Audi A7 Parts For Sale

Air suspension failures are among the most common and costly problems on the A7, particularly on models with the optional adaptive air suspension. Compressor wear, leaking air struts at any corner, and faulty ride-height sensors can all trigger the suspension warning light. Suppliers in our network carry compressors, individual corner struts, valve blocks, and control modules at significantly lower cost than Audi dealer parts.

Matrix LED headlight modules are another frequent concern on the 4G facelift and all 4K models. While the technology is impressive, individual LED segments can fail, and replacement assemblies from Audi can exceed £2,000 per unit. Used complete headlight assemblies from low-mileage accident-damaged vehicles are available through the network at a fraction of that cost. Always confirm the part number to ensure compatibility with your car's ADAS calibration requirements.

The supercharged 3.0 TFSI in the 4G A7 can develop timing chain stretch at higher mileages, leading to rough running and potential engine damage. The supercharger nose cone bearing is another known weak point — a whine that develops gradually before eventual failure. On the 4K, the motorised tailgate mechanism with its complex electric operation can develop faults with the struts or latch. Suppliers stock timing chain kits, supercharger components, tailgate struts, and ECU modules.
