5.9L V12 (AM11) - Final MY13+ Series
Petrol
While accelerating in a lower gear, listen for any hesitation or 'hunting' in the idle, which can be an early indicator of coil pack or spark plug degradation in the AM11 engine.
Check this by engaging the transmission between Park, Reverse, and Drive while stationary; the ZF 6-speed auto should engage smoothly without any noticeable shunt or delay.
While driving, steer firmly onto a slightly uneven road surface to listen for any knocking or clicking from the front suspension, which may suggest that the control arm bushings or anti-roll bar drop links are due for a refresh.
Before turning off the engine, operate all windows and the door handle release mechanism to ensure the 'drop-glass' function cycles correctly, as the microswitches in the door modules can occasionally become temperamental in our climate.
Usually marks the point where the initial suspension bushes may start to show signs of perishing.
A common interval for a comprehensive fluid flush, including the differential oil and coolant system rejuvenation.
The period where ignition coils and secondary oxygen sensors often benefit from a proactive inspection or replacement.
Keep a consistent log of the engine oil levels; these V12s appreciate being checked every few fuel stops.
Ensure the trickle charger is used if the car sits for more than a week, as the DB9's electronics are sensitive to voltage drops.
Prioritise an annual inspection with a specialist who understands the specific nuances of the AM11 engine architecture.
Keep the cabin air filtration system clean to prevent any musty odours during the humid New Zealand winters.
Periodically cycle the infotainment system and retractable navigation screen to keep the mechanical gears and internal contacts moving freely.
Estimated repair costs if issues arise
Although these late-model DB9s feature the robust ZF automatic, if your example has had spirited use, you might eventually need to budget for a transmission service or torque converter inspection to ensure long-term shifting health.
Depending on the car's history, the rubber bushings and damper components may eventually show age-related wear. It is wise to set aside funds for a refreshed handling package to maintain that signature Aston Martin ride quality.
If this component needs attention in the future, the estimated cost in NZ reflects the labour-intensive nature of accessing the V12's architecture; it is often most cost-effective to address these as a complete set.
