4E0907553E 4E0910553E 5SG00840701 Audi A8 S8 D3 4E Modul Control Suspensie – Original Uzat & Testat

Descriere

Acesta este un modul de control original al suspensiei pneumatice – referențiat sub numerele OEM 4E0907553E, 4E0910553E și 5SG00840701 – montat pe Audi A8 and S8 of the D3 generation, the 4E-platform flagship produced from 2002 to 2010. The D3 A8 and S8 replaced conventional coil springs with an electronically managed air suspension system, and this module is the operational centre of that system, controlling ride height and damping characteristics in real time across all driving conditions.

The module manages the air compressor unit, inlet and outlet solenoid valves, level sensors at all four corners, and the high-pressure reservoir to maintain correct ride height under varying passenger loads and speeds. At motorway speeds the system lowers the body to reduce drag; at low speed it raises the car for ground clearance. On S8 variants and Adaptive Air Suspension-equipped A8s, this module also switches between comfort and sport damping profiles based on drive mode selection, delivering the D3’s ability to feel simultaneously cosseting and composed.

Symptoms that typically point to this module failing on the D3 A8 or S8 include one or more corners sagging overnight or during standstill, the air compressor running continuously without reaching target pressure, fault codes for level sensor plausibility errors even after the sensors have been verified, ride height warnings on the instrument cluster, or the suspension defaulting to a fixed height and losing its automatic levelling function entirely.

This is a genuine used OEM module sourced from an Audi A8 or S8 D3 4E and tested for core suspension control functionality before despatch. As a used air suspension control unit, coding or adaptation to the receiving vehicle may be required using VCDS or Audi-level diagnostic equipment. Verify all OEM numbers against your existing module before purchasing.
