3.0L S55 Twin-Turbo - GTS (Track focused) version
Petrol
Check this by inspecting the cooling system: Look for any signs of residue around the charge-air cooler as the S55 engine relies heavily on its intercooler system; any moisture or coolant loss might suggest a future service requirement.
While driving at low speeds with the steering wheel turned, listen for any 'clunking' from the front end; the GTS uses specific suspension components that are high-performance and may eventually show signs of wear in the bushings.
Check this by operating the DCT gearbox in manual mode: Ensure the gear shifts are crisp and responsive without hesitation, as the twin-clutch transmission is robust but benefits from consistent, documented oil changes.
While inspecting the engine bay, observe the oil filler cap and dipstick area for any signs of milky residue, as proper crankcase ventilation is vital for the longevity of the S55 twin-turbo setup.
Usually marks the point where brake pad and rotor wear might become a discussion, especially if the vehicle has seen track use.
A common window to perform a comprehensive 'major' service, including spark plugs and transmission fluid health checks.
Consider having the suspension geometry checked and bushings inspected to ensure the GTS handling stays sharp and precise.
Prioritise regular engine oil changes every 10,000km or annually using high-quality synthetic lubricants.
Keep a close watch on the brake fluid levels and change intervals, especially if you plan to enjoy some spirited driving.
Ensure the engine air filters are clean, as the S55 breathes heavily and clean intake tracks keep the turbos happy.
Regularly inspect the tyre condition and pressures, as the GTS setup is quite specific regarding grip and road feedback.
Maintain the coolant system health to ensure the intercoolers and radiators function at their peak efficiency.
Estimated repair costs if issues arise
While the GTS is often equipped with advanced braking tech, if this component needs attention in the future, the estimated cost in NZ is higher than standard steel setups due to the complexity of the material.
Depending on the car's history and whether it has been tuned, you might eventually need to budget for a preventative crank hub fix to ensure the timing components remain secure.
Because the GTS is track-focused, it's common to consider a suspension refresh as the car ages to maintain that factory-fresh handling feel.
