Holden
Commodore, Colorado, Captiva, Cruze
Alloytec timing correlation, LS misfire, intake leaks, oil pressure warnings, Captiva diesel/EGR/DPF, ABS wheel-speed faults.
Known-fault bulletin tip: Alloytec P0008/P0016/P0018/P0019 direction: check oil condition, cam actuator command, cam/crank correlation and chain stretch data before quoting chains. LS misfire: prove ignition, injector pulse and compression before coils.
Ford
Falcon, Territory, Ranger, Focus
COP misfires, smart-charge faults, ZF/BTR transmission complaints, Ranger boost/DPF/EGR faults, Focus cooling and transmission warnings.
Known-fault bulletin tip: Ranger/BT-50 underboost: pressure-test charge pipes/intercooler, verify actuator command, MAP/MAF plausibility and DPF restriction before turbo replacement. Falcon/Territory no-start: check PATS, ignition switch, BEM/PCM powers and crank signal.
Toyota
Hilux, Prado, LandCruiser, Corolla, Camry, RAV4, HiAce
VVT/oil control, A/F sensor faults, EGR/DPF diesel issues, cooling faults, ABS/C1201 paired engine faults.
Known-fault bulletin tip: C1201 commonly stores with an engine ECU fault; repair the engine/DTC root cause first. VVT faults: check oil grade, OCV filter, actual cam movement and sludge before sensors.
Mazda
Mazda 2, Mazda 3, CX-3, CX-5, BT-50, Mazda 6
MAF/intake leaks, misfires with compression checks, Skyactiv cooling/VVT logic, BT-50 Ranger-related DPF/boost checks.
Known-fault bulletin tip: Cylinder-specific misfire that does not move with coil/plug/injector needs compression, leakdown and valve timing checks. BT-50 diesel underboost follows Ranger-style pressure and actuator testing.
Nissan
Navara, X-Trail, Patrol, Pulsar, Dualis
MAF contamination, boost leaks, EGR soot, cam/crank heat faults, EVAP vent contamination and CAN faults.
Known-fault bulletin tip: YD25 diesel: suction control valve/fuel-rail control concerns need commanded/actual rail pressure under load, not guesswork. Heat-soak cam/crank codes need waveform capture hot.
Mitsubishi
Triton, Pajero, Outlander, Lancer
EGR/intake carbon, turbo actuator/boost solenoid faults, DPF pressure hose faults, CVT warnings and ABS wheel-speed issues.
Known-fault bulletin tip: DPF differential pressure faults: inspect hoses for splits/soot blockage, confirm sensor zero offset KOEO and pressure rise with RPM before replacing DPF.
Hyundai / Kia
i30, Tucson, Santa Fe, Cerato, Sportage, Sorento
GDI carbon, coil/plug misfires, purge valve hard-start after refuel, A/C compressor control and charging/earth faults.
Known-fault bulletin tip: Hard-start after refuelling: command/seal-test purge valve and watch fuel trims. GDI misfire: verify plug gap, coil output, injector balance and carbon/compression.
Isuzu
D-MAX, MU-X
Boost leaks, MAP contamination, DPF differential pressure hoses, EGR soot and charging system load checks.
Known-fault bulletin tip: 4JJ1 boost/DPF complaints: clean-test MAP, pressure-test intake, inspect DPF hoses and compare commanded vs actual boost before turbo parts.
Subaru
Forester, Outback, Impreza, XV
Oil leaks/consumption, O2/catalyst faults, cooling concerns, CVT warnings and misfire/compression verification.
Known-fault bulletin tip: P0420 after oil consumption or misfire requires fixing the cause first; compare front/rear O2 activity and check exhaust leaks before catalytic converter quotes.
Volkswagen
Golf, Passat, Amarok, Tiguan
Battery/gateway faults, DSG/TCM codes, VNT boost control, intake leaks, water-pump/thermostat housing concerns.
Known-fault bulletin tip: Low-voltage and battery registration issues can trigger unrelated modules. DSG/TCM faults need transmission-specific scan data, fluid condition and power/ground checks.
BMW
3 Series, 5 Series, X models
VANOS/VVT faults, electric water pump faults, IBS/battery registration concerns, valvetronic and coolant leak diagnosis.
Known-fault bulletin tip: Electric water pump faults: command pump, verify power/ground/LIN or BSD communication, bleed function and coolant temp behaviour before pump replacement.
Mercedes-Benz
C/E-Class, Sprinter, Vito
NOx/DPF/EGR diagnostics, glow plug faults, CAN/voltage complaints, A/C compressor control and boost leaks.
Known-fault bulletin tip: Sprinter/Vito diesel faults: check AdBlue/NOx status, DPF soot load, exhaust temp sensors and boost leaks before clearing inducement-related codes.
