2020 ASTON MARTIN DBS SUPERLEGGERA

Typical onset: 15,000-40,000 mi

Symptoms: Transmission overheating warnings on track or spirited mountain drives, Burnt ATF smell after hard use, Limp mode activation with transmission temp faults, Fluid contamination visible in reservoir

Fix: Replace transmission oil cooler and flush/refill ATF. Requires partial undertray removal and cooler line disconnect. 4-6 hours labor. Many shops recommend upgraded aftermarket cooler for track-driven cars.

Estimated cost: $2,800-4,200

Typical onset: 30,000-60,000 mi

Symptoms: Cold-start piston slap or knock lasting 10-30 seconds, Oil consumption exceeding 1 quart per 1,000 miles, Low-end knock under load with clean fuel, Metal flakes visible in oil filter during analysis

Fix: This twin-turbo V12 runs aggressive tune and tight tolerances. Bearing issues require crank removal; piston ring wear means short-block work. Engine-out labor is 20-30 hours. OEM parts availability can delay jobs 4-6 weeks. Some engines show premature wear from inadequate warm-up routines or track abuse without proper cool-down.

Estimated cost: $28,000-55,000

Symptoms: Stumble or hesitation under wide-open throttle above 5,000 RPM, Intermittent check engine light with lean fuel trims, Hard starting after sitting for extended periods, Fuel pressure drop under high demand

Fix: High-pressure fuel system sensitive to contamination. Requires fuel filter replacement and sometimes fuel pump module service. Tank drop or rear seat removal depending on filter location. 2-4 hours labor. Recommend fuel system cleaning and fresh premium fuel if car sat unused.

Estimated cost: $800-1,600

Typical onset: 20,000-50,000 mi

Symptoms: Clunk when shifting from Park to Drive or Reverse, Excessive driveline vibration at idle in gear, Transmission gear whine transmitted into cabin, Visible tearing or separation of rubber mount material

Fix: The ZF 8-speed mounts absorb significant torque from the V12. Replace transmission mounts (typically rear mount fails first). Requires transmission support and subframe access. 3-5 hours labor.

Estimated cost: $1,200-2,400

Typical onset: 25,000-55,000 mi

Symptoms: Boost control fault codes (P0234, P0299), Overboost or underboost conditions, Audible fluttering or chattering from turbo area under load, Reduced power with check engine light

Fix: Carbon buildup or actuator arm wear causes wastegate binding. Sometimes cleanable, often requires actuator replacement or turbo R&R for access. Each bank is 6-9 hours labor due to tight packaging in the V-configuration.

Estimated cost: $3,500-6,500

Symptoms: Touchscreen unresponsive or stuck on boot screen, Navigation system crashes mid-drive, Backup camera intermittent or black screen, Bluetooth connectivity drops randomly

Fix: Mercedes-sourced COMAND system with Aston-specific software. Often resolved with module reset or software reflash at dealer. Persistent issues may need head unit replacement. 1-3 hours diagnostic and reflash labor, 8-12 hours if head unit swap needed.

Estimated cost: $500-4,800

Symptoms: Battery dead after 5-7 days of sitting, Warning messages about multiple systems on startup after short sits, Parasitic draw testing shows 300+ milliamps with car off, HVAC blower or infotainment stays partially powered when locked

Fix: Multiple control modules can fail to enter sleep mode. Requires systematic module isolation and software updates. Sometimes gateway module replacement needed. 2-6 hours diagnostic labor depending on complexity.

Estimated cost: $600-2,200
