What each repair involves on the MG, when to inspect or replace, and what our invoices say it costs
The figures are from our invoices. Scheduled maintenance follows the requirements for your car's engine, gearbox and model year; other repairs are assessed from symptoms, inspection and diagnostic results rather than a universal age or mileage. The notes under each repair are general guidance for cars driven in Singapore, not statistics.
Gearbox oil changes for MG cars
This is among the repair work our MG invoices record most often. On the bill, this item typically came to about $250 (GST included; other work on the same bill is not counted).
Gearbox oil lubricates moving parts, carries hydraulic pressure and helps control heat inside an automatic transmission. Degraded or contaminated fluid can show up as delayed engagement, rough shifts, shuddering or noise. Leaving it unchecked can increase wear in the clutches, bearings and control passages, turning maintenance into a deeper repair.
We road-test the car, inspect the fluid condition and trace any seepage before recommending a change. We document the findings and give you an honest quote for the fluid, filter or seal work before it starts, without condemning the gearbox.
Service interval: Follow the interval and fluid specification for your gearbox and model year; they differ between gearbox types even within one model, and we confirm them for your car. Where the maker lists no change for the life of the car, ask us whether a preventive change makes sense for your gearbox and driving.
Maintenance and early warning signs: Use the specified fluid and fill procedure, with the filter where your gearbox has a serviceable one, and avoid hard launches while the gearbox is cold. Fresh fluid is maintenance, not a cure for a gearbox that is already faulty. Early signs: a burnt smell, dark fluid, shifts that have become rough.

Battery replacement for MG cars
This is among the repair work our MG invoices record most often. On the bill, this item typically came to about $350 (GST included; other work on the same bill is not counted).
The battery supplies power for starting and supports the car's electrical systems when demand changes. A slow crank, dim lights, warning messages or erratic electronics can point to low battery strength. Waiting until it fails can leave the car unable to start and place extra strain on the charging system.
We run a battery load test and charging-system test, then check for an electrical drain. We document the readings and give you an honest quote before replacing the battery or repairing the actual charging fault.
When to inspect or replace: The starter battery is tested at every service and replaced on the test result rather than at a set age. Cars with a separate auxiliary battery for the stop-start system or the electronics have that battery tested and replaced the same way, and it is counted in this row. Hybrid drive batteries are a separate matter.
Maintenance and early warning signs: Short trips and daily aircon use are hard on a battery in Singapore; give the car a longer run where you can, switch accessories off before the engine, and park in shade. Early signs: slow cranking, lights dimming at idle, stop-start no longer working, a warning about the auxiliary battery, electrical warnings that come and go.

Spark plugs and ignition coils for MG cars
This is among the repair work our MG invoices record most often. On the bill, this item typically came to about $300 (GST included; other work on the same bill is not counted).
Spark plugs ignite the air and fuel mixture, while ignition coils provide the voltage needed to make that spark. A fault can cause rough idling, hesitation, poor response, a warning light or higher fuel use. An unresolved misfire can send unburnt fuel into the exhaust and damage the catalytic converter.
We scan fault codes, review live misfire data and inspect the plugs and coils before choosing the repair. You see the documented evidence and an honest quote before we replace only the affected items.
Service interval: Spark plugs have a scheduled interval that depends on the engine and plug type, and we confirm it for your car. Ignition coils are replaced on diagnosis, not on a schedule, and a misfire does not by itself mean a coil has failed.
Maintenance and early warning signs: Keep to the plug interval and have misfires checked early, because unburnt fuel can damage the catalytic converter. Early signs: rough idle, hesitation, a flashing engine light.
Oil leak repair for MG cars
This is among the repair work our MG invoices record most often. On the bill, this item typically came to about $2,600 (middle half $1,450 to $3,150, GST included; other work on the same bill is not counted).
Gaskets, seals, covers and housings keep engine oil inside the passages where it protects moving parts. You may notice spots under the car, a burning smell, smoke near the engine or an oil warning. A leak that spreads can lower lubrication and contaminate belts, hoses or mounts, raising the risk of wider damage.
We clean the area and trace the leak from the highest wet point, then confirm whether a gasket, seal, cover or housing is responsible. We photograph the source and give you an honest quote before replacing the leaking part.
When to inspect or replace: Checked at every service and repaired according to the source and severity found, from a weeping seal to a housing. No age makes a leak due.
Maintenance and early warning signs: Change the oil on time to the maker's specification, and fix small weeps before they reach belts, mountings and electrical parts. Early signs: drips under the car, a burning smell after driving, a falling oil level.
