Audi Q8

The coupé-bodied flagship SUV on MLB Evo, sharing its platform with the Q7, Touareg, Cayenne and Bentayga — five vehicles, one architecture, so information from any of them applies to its chassis, air suspension and four-wheel-drive system. A 48-volt mild hybrid is standard, and on the SQ8 diesel it drives an electric compressor that spools before the exhaust turbochargers, so a boost-response complaint there involves a component the petrol cars do not have at all.

Information, not instruction

CarGeek is a reference, not a service manual. Its pages are written from public sources and from what other people have found, never from a manufacturer's own service information, so they can be wrong or incomplete for your particular vehicle. Some of what they describe carries real risk: high voltage, fuel under pressure, stored energy, hot and moving parts.

Have anything you intend to act on checked by a trained person against the manufacturer's own procedure for your vehicle. Nothing here replaces that procedure.

Nothing posted about this yet. Whatever you found is worth writing down — even a dead end saves someone the same afternoon.

What makes one worth reading:

The car — make, model, year and engine. The same fault behaves differently on each.
What you measured, not only what you replaced.
What actually fixed it — or that nothing did, which is worth knowing too.
