ATTEMPTING TO START THE FLOODED ASTON MARTIN DBX THAT I BOUGHT MY DAD

The video follows a YouTuber who recently bought a flood-damaged Aston Martin DBX for his father and is documenting the first serious attempt to get the ultra-luxury SUV running. It opens with a walk-around that highlights the extent of the water intrusion: silt in the wheel wells, corrosion on exposed metal, and a musty odor inside the cabin. The host explains the auction history, purchase price, and the gamble involved in reviving a modern Aston loaded with complex electronics that may have been submerged for hours.

Before turning the key, the team begins a meticulous inspection. They pull the interior carpets, revealing standing water hidden beneath the floorboards, and remove the seats to access multiple control modules. Each module is unplugged, dried, and treated with contact cleaner. The engine bay receives equal attention; spark plugs come out, cylinders are fogged with lubricant, and the turbochargers are spun by hand to check for binding. A fresh battery is installed, all fuses are verified, and the on-board diagnostics are scanned, returning a long list of communication errors typical of flood vehicles.

With preliminary safeguards in place, the moment of truth arrives. The host sits in the driver’s seat, foot on the brake, and presses the start button. The DBX’s starter motor cranks confidently but the twin-turbo V8 refuses to fire, leading to immediate troubleshooting. Fuel pressure is measured at the rail and found to be zero, pointing to a likely shorted fuel-pump control module. Swapping in a used unit from a donor DB11 restores pressure; a second crank produces a sputter and brief idle before the engine shuts down with an immobilizer fault.

Determined not to end on a defeat, the crew isolates the immobilizer, reprograms a spare key, and attempts one final start. This time the engine roars to life, running rough but holding idle while clouds of moisture burn off from the exhaust. The video closes with a list of next steps—flushing all fluids multiple times, replacing soaked wiring harnesses, and ordering new carpets—yet the host is visibly ecstatic. The flooded Aston Martin DBX, once written off by insurers, has taken its first breath again, inching closer to becoming the dream gift for his dad.
