Apex Performance Tuning is an independent European vehicle specialist workshop in Wantirna South. We are not a manufacturer and not an authorised dealership.
Independent BMW inspection before you buy — private sale, dealer yard or interstate purchase. On the hoist, scanned on BMW ISTA, borescoped where it matters, road tested under load, and reported in writing the same business day with photos. E46, E9x, F2x, F3x, F8x, G2x, G8x, X-series and M models all covered from our Wantirna South workshop. We are an independent BMW specialist, not a dealership.
For service, repair and diagnostic enquiries at Apex, Wantirna South.
Apex Performance Tuning carries out independent BMW pre-purchase inspections at Unit 4/6 Woodbine Court, Wantirna South VIC 3152. We are an independent BMW specialist workshop, not a dealership, and we have no interest in whether the sale goes ahead.
Each inspection includes an on-hoist mechanical inspection, a full module scan on BMW ISTA, borescope inspection where the engine warrants it, a road test under load, and a photographed written report emailed the same business day.
The inspection is quoted in writing against the specific vehicle before booking. Open Monday to Friday 8:30am–5:30pm — 0483 939 216. Vehicle pickup and drop-off may be available by prior arrangement, subject to location and availability.
Manufacturer-spec intervals, dealer-level diagnostics and OEM-grade parts. Every service is quoted in writing against your VIN before work begins, with a clear, line-itemised breakdown.
Rod bearing wear is a known S65 weakness. We check service evidence, oil condition and sump findings, and tell you whether ACL bearings are due before you buy — not after.
High-pressure fuel pump behaviour, injector index, charge pipe condition, oil filter housing gasket and electric water pump age — all read in live data, not guessed.
The S55 in M2 Competition, F80 M3 and F82 M4 does not need rod bearings. Charge pipe, expansion tank cracking and cooling condition are the real checks.
Cam correlation values read on ISTA, cold-start behaviour observed, chain noise assessed under load on the road test.
We borescope the intake ports on N54, N55, N20, B58, S55 and S58 so you know whether a walnut blast is part of your first-year ownership cost.
ISTA shows module-level service records and mileage stamps on stored faults. When the seller's story and the car's own data disagree, you find out before signing.
Straightforward package pricing, confirmed in writing against the vehicle when you book. No surprises on the day.
$250
The fast, honest check before you commit — ideal for everyday European daily drivers where you want a specialist's eyes on the car before money changes hands.
$450
The full picture, documented. The one to book for performance cars, higher-kilometre buys and anything you'd negotiate hard on.
Extras depend on the engine and how deep the inspection needs to go — tell us the make, model and year and we'll quote the exact combination in writing before anything is booked.
E46, E9x, F2x, F3x, F8x, G2x, G8x, X-series and M models are routine work here, so the inspection targets this platform's known weak points instead of a generic checklist.
Manufacturer-level software, every module read, faults mileage-stamped. A generic OBD reader shows a fraction of this.
We are not selling the car and have no relationship with the seller. The report says what is there.
Findings photographed on the hoist and in the ports, so you can negotiate with evidence rather than opinion.
Private sales move quickly. Drop-off in the morning, written report the same business day.
The same tooling and the same standard of work, with everything approved in writing first.
Every finding photographed on the hoist. Extras approved in writing before we touch anything.
A quick 'check-over' at the roadside is not a pre-purchase inspection. A proper PPI takes 60–90 minutes on the hoist, involves dealer-level diagnostic scanning, and produces a written, photographed report you can actually use. It's not a courtesy check — it's evidence.
The car goes on the hoist. Underbody, chassis, suspension, drivetrain, exhaust, cooling system, oil leaks, transmission pan, differential — everything you can't see from a driveway walkaround. We photograph anything of note.
The car goes on the diagnostic tester — ISTA, ODIS, Xentry or PIWIS depending on brand. Every module gets read. Stored faults, pending faults, cleared-code history where the tool exposes it. On some platforms we can also see service history from the module (odometer at last service, what was actually reset), which sometimes contradicts what the seller claims.
Then the road test — cold-start behaviour, gearshift quality across the range, cruise, braking, alignment, noise and vibration under load. Not a two-minute drive around the block. A real road test that stresses the drivetrain the way a real owner will.
Finally the report. Emailed same business day. Plain-English, photographed, honest. Written so you can hand it directly to the seller if you want to negotiate — evidenced findings, not vague opinion.
European cars have known, model-specific weak points that a general PPI misses. We know what to look at, model by model — because we service these cars every day. Some examples:
HPFP condition, walnut-blast history, oil filter housing gasket, electric water pump age, charge pipe condition.
Expansion tank cracks, charge pipe (S55), rod-bearing evidence on high-km S55 M2 Comp/M3/M4.
Timing chain tensioner condition, water pump, DSG fluid history, walnut-blast history.
Chain guide inspection, cam-follower wear, carbon buildup on high-km cars.
Cam-lobe wear inspection, head-bolt corrosion evidence.
IMS bearing type and evidence of wear, rear main seal, AOS condition.
Fluid service history, clutch adaptation values on ODIS, temperature history.
Service history vs claimed km, fluids interval compliance, brake fluid age.
Yes — M cars are core business here. We check the platform-specific items that matter (S65 rod bearings on E9x M3, S55 charge pipe and expansion tank, S58 cooling), read every module on ISTA, and road test under load.
Substantially. A general check looks at tyres, brakes and obvious leaks. A BMW inspection reads BMW-specific fault memory on ISTA and checks the failure points that actually cost money on each chassis.
Yes, and most agree. If a seller refuses an independent inspection, that is useful information in itself. Vehicle pickup and drop-off may be available by prior arrangement, subject to location and availability.
A written report with photographed findings, the full fault-memory read, road-test observations, and a plain recommendation on whether to proceed, negotiate or walk away. Each inspection is quoted in writing against the specific vehicle beforehand.
We inspect any vehicle that can be brought to our Wantirna South workshop. For cars outside Victoria we can tell you exactly what to ask for, and inspect it on arrival before you commit to further spend.
Wantirna South, VIC 3152. Easy from EastLink, M1 and Melbourne's east. Call 0483 939 216 to book.
Send your registration or VIN, current kilometres and what the car needs. We come back with the scope in writing — usually within the business day — and nothing extra is carried out without your approval.
