Expert mobile vehicle checks that protect you from dodgy sellers, hidden DPF faults and expensive diesel repairs before you buy.
Granville is a vibrant, diverse suburb with a rich industrial history, excellent transport links and a strategic position near Parramatta, Auburn and the M4. That popularity means a constant flow of vehicles changing hands across Granville, South Granville, Holroyd and surrounding areas.
Industrial estates, residential streets and heavy traffic on Parramatta Road, Woodville Road and the M4 can be tough on vehicles. Some unlicensed backyard dealers operate from homes or industrial units, buy problematic cars, add a cosmetic touch-up and sell them as private vehicles.
Skipping an inspection could leave you stranded on Parramatta Road or the M4 after losing power or entering limp mode. Professional inspection is your absolute protection before you buy.
We believe in complete transparency. This is the step-by-step process behind the mobile pre-purchase car inspection Granville buyers trust.
We gather seller details, your name and email, and the registration number. We check our database for previous flags, written-off status, stolen-vehicle reports, finance and accident history, then prepare a make-and-model checklist such as the DPF, EGR, turbocharger and boost system on an Audi Q7 diesel.
At a private home, property or car park, we check panels, paint, repairs, rust, underbody leaks, exhaust soot, VINs, interior wear, hoses, belts, turbocharger, boost pipes, intercooler and signs of a cover-up clean.
Our professional computer scans engine, transmission, powertrain, body and other modules. On diesel vehicles we investigate DPF, EGR, regeneration, turbo and boost codes, compare odometer readings across modules and assess battery health.
Thermal imaging examines the radiator, hoses and engine block. Cold spots can reveal blockages that may cause overheating. This is a tool that 99% of other inspectors in Granville do not use.
We monitor MAF, coolant and oil temperature, misfires, transmission temperature and overheating history. For an Audi Q7 we check DPF soot and ash load, regeneration history, EGR commanded versus actual position, EGR cooler, boost pressure, turbo vanes and injector balance.
We inspect the DPF and exhaust for cracks, leaks, soot and tampering; the turbocharger for damage, oil and shaft play; boost pipes, intercooler, sensor and wastegate; plus valve-cover, oil-filter, oil-pan, rear-main and turbo oil-line leaks, suspension, fluids, brakes and tyres.
We use a route around Granville with city streets, bumps and highway speeds on Parramatta Road or the M4. We monitor DPF regeneration, boost under load, engine performance, transmission shifts, suspension feedback and braking.
If you are present, we show you the issues and explain whether the car is worth buying. If you are not, we send a detailed written report with photos and videos by the same evening.
The prestige diesel SUV looked immaculate and the seller claimed full service history, excellent fuel economy and no leaks. Fault codes had been cleared, a highway drive had likely forced a DPF regeneration and the engine bay had been cleaned.
Stored codes showed DPF restriction, low boost pressure, EGR malfunction and a previous low-oil-pressure condition.
Soot and ash loads were high, regenerations were too frequent, boost was low and actual EGR position did not match the command.
A cracked boost pipe, loose clamps and a leaking intercooler explained the poor boost pressure.
The valve-cover gasket, oil-filter housing and turbocharger oil line were all leaking.
The vehicle felt sluggish, lacked power and struggled to maintain normal DPF parameters, with a burning-oil smell from the hot exhaust.
DPF replacement could cost $3,000–$8,000, with EGR, boost and oil-leak repairs adding thousands more.
We explained the evidence and the risk of engine damage, limp mode, poor performance, increased fuel use and fire from leaking oil. The client walked away, later found another Audi Q7 that passed with flying colours, and bought it with confidence.
Our mobile service covers all of Granville and the surrounding suburbs:
We also extend our services to the broader Cumberland Council area and Western Sydney.
The cost depends on the vehicle's complexity and exact location. Our prices start from $250 and go up to $450.
A small price compared with one DPF replacement, turbo repair or major oil leak.
When a single DPF replacement can cost thousands, an inspection is the cheapest and best insurance policy you will ever buy.
