What does a McLaren service include?
Every McLaren service begins by identifying the car exactly: model, year, specification and the software level installed. A 12C, a 570GT and a 720S share the spirit of the marque, not their service schedule.
The car is first driven on the road, then raised on the lifting points the manufacturer specifies: the carbon tub and very low underside call for suitable pads and a gentle ramp. Everything we find is set out in an itemised estimate, and no additional work is carried out without your approval.
- Engine oil and filter, following the check procedure specific to dry-sump lubrication
- Coolant, hoses and side-mounted radiators
- SSG dual-clutch gearbox oil, according to the manufacturer’s schedule
- Brake fluid, pads and discs, iron or carbon-ceramic
- Hydraulic circuit of the suspension and of the nose-lift system, where fitted
- Spark plugs, air filters and cabin filter
- Reading of the control units, stored fault codes and software level
M838T and M840T twin-turbo V8: what to watch
Most McLaren road cars use a flat-plane-crank, dry-sump twin-turbo V8 mounted behind the cabin. The 3.8-litre M838T powers the 12C, the 650S and the 570S family; the 4.0-litre M840T replaced it in the 720S and then the 750S. Dry-sump lubrication demands a precise method for reading the oil level: a measurement taken outside the specified conditions gives a misleading figure.
On these engines the turbochargers run extremely hot. Their oil and coolant lines, the unions and the neighbouring hoses are examined at every visit, as are any signs of weeping on the casings. The radiators, fed by the side intakes, collect leaves, grit and dust: they are cleaned and checked, because poor heat exchange takes its toll first on a forced-induction engine.
The Artura marks a change of architecture: a 3.0-litre twin-turbo V6 paired with an electric motor, as a plug-in hybrid. Its high-voltage system is only ever approached with the procedures and equipment the manufacturer prescribes; the workshop will tell you precisely what it can take on for your car.
SSG dual-clutch gearbox: what should be checked?
The Seamless Shift Gearbox, or SSG, is the seven-speed dual-clutch transmission of the 12C, the 650S, the 570S family and the 720S. Housed inside the casing, the clutches cannot be inspected by eye: their condition has to be read. The diagnostic tool gives access to wear and adaptation values, and allows the learning procedures to be run again after any work or software update.
Those values are always cross-checked on the road. Juddering when pulling away, hesitant shifts when cold or a warning on the instrument panel will direct the inspection. Gearbox oil is renewed according to the manufacturer’s schedule. The logic is similar to that of the dual-clutch gearboxes described under Ferrari servicing, but each marque has its own procedures, and here it is McLaren’s that apply.
ProActive Chassis Control: a hydraulic circuit to keep an eye on
On the 12C, 650S, 720S and 750S, the dampers are linked by a hydraulic circuit that controls body roll in place of conventional anti-roll bars. That circuit ages: accumulators, hoses, unions and sensors must be checked methodically.
A leak, a car that no longer holds its ride height or a suspension fault message calls for a precise diagnosis: the tool reads the faults and available values, while a visual inspection locates any traces. The 570S family and the GT use a more conventional layout, with anti-roll bars and adaptive dampers, so the checks differ. The nose-lift system fitted to many McLarens protects the front bumper on ramps and speed humps; its circuit is checked in the same way as the suspension.
Carbon-ceramic brakes, tyres and bodywork
Carbon-ceramic brakes are fitted, as standard or as an option, to a large part of the McLaren range. They are inspected using the manufacturer’s method: condition of the surfaces and edges, prescribed measurement, specific pads. A carbon-ceramic disc lasts a long time on the road, but it does not tolerate knocks when the wheels come off, so each wheel is removed using a centring guide. The checks are described in detail on our brakes page.
Tyres approved by the manufacturer carry a specific marking on the sidewall; on a car that covers few miles, their age matters as much as their tread depth. The composite or aluminium body panels and any exposed carbon parts are inspected during the service: a chip, a crack in the lacquer or an impact on the front bumper is dealt with before it spreads.
Warranty, service history and low-mileage McLarens
European law allows a car to be serviced outside the manufacturer’s network without losing its warranty, provided the service schedule is followed with parts of equivalent quality. If your McLaren is covered by a manufacturer’s extended warranty, its terms are reviewed with you before any work begins. The invoice details every operation and every part, with its origin: it forms the service history that matters so much to a McLaren’s value.
Many McLarens cover very few miles. The control units draw on the battery even with the ignition off, so a battery conditioner and proper seasonal preparation prevent many electrical faults on restarting. Other mid-engined supercars have their own particular needs, set out under Lamborghini servicing. The workshop’s general approach is explained on the servicing and maintenance page, and the marque’s families on the McLaren page.
