Audi A8L 4WD (OE FOR AIR STRUT) (Cancellation Kit for Electronic Damping) 2010-2017 — Coilovers

The D4-generation A8L left the factory on adaptive air suspension, and a decade on those air struts are the chassis’s most expensive liability – sagging overnight on a cold start, throwing damping faults, and quoting four figures a corner to replace like-for-like. This XYZ Racing coilover kit for the Audi A8L 4WD (2010-2017) is the cancellation route: it swaps the OEM air struts for conventional coilovers and includes the electronic damping cancellation so the cluster stays dark.

Built specifically for the AU49-C long-wheelbase quattro, it trades the self-levelling air setup for a fixed ride height you set yourself and damping you can actually service. For owners keeping a heavy D4 limousine on the road past warranty, it turns a recurring repair bill into a one-time upgrade.

What this coilover kit does for your 2010-2017 Audi A8L

The first thing you notice is the end of air-suspension anxiety: no more morning sag, no more limp-home warning on a frosty start. With the air struts gone, the A8L sits at a fixed height you set with the threaded bodies, so you can bring the long-wheelbase stance closer to the arch or keep it sensible for speed bumps and motorway miles. Damping is adjustable mechanically rather than electronically managed, which lets you firm up a car that weighs the best part of two tonnes and tighten its body control through quick direction changes. Because the kit cancels the electronic damping circuit, the instrument panel reads clean – no suspension fault lurking on every MOT. For a quattro saloon this size, the result is a flatter, more planted car without the air system hanging over your running costs.

About the XYZ Racing coilover range

XYZ Racing build this A8L kit as a full air-to-coilover conversion rather than a ride-height bolt-on, which is why the electronic damping cancellation is integral rather than an afterthought. The range covers nine specs for this chassis – Street Advanced and Super Sport at the road-biased end, Top Sport and Circuit Master for track work, Racing Spec and Pro Rally for competition, plus Tarmac Rally, Gravel Rally and Drift Spec for specific disciplines. The road and circuit specs use height-adjustable threaded bodies with damping adjustment, so static ride height and corner balance are set independently of spring preload. Moving up the range brings firmer valving and stiffer rates aimed at sustained load rather than supple cruising. Whichever spec you pick, the core job is identical: delete the failure-prone air system and the electronic damping it depends on, and replace both with mechanical parts you can rebuild.

Fitment for the Audi A8L (2010-2017)

This kit is cut for the AU49-C A8L 4WD – the long-wheelbase, quattro D4 built 2010 to 2017, specifically cars that left the factory on air struts with electronic damping. It is the cancellation version, so it suits owners replacing a failed or failing OEM air setup rather than supplementing one. Confirm your car carries the adaptive air suspension before ordering.
