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

The D4-generation A8L is a two-tonne luxury saloon that left the factory floating on adaptive air struts, and when those bags start to weep at ten or twelve years old the dealer quote tends to start a conversation owners would rather not have. The XYZ Racing Street Advanced coilover for the A8L 4WD is the pragmatic answer: a coil-spring conversion that retires the air system entirely, with the electronic damping cancellation kit included so the dashboard stops complaining the moment you turn the key.

This is the long-wheelbase, all-wheel-drive A8L specifically – a car that carries its mass high over the rear axle and rewards a damper that can actually control body movement without turning the cabin into a hard-riding compromise. Street Advanced is the right tier for that brief, because the 720-way damping range gives you enough headroom to settle the ride at speed without losing the long-travel compliance the chassis was built around.

What this coilover does for your 2010-2017 Audi A8L

Swap the failed air struts for the Street Advanced kit and the first thing you notice is that the car sits where you tell it to sit, not where the compressor decides. Ride height is set mechanically, the corners stay level on the drive, and the morning ritual of waiting for the rear to inflate disappears. Body control improves noticeably because a properly valved damper holds the nose flatter under braking than a tired air strut ever could – useful in a car this heavy.

The 720 damping positions matter on a platform like this. Soft enough at the lower clicks to keep the A8L’s long-distance manners intact, firmer through the middle of the range when you actually want to drive it, and the cancellation kit ensures the original electronic damping control unit reads the system as nominal so no fault codes throw on the dash. It is the cleanest way to delete the air system without inheriting a permanent warning light.

About the Street Advanced coilover

Street Advanced is XYZ’s road-focused coilover, developed over years by the XYZ team and refined through testing in races worldwide before being detuned for the everyday brief. It is built around 720 damping positions on a single adjuster, so compression and rebound move together across one usable range rather than splitting the tuning effort across multiple dials. That suits a luxury saloon owner who wants the option to firm the car up for a sweeping A-road but is not chasing trackside dialling-in between sessions.

Construction is the same monotube architecture XYZ runs across its road and circuit range, with a height-adjustable lower mount so corner heights can be set without compressing the springs. Coil rates are matched to the A8L’s mass and to the kerb height most owners actually want – lower than the air ride’s standard setting, but not so aggressive that it ruins the car for the M25 commute. The cancellation kit is supplied in the box; nothing extra needs sourcing to clear the electronic damping fault from the cluster.

Fitment for the Audi A8L (2010-2017)

This kit fits the long-wheelbase 4WD A8L (chassis AU49-C) from 2010 through to 2017, and is specified for the OE-air-strut variant only. The electronic damping cancellation harness is included in the kit, which is what allows clean removal of the original adaptive system on this generation.
