High-voltage battery and charging
Charging faults and HV warnings diagnosed with the factory tool and correct high-voltage procedures.

Every model has its own weak points. These are the ones we see most often in Dubai conditions — and how we deal with them.
Charging faults and HV warnings diagnosed with the factory tool and correct high-voltage procedures.
Reduced-power or missing eDrive is usually software or a 12 V issue before it is hardware.
Multiple circuits, all inspected for leaks and flow. A hot battery limits performance.
Correct fluid, correct procedure, adaptations.
A weak 12 V battery is the number-one cause of strange hybrid faults. We test it first.
Brake-by-wire calibration, carbon-ceramic measurement, correct tyres.
At Hallmark Auto Services we work on the Ferrari 296 GTB / GTS every week. We know its service schedule, its parts references and the faults it develops in Dubai’s heat, and we diagnose before we quote. Independent, transparent and specialised — dealer-level tools without dealer pricing.
Every job starts with a written estimate, uses genuine parts, is photographed as we go, and is covered by a six-month warranty.
Tell us what the car is doing — or just that it is due — and we will come back to you within working hours with a plan and an estimate.
Collection and delivery within Dubai is available on request.
WhatsApp is fastest. Or leave your number and we will call you back.
The Ferrari 296 GTB and 296 GTS pair a 120-degree twin-turbo V6 with an electric motor and a high-voltage battery. Like the SF90, they need a workshop with hybrid training, high-voltage safety equipment and the current diagnostic platform. Hallmark Auto Services services and repairs the 296 in Dubai with all three.
Annual or 10,000 km. A 296 service includes engine oil and filter, inspection of every cooling circuit, HV and 12 V system check, software and module check, brake-by-wire and tyre report, and a road test in hybrid and eDrive modes.
Written estimates, genuine parts, correct high-voltage procedures, a six-month warranty. Message us on WhatsApp to book your 296 GTB or GTS.
We keep the HV battery at the correct state of charge during service and use the factory tool for any HV diagnostics. You do not need to bring anything other than the car and your charging cable if you want it checked.
Ferrari's schedule is annual or every 10,000 km, whichever comes first. In Dubai heat we recommend not stretching it: oil, coolant and brake fluid age faster at 45°C, and a 296 that sits in traffic on SZR works harder than the schedule assumes.
Yes. Wear items, filters and fluids are genuine Ferrari or the OEM supplier's part; we tell you which and show you the invoice.
Servicing to the factory schedule with genuine parts and a full record does not void a manufacturer warranty, and a complete history from a known specialist is what buyers and pre-purchase inspectors look for.
A standard annual service is usually same-day. Diagnostics take a few hours; larger repairs get a written estimate and timeline before any work starts.
