V12 valve-train and injector faults
Misfires and ticking on a twelve-cylinder engine need per-cylinder diagnosis, not guesswork. We use live data and compression testing before replacing anything.

Every model has its own weak points. These are the ones we see most often in Dubai conditions — and how we deal with them.

Manifold cracks and loose heat shields show up as tick or rattle. Inspected cold, replaced with updated parts when confirmed.
A 789-hp V12 is hard on gearbox fluid. We service at the correct interval and run adaptations.
Virtual Short Wheelbase system faults and body-module gremlins diagnosed with the factory tool.
Radiators, fans and oil coolers checked and cleaned — dust and sand block them.
Carbon-ceramic measurement, pads and the right tyre for 789 hp in heat.

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.

WhatsApp is fastest. Or leave your number and we will call you back.
The Ferrari 812 Superfast is the last of a line — a front-mounted, naturally aspirated V12 with no turbos and no electric assistance. Owners of the Superfast, the open-top 812 GTS and the 812 Competizione want a workshop that respects the engine and knows its habits. Hallmark Auto Services has serviced Ferrari V12s from the 599 and F12 to the 812, and we bring that experience to every job.
Annual or 10,000 km. An 812 service includes engine oil and filter (the correct grade and quantity matters on this engine), full inspection, software check, brake and tyre report and a road test. Coolant, brake fluid, DCT fluid and spark plugs follow the multi-year schedule.
Written estimates, genuine parts, photographs of what we find and a six-month warranty. If you are searching for a Ferrari 812 garage in Dubai, message us on WhatsApp to book.
Slightly — more oil, more plugs, more coils. But the 812's engine is not turbocharged, so there is no charge-air system to maintain. Kept on schedule, an 812 is a very robust car.
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 812 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.
