A low-mileage Golf that only ever got oil changes

The owner came to us from another shop. Their previous mechanic had changed the oil regularly, but nothing else had been looked at, so they asked us to go over the car properly.

At 60,000 km it's easy to assume a car is barely broken in. But this Golf is 13 years old, and rubber, brake parts and filters age with time as well as with distance. A car that's driven little and sits a lot can be harder on its parts than one that's driven every day.

Engine air filter: badly clogged (photo 1, new filter on the left). The engine breathes through this filter, and one this loaded restricts airflow, costs power and response, and makes the engine work harder for the same result.

Cabin air filter: it looked like the original. Everything you breathe inside the car passes through it. An old one cuts heater and A/C airflow, makes it harder to clear fogged windows in winter, and stops trapping dust and pollen.

Brake rotors, front and rear: heavy rust (photo 3). Low-mileage cars that sit get this. Rust builds up on the braking surface and around the edges, the pads only clean part of the face, and the car brakes on less metal than it should. It shows up as noise, pulsing and longer stops.

Left rear brake caliper: brake fluid leaking past the piston seal (photo 4). This is a safety problem. The system slowly loses fluid, the fluid soaks the pad and ruins its grip, and that wheel stops braking properly. Left alone, it keeps getting worse.

Transmission pan: seeping at the gasket (photo 2). It isn't urgent yet, but running low on transmission fluid leads to harsh shifting and overheating, and a transmission costs far more to fix than a gasket.

Tires: dry-rotted, with cracking down the centre of the tread (photo 5). The tread depth was fine because the car hasn't covered many kilometres, but the rubber has aged out. Old rubber hardens and grips poorly, especially in the wet, and the cracks can keep spreading until the tread separates.

• Replaced front and rear brake pads and rotors
• Replaced the leaking left rear brake caliper
• Flushed and replaced the brake fluid
• Replaced the engine air filter
• Replaced the cabin air filter

• Reseal the transmission pan when the winter tires go on
• Replace the all-season tires in the spring, before they go back on the car

The brakes were the priority, so they're sorted now: new pads, rotors, the rear caliper, and fresh fluid, since fluid this age has absorbed moisture. The car stops straight and quietly again. The pan reseal is booked in with the winter tire changeover, so it doesn't mean a separate trip, and the dry-rotted all-seasons come off for winter anyway.

None of this was hidden. It was all visible with the car on the hoist, but no one had looked. An oil change on its own isn't maintenance. That's why a multi-point inspection comes with every oil change here: we check the fluids, brakes, tires, belts and suspension, and you get a list of what's fine, what to keep an eye on and what needs doing now, so you can plan the work instead of finding out on the side of the road.
