What each repair involves on the GLB, 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 servicing on the GLB
42% of the GLB registrations in our records had at least one invoice involving this work (22 of 52, 24 invoices in all). On the bill, this item typically came to about $250 (23 recent priced bills, GST included; other work on the same bill is not counted).
Gearbox oil lubricates moving parts, carries heat away and supports smooth hydraulic operation. Deteriorated or contaminated fluid may show up as hesitant engagement, rough shifts or shuddering. Leaving it can increase heat and wear, turning maintenance into internal repair.
We begin with an XENTRY scan, then inspect the fluid condition and check the gearbox for leaks. We document the findings and give an honest quote before work starts, renewing only the fluid, filter and seals the service requires.
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.

Brake pads, discs and wear sensors on the GLB
37% of the GLB registrations in our records had at least one invoice involving this work (19 of 52, 21 invoices in all). On the bill, this item typically came to about $1,350 (middle half $700 to $1,600, 19 recent priced bills, GST included; other work on the same bill is not counted).
Brake pads press against the discs to slow the car, while wear sensors alert the driver when material is running low. Squealing, grinding, vibration or a dashboard warning can signal that something needs attention. Delaying an inspection can damage usable discs and reduce braking confidence, making the repair broader.
We read any brake alerts with XENTRY, measure the pads and discs, and inspect the sensors and calipers. Our honest, documented quote is shared before work starts, and we replace only the worn or faulty brake parts.
When to inspect or replace: Pads and discs are measured at every service and replaced by thickness and condition against the limits for your car, not by mileage. Discs are judged on the same measurement, not on a fixed number of pad changes.
Maintenance and early warning signs: Brake early and gently, leave a gap so you roll instead of stopping at every light, and use engine braking on long descents; stop-and-go traffic wears pads and discs faster. Early signs: squeal, grinding, a pulse through the pedal, a wear warning on the dash.

Battery replacement on the GLB
35% of the GLB registrations in our records had at least one invoice involving this work (18 of 52, 19 invoices in all). On the bill, this item typically came to about $350 (18 recent priced bills, GST included; other work on the same bill is not counted).
The battery provides starting power and keeps the car's electrical systems stable when demand changes. Slow cranking, dim lights, warning messages or lost settings can point to weak supply or a charging fault. Waiting risks a no-start and can place extra strain on the charging system.
We use XENTRY alongside a battery health and charging-system test to separate a tired battery from a connection or charging fault. We document the results and give an honest quote before work starts, then correct the confirmed fault rather than changing parts by guesswork.
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.

A visit moves up or down with the work confirmed, the condition of related parts and whether routine service uncovers a separate fault. The published statistic is a guide from recorded invoices, not a quote for your GLB. We inspect the car and give you an honest quote before work starts.
