The 2001 Audi S4 Avant stands out as a rare Santorin Blue wagon with major performance upgrades and strong recent care. This no-reserve example mixes factory rarity with enthusiast-focused hardware.

Santorin Blue Styling with Subtle RS4 Cues
The S4 Avant shows refreshed lower bodywork, aluminum mirrors, and roof rails. RS4-style grilles, Euro xenon headlights, and smoked lenses add a focused look.

Suspension and Braking Setup
H&R coilovers and upgraded stabilizer bars sharpen road feel. AP Racing front calipers with slotted rotors pair with fresh Michelin Pilot Sport 4 S tires.
Cabin Condition and Equipment
The interior features Onyx Silk Nappa leather, carbon trim, and heated front sport seats. A Kenwood and JL audio setup works with an Alpine touchscreen and wired smartphone support.

Noted Interior Wear
The rear bench upholstery is damaged, the seat heater works partially, and the left-rear window regulator is broken. Minor electronics issues are also noted.
Engine and Performance Highlights
The twin-turbo 2.7L V6 carries BorgWarner K04 turbos, Wagner intercoolers, and a 034Motorsport intake. Supporting mods include Bosch 550cc injectors, an APR bi-pipe, and a single-mass flywheel.

A Motoza tune delivered 412 hp and 413 lb-ft at the wheels on a SuperFlow dyno, giving this Avant notable gains over stock output.
Recent Mechanical Work
Recent service includes a radiator, coolant components, heater core, CV boots, and an exhaust gasket. The timing belt and water pump were replaced earlier in the current ownership period.

Transmission and Drivetrain
The six-speed manual was rebuilt and fitted with a B7 RS4 clutch and a JHM stabilizer bracket. A high-bias Torsen differential improves traction but chatters in tight turns. A rear differential mount was added recently.
Included Extras and Records
The sale includes winter wheels, spare headlights, and records documenting the significant 2014 upgrade work performed by 034Motorsport.

Summary
This 2001 Audi S4 Avant combines factory rarity with comprehensive performance upgrades and documented maintenance. Offered at no reserve, it provides a well-sorted and engaging take on the classic B5 platform.
