Aston Martin Vantage Control Panel KY6318C612BA
part number KY63-18C612-BA identifies the HVAC Control Switch Pack (often called the Climate Control Panel) for the second-generation Aston Martin Vantage (2018–2024).
This unit is the primary interface on the center console that houses the rotary dials and buttons for the air conditioning, fan speed, and seat heating/ventilation.
1. Finish & Configuration (The Suffix Matters)
The suffix -BA indicates a specific aesthetic and functional configuration. In the 2018+ Vantage, there are two primary visual “packs” for the interior switchgear:
-
Dark Rotaries (-BA / -BB): The -BA version features the “Dark Chrome” or black knurled rotary dials. This is typically found on cars with the “Jewellery Pack” in Satin or Dark finish.
-
Silver Rotaries (-AA / -AB): The standard silver or bright chrome rotary finish.
-
Seat Functions: The switch pack also differs based on whether your car has Heated only or Heated & Ventilated seats. The -BA suffix is generally the high-spec version supporting both functions for the “Dark” interior theme.
2. Integration with Mercedes-Benz Tech
Because the 2018–2024 Vantage uses a Mercedes-AMG sourced electrical architecture, this control panel communicates directly with the Mercedes-based COMAND infotainment system.
-
Plug & Play: If you are replacing a faulty unit with the exact same part number, it is usually a straightforward physical swap.
-
Software: However, if the car does not recognize the new unit (e.g., seat heaters won’t activate), a “Soft Reset” or a coding handshake via the Aston Martin Diagnostic System (AMDS) may be required to pair the new hardware to the car’s VIN.
3. Pricing & Availability (2026 Estimates)
This is a high-value electronic component. Because the buttons are tactile and prone to wear or liquid damage (from spilled drinks in the cupholder), demand for used units is high.
| Condition | Estimated Price | Note |
| New OEM (Dealer) | $3,600 – $4,200 (£2,900 + VAT) | Often a special-order part from Gaydon. |
| Used (Excellent) | $850 – $1,200 | Check for “sticky buttons” or peeling finish on the rotary knurling. |
| Refurbished | $1,400 – $1,800 | Cleaned and tested with a warranty. |
Common Failure: The “Sticky Button” Syndrome
A common issue with the KY63 series panels is that over time, the soft-touch coating on the buttons can become “gummy” or sticky, especially in warmer climates.

Pro-Tip: If your control panel works perfectly but just looks worn, there are specialist interior restorers who can laser-etch new icons onto your existing buttons for a fraction of the cost of a new $4,000 unit.
