What We Offer

Our Service Range

Detailed descriptions of every service we provide at our Dunoon workshop. Each starts with a clear assessment and a discussion of findings.

Brake inspection at Zenvyxa
Safety Systems

Brake Inspection & Repair

A functioning brake system is central to safe vehicle operation. Over time, components wear in ways that aren't always obvious until a problem becomes significant. Our brake inspection covers the entire system — from the pedal feel down to the discs and beyond.

We start with a visual assessment during which we check disc pad thickness, disc condition, caliper operation, and brake hose integrity. Where fluid condition is involved, we test its moisture content using a refractometer to determine whether a change is due.

What This Service Covers
Front and rear brake pad measurement
Disc thickness and surface condition assessment
Caliper inspection for sticking or seizure
Brake hose and line inspection
Handbrake cable or electronic parking brake check
Brake fluid moisture content test
Signs Worth Having Checked

A squealing or grinding noise when braking, a brake pedal that feels softer or needs more travel than usual, vibration through the pedal, or a vehicle that pulls to one side under braking are all worth having inspected. These don't automatically mean major work is needed, but an assessment will clarify the situation.

Inspection findings will be shared with you before any repair work is authorised. We won't carry out brake work without your explicit approval.
Engine diagnostics
Engine Systems

Engine Diagnostics

Modern vehicles generate fault codes whenever the engine management system detects a value outside its expected parameters. These codes are a starting point, not a conclusion — interpreting them correctly requires knowledge of the specific vehicle and its operating conditions.

We use diagnostic equipment that reads codes across multiple vehicle systems, not just the engine ECU. This gives a fuller picture when multiple warning lights are active or when a fault is intermittent.

What This Service Covers
Full OBD2 fault code read
Live data monitoring of sensor values
Visual engine bay inspection
Freeze frame data review
Written summary of findings and recommended next steps
A diagnostic session produces findings and recommendations. Any repairs identified will be quoted separately before work proceeds.
MOT preparation check
Legal Compliance

MOT Preparation Check

An MOT test checks that your vehicle meets minimum road safety and environmental standards. The preparation check we offer is not the MOT itself — it's an internal review of the main items the official test examines so that you know what condition your vehicle is in beforehand.

If we identify items likely to result in a failure, we can either address them prior to the test or make you aware so you can decide how to proceed. This is not a guarantee of an MOT pass.

What This Service Covers
Lighting: headlamps, indicators, brake lights, fog lights
Tyre condition and tread depth
Windscreen, wipers, and washers
Brake performance assessment
Steering and suspension visual check
Exhaust system condition and emissions review
Seatbelts and horn
This is a preparation check, not the official MOT test. Results are advisory. The official test is conducted by a separate authorised body.
Chassis & Handling

Suspension & Steering

The suspension and steering systems affect how your vehicle handles, how tyres wear, and how stable the vehicle is at speed. Worn components often develop gradually, which means changes in handling can go unnoticed until the wear becomes significant.

Our inspection covers the key components on both the front and rear axles. We use a vehicle lift to access the underside and check items under load conditions where appropriate.

What This Service Covers
Shock absorber and strut condition
Coil spring inspection
Bush condition (control arm, anti-roll bar)
Ball joint assessment
Steering rack and tie rod ends
Wheel alignment check
Any parts found worn beyond acceptable limits will be discussed with you before replacement is considered.
Drivetrain

Clutch Repair

A clutch is a wear component — it will eventually need attention in any manual transmission vehicle. The rate of wear depends on driving style, vehicle weight, and how the clutch is used in stop-start conditions.

Our assessment covers both the mechanical and hydraulic elements of the clutch system. We check pedal feel, engagement point, and look for signs of slipping or difficulty engaging gears.

What This Service Covers
Pedal travel and engagement point check
Slipping assessment under load
Hydraulic slave and master cylinder inspection
Clutch fluid level and condition
Clutch disc, pressure plate, and flywheel replacement (if authorised)
Clutch replacement involves significant labour time. We provide a clear quote before any disassembly takes place.
Electrical Systems

Battery & Electrical Systems

Modern vehicles rely on stable electrical supply for functions ranging from the engine management system to comfort features. Battery deterioration is one of the more common causes of starting problems and unexpected warning lights.

We test the battery's actual charge capacity rather than just its voltage, which gives a more accurate picture of its condition. We also test the charging system to confirm the alternator is maintaining the correct output.

What This Service Covers
Battery load test (CCA and capacity)
Alternator output voltage check
Starter motor draw assessment
Lighting circuit check
Sensor and fuse inspection
Battery replacement where required
Complex electrical faults may require extended diagnostic time. We'll agree on the scope with you before proceeding.
Routine Maintenance

Oil & Filter Service

Engine oil lubricates the moving parts within the engine and helps manage operating temperatures. Over time and mileage, oil degrades and its ability to protect the engine reduces. A scheduled oil change at the manufacturer's recommended interval is one of the most straightforward ways to maintain engine condition.

We use the oil viscosity and specification recommended for your vehicle. This matters more on newer engines where tolerances are tighter and where the wrong specification can affect performance or economy.

What This Service Covers
Engine oil drain and refill to specification
Oil filter replacement
Sump plug and washer check
Top-up of screenwash, brake fluid, and coolant where required
Service interval reset (where applicable)
We'll confirm the oil specification for your vehicle before the service. If your car uses a specialised or extended-drain oil, this will be reflected in the quote.
Engine Thermal Management

Cooling System Service

The cooling system manages engine temperature by circulating coolant between the engine, radiator, and heater circuit. A failing component in this system can lead to engine overheating, which can cause significant internal damage if not addressed.

Coolant degrades over time and its protective properties — including freeze protection and rust inhibition — reduce. Most manufacturers recommend coolant renewal every two to four years.

What This Service Covers
Coolant condition and freeze point test
Pressure test of the cooling system
Radiator and hose visual inspection
Thermostat operation check
Water pump inspection where accessible
Coolant drain, flush, and refill to specification
If a leak or component failure is identified during inspection, we'll discuss the findings before proceeding with repairs.
