Pre-purchase car inspection Arncliffe
Your trusted protection against dodgy sellers in Southern Sydney. We bring a thorough, technologically sophisticated vehicle inspection directly to the car’s location.
Why Arncliffe buyers face unique risks
Arncliffe is a diverse and growing suburb in the St George area of Southern Sydney. With Arncliffe train station, nearby Sydney Airport, Brighton-Le-Sands and the M5 Motorway, it is popular with families, professionals and commuters—and a constant flow of used vehicles changes hands in Arncliffe, Banksia, Rockdale and surrounding areas.
The Princes Highway, Forest Road and the M5 see heavy traffic and constant use. That creates a market where vehicles with hidden mechanical problems can easily be passed on to an unsuspecting buyer.
Degreasing and steam cleaning can make an engine look dry even when a leak will return within days.
Thick oil additives can temporarily reduce the symptoms of front-seal or rear-main-seal leaks.
Tyre shine can make old tyres look new, while rotating tyres can hide uneven wear.
Cheap scan tools can turn off warning lights, while stored or pending codes may still reveal the problem.
The danger of oil seal leaks and worn tyres
The front seal and rear main seal keep oil inside the engine. When they fail, oil can contaminate other components, and repairs are labour-intensive: the front seal may require removal of the crankshaft pulley and timing components, while the rear main seal requires removing the transmission.
Worn tyres reduce traction, increase stopping distances and raise the risk of a blowout, especially in wet conditions. A professional inspection is the best way to uncover leaks and safety issues before you hand over your money.
Find the leak before you take the car onto the M5.
Skipping an inspection could leave you with oil seal leaks, worn tyres or another major mechanical problem. You could be driving on the Princes Highway or the M5 when the engine loses oil pressure or a tyre blows out. A pre-purchase inspection means no expensive surprises after the cash has changed hands.
How we inspect cars in Arncliffe
We believe in complete transparency. Here is what happens when you book the mobile pre-purchase car inspection Arncliffe buyers trust.
Pre-arrival preparation and database check
We gather the seller’s contact number, your details and the registration number. We check whether we have inspected the vehicle before, run a history check for written-off status, theft, finance and previous accidents, and prepare a make-and-model-specific checklist. For an Audi A3, we pay close attention to the front seal, rear main seal, valve-cover gasket and other common oil-leak points.
Arrival and initial visual assessment
- Exterior walkaround for panel gaps, paint mismatches, accident repairs, rust and body condition.
- Underbody check for oil, coolant and transmission-fluid leaks, including fresh oil, residue and stains.
- All four tyres checked for uneven wear, cracking, bulging and other damage, with tread depth measured.
- VIN verification across the dashboard, door jamb and engine bay.
- Interior and under-hood checks for excessive wear, leaks, damaged hoses, cracked belts, neglect or a recent cover-up clean.
Pre-start diagnostic scan
- Professional-grade scan through the OBD2 port with ignition on and engine off.
- Stored, pending and history codes across engine, transmission, powertrain, body and other modules.
- Specific oil-pressure code checks, which can point to a significant oil leak.
- Odometer comparison with mileage stored in other modules, plus battery-health analysis.
Thermal-camera cooling-system inspection
Our professional thermal imaging camera maps heat distribution through the cooling system. A cold spot on the radiator can reveal a blockage that may lead to overheating—one of the tools that sets this inspection apart.
Engine start and comprehensive live-data analysis
- Live data from major systems, including oil pressure, MAF, coolant temperature and engine-oil temperature.
- Current and historical misfires by cylinder, transmission temperature and slip.
- Historical overheating events.
- Where applicable: DPF soot load, EGR commanded-versus-actual position and turbo boost pressure.
- Engine noise checks at idle and during gentle revving for knocks, taps and rattles.
Comprehensive physical and mechanical inspection
- Front seal: seal area, crankshaft pulley and timing cover checked for oil leakage.
- Rear main seal: seal area, transmission bell housing, engine-oil level and oil condition checked for evidence of leakage.
- Underbody: full inspection with a low-profile creeper, including oil residue on the exhaust and UV dye testing where applicable.
- Tyres: tread depth, uneven wear, date codes, cuts, bulges, cracks, spare tyre, jack and tools. The Australian legal minimum tread depth is 1.5mm.
- Suspension, steering and brakes: shocks, springs, ball joints, tie-rod ends, control-arm bushes, sway-bar links, steering rack, pads and discs.
- Other systems: engine and transmission mounts, vital fluids and leak detection throughout.
On-road test drive with dynamic monitoring
We use a test route around Arncliffe that includes local streets, bumps and highway speeds on the Princes Highway or the M5. We monitor oil pressure under load while assessing engine performance, transmission shifts, steering and handling, chassis and suspension feedback, tyre stability, braking and any burning-oil smell.
The verdict and report
If you are present, we show you the issues and explain their severity on the spot. If you are not present, we send a detailed written report by the same evening, supported by high-quality photos and videos, so you can make a clear buying decision.
How we found front and rear seal leaks on an Audi A3
A client asked us to inspect a used Audi A3 at a private property in Arncliffe. It looked stylish and well-maintained, with a tidy interior and a clean paint job. The seller claimed it was recently serviced, had no leaks or issues, ran perfectly and had great tyres.
Eight checks that exposed the truth
History code revealed low oil pressure
The pre-start scan found a stored history code related to the engine oil-pressure system, even though the warning had been cleared.
Recent cleaning raised a red flag
The unusually clean engine bay had been degreased and detailed, suggesting someone may have been hiding an oil leak.
The front seal was leaking
Oil was seeping from behind the crankshaft pulley, a classic sign of a front seal leak.
The rear main seal was leaking
Fresh oil was leaking from between the engine and transmission, the location of the rear main seal.
The oil level was significantly low
The dipstick confirmed the car was losing oil through both seal leaks.
The tyres were due for replacement
All four tyres measured below 2mm, two were at the 1.5mm legal minimum, the fronts showed uneven wear and the date codes were over five years old.
Live data showed low oil pressure
Oil pressure was lower than normal, especially at idle, confirming the problem found during the physical inspection.
The test drive confirmed the problems
The car felt unstable around corners and a burning-oil smell suggested leaking oil was reaching the hot exhaust.
The result
The vehicle had a front seal leak, a rear main seal leak and tyres due for replacement. Repairing the front seal could cost $500–$1,500, the rear main seal $1,500–$3,000 or more, and four tyres $600–$1,200. The total repair bill could exceed $3,000–$6,000. Oil leaks can lead to catastrophic engine damage and may create a fire hazard on the exhaust, while worn tyres create a serious safety risk.
This is what we do every day in Arncliffe: protect buyers from oil seal leaks, worn tyres, major mechanical issues, odometer tampering and hidden accident damage.

The cost of a pre-purchase inspection in Arncliffe
The cost depends on the vehicle’s complexity and exact location. Our prices start from $250 and go up to $450. That is a small price to avoid buying a car with oil seal leaks, worn tyres or another major mechanical problem.
A small price compared with one major repair.
When a single seal replacement on a European car like an Audi A3 can cost thousands of dollars, an inspection is the cheapest and best insurance policy you will ever buy.
