What each repair involves on the Q5, 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.
Cooling-system repairs on the Audi Q5
25% of the Q5 registrations in our records had at least one invoice involving this work (11 of 44, 13 invoices in all). On the bill, this item typically came to about $700 (middle half $650 to $850, 8 recent priced bills, GST included; other work on the same bill is not counted).
The water pump circulates coolant, the thermostat regulates its flow, and the radiator releases heat while hoses and seals keep the system closed. A warning, sweet smell, damp patch or rising temperature can point to lost circulation or a leak. Waiting can turn a contained cooling fault into overheating and wider engine damage.
We begin with an ODIS scan, pressure-test the cooling system and use tracing dye where needed, with every finding documented. You receive an honest quote before work starts, and we replace the failed cooling part or seal rather than unrelated components.
When to inspect or replace: Water pumps, thermostats, radiators and hoses are inspected and pressure-tested and replaced when a fault is confirmed; some engines also list a scheduled water-pump replacement, which we check for your car. Coolant itself is changed on the maker's schedule for your engine.
Maintenance and early warning signs: Top up only with the specified coolant, and stop as soon as a temperature warning appears. Early signs: a sweet smell, a coolant level that keeps dropping, a wet patch, a temperature gauge climbing in traffic.

Spark plugs and ignition coils on the Audi Q5
25% of the Q5 registrations in our records had at least one invoice involving this work (11 of 44, 12 invoices in all). On the bill, this item typically came to about $200 (12 recent priced bills, GST included; other work on the same bill is not counted).
Spark plugs ignite the fuel mixture, while ignition coils supply the voltage needed to create that spark. A fault can feel like hesitation, shaking, weak pickup or uneven idling, and it may trigger a warning light. Continued misfiring can strain the exhaust system and cause wider damage.
We use ODIS misfire data, inspect plug condition and test coil output at the affected cylinders. We document the result and give an honest quote before work starts, then renew the faulty plug or coil instead of changing sound ignition parts.
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.

Gearbox oil changes on the Audi Q5
20% of the Q5 registrations in our records had at least one invoice involving this work (9 of 44, 10 invoices in all). On the bill, this item typically came to about $250 (10 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 control. Worn or contaminated fluid may be accompanied by rough shifting, hesitation, noise or signs of leakage. Delaying attention can increase internal wear and spread contamination through sensitive components.
We check gearbox data and fluid temperature with ODIS, inspect for leaks and assess the drained oil, then record what we find. We quote honestly before work begins and service the oil and filter where suitable, addressing any identified seal or component fault instead of condemning the whole 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.

A routine visit stays lighter when inspection finds maintenance needs alone, while cooling, ignition or gearbox faults involving added parts and access make the work more involved. The invoice summary describes past workshop visits, not a quote for your car. We diagnose the Q5, explain what it needs and give an honest quote before work starts.
