Aston Martin Virage Rapide Vanquish Starter Alternator

Aston Martin Virage (2011–2012), Rapide (2010–2020), and Vanquish (2012–2018) share the same “VH Generation” architecture and 6.0L V12 engine lineage. Consequently, they utilize nearly identical starting and charging hardware.

1. Starter Motor: Part No. 8G43-11000-AA / AB

The starter motor is a heavy-duty unit designed to crank the high-compression V12.

• Compatibility: This part is common across the DB9 (2008+), DBS, Virage, Rapide, and Vanquish.

• Common Issue (The “Heat Soak”): Because the starter is tucked deep within the engine “V” or near the exhaust manifolds, it is prone to heat soak.

  • Symptom: The car starts perfectly when cold but struggles or produces a single “click” when trying to restart after a long, hot drive.

• Pro-Tip: Before replacing the starter, check the Starter Motor Relay (8G43-11000-AB) in the fuse box; these often fail due to the high amperage draw.

2. Alternator: Part No. 8D33-10300-AA

The alternator for these models is a high-output 200 Amp unit (manufactured by Denso) to support the car’s extensive electronics and cooled/heated seating.

• Interchangeability:

  • Virage / Vanquish / Rapide: Use the same 8D33-10300-AA unit.

  • Early DB9 (Pre-2008): Used a lower-output 140 Amp version (4G43-10300-AC). While it may bolt on, it is not recommended for the newer cars as it cannot keep up with the electrical load of the newer B&O audio systems and modules.

• Failure Symptoms: * “Battery Not Charging” or “Electrical System Fault” warnings.

  • Burning smell from the engine bay (often the internal rectifier diodes failing).

  • Flickering interior lights or erratic behavior of the paddle shifters (Touchtronic).

Important Maintenance Note: The Battery Connection

Aston Martins of this era are extremely sensitive to voltage. A weak battery will often mimic a failing starter or alternator.

• Voltage Test: With the engine off, the battery should read 12.6V+.

• Charging Test: With the engine running, the alternator should be pushing 13.8V to 14.4V to the battery. If it is below 13V, the alternator is failing.

• Jump Starting Warning: Never use a high-voltage “boost pack” on these cars. The electronics are fragile; always use a stable 12V jump source or, better yet, a slow trickle charge to 100%.
