Uptown Motor Works is one of the few independent workshops in Melbourne's west with a qualified BMW/MINI High Voltage technician on the floor. From battery diagnostics to drivetrain repair, every job is carried out to dealer-level safety standards.
Every high voltage job is isolated, tested, and signed off using the same safety procedure used in BMW dealership workshops — de-energised, verified, then worked on.
Cell-level health checks, isolation fault tracing, insulation resistance testing, and state-of-health reporting using BMW's ISTA diagnostic platform.
Service and repair of ASM, PSM, and SSM electric motor types across BMW's Gen 5 and Gen 6.0 EV platforms, including dual-motor xDrive configurations.
Inverter, onboard charger, and DC-DC converter diagnostics for BMW's latest 800V architecture, plus charging port and connector fault repair.
Battery module inspection, coolant loop service for liquid-cooled packs, contactor replacement, and pack removal/refitting for major repairs.
Post-repair recalibration of energy management and recuperation systems, software updates, and fault memory clearing via BMW Triage tooling.
Scheduled servicing for BMW and MINI electric and plug-in hybrid models — brake fluid, coolant, cabin filters, and 12V auxiliary battery checks.
The high voltage system is fully de-energised and locked out before any panel is removed, in line with manufacturer safety procedure.
Full fault code read and live data analysis using BMW ISTA and Triage to pinpoint the exact source of the issue.
Targeted repair to motor, battery pack, inverter, or charging components, using genuine or OE-equivalent BMW/MINI parts.
Systems are recalibrated, fault memory cleared, and the vehicle re-tested under load before being signed off as safe to drive.
BMW and MINI EV systems operate at voltages that can be lethal if handled incorrectly. We don't recommend attempting any HV battery, motor, or charging system work without certified training and the correct PPE and isolation equipment. If you're experiencing an HV fault warning, drive cautiously to your nearest specialist or arrange a tow rather than continuing to operate the vehicle.
Yes. We can carry out independent diagnostic work and many repairs without affecting your existing manufacturer warranty, in line with Australian Consumer Law. We'll always advise you if a particular repair is best handled through a dealership claim.
These refer to BMW's different electric motor designs — Asynchronous (ASM), Permanent magnet Synchronous (PSM), and Separately excited Synchronous (SSM) motors — each used across different BMW EV platforms and axle positions. We diagnose and service all three types.
Yes. A full ISTA diagnostic scan will identify whether the fault is isolation-related, a battery cell imbalance, a motor fault, or a software issue, and we'll walk you through the findings before any repair work begins.
Where the pack design allows it, we can replace individual faulty modules rather than the entire pack, which is significantly more cost-effective. We'll confirm what's possible for your specific model after diagnostics.
It depends on the fault, but as a general rule we recommend minimising driving and booking a diagnostic scan as soon as possible. Some HV faults can cause the vehicle to enter reduced power mode without warning.
Speak with our high voltage technician about your EV or hybrid's symptoms, and we'll get you booked in for diagnostics.
