These are issues documented for the Audi A5 in general - things to check for, not a diagnosis of any particular car. Whether a specific car has one depends on its age, mileage, service history and how it was used.

Rough Repair Cost

Independent workshops typically charge R18 000-R32 000 for this, depending on exactly what's needed. The full independent-vs-dealer breakdown is in a full AutoLytiQs report.

What To Check

Yes, through digital diagnostics and acoustics. On Gen 3, an OBD scan of the 'Camshaft Adaptation Intake Bank 1' live data channel catches this before it becomes audible - a deviation past -4/-5 degrees means the chain needs replacement regardless of noise. Acoustically, both generations produce a loud, crisp diesel-like clicking or loose metallic clattering from the timing cover area during warm idle. If a Gen 2 tensioner has already failed completely, the engine will instantly refuse to start and crank with a completely hollow, compressionless sound - by that point it is a repair, not a warning sign.
