan and gasket replacement

• Transmission leak diagnosis

• Transmission fault diagnosis

• Valve-body, conductor-plate and shift-quality diagnosis

• Manual transmission and clutch service

• Differential-fluid service

• 4MATIC driveline service where applicable

• 4MATIC and all-wheel-drive diagnosis

• Driveshaft and centre-support-bearing repair

• CV axle and wheel-bearing replacement

• Differential and driveline diagnosis

We determine the appropriate service or repair based on the Mercedes-Benz model, transmission type, symptoms and condition of the fluid and related components.

Mercedes-Benz Suspension and Steering Repair

Mercedes-Benz vehicles are known for controlled handling and responsive steering. Worn suspension or steering components can cause clunking, looseness, vibration, uneven tire wear and a noticeable decline in ride quality.

Our Mercedes-Benz suspension and steering services include:

• Control-arm and bushing replacement

• Ball-joint and tie-rod replacement

• Shock and strut replacement

• Coil-spring replacement

• AIRMATIC air-strut and air-spring replacement

After identifying the worn components, we can recommend an appropriate repair for a comfortable daily driver or a more performance-focused suspension setup.

Mercedes-Benz Battery, Electrical and Charging-System Service

Modern Mercedes-Benz vehicles rely on battery-management and energy-control systems that require the correct battery type and installation procedure. Some applications also require battery adaptation, system resets or auxiliary-battery diagnosis.

We provide:

• Mercedes-Benz battery testing and replacement

• Battery adaptation and system reset where required

• Auxiliary-battery diagnosis and replacement

• Alternator and charging-system testing

• Parasitic battery-drain diagnosis

• Starter and no-start diagnosis

• Lighting and electrical repair

• Sensor, switch and wiring diagnosis

• Control-module and network fault diagnosis

If your Mercedes-Benz displays a battery discharge warning, has difficulty starting or develops intermittent electrical problems, our team can test the system and identify the source of the concern.

Mercedes-Benz Air Conditioning and Climate-Control Repair

If your Mercedes-Benz’s air conditioning is not cold, airflow is weak or the climate-control system behaves inconsistently, we can inspect and diagnose the system.

Mercedes-Benz climate-control services may include:
