What the known faults on this Audi A5 typically cost to put right at a UK independent garage · use the figures to price risk before you bid, and to justify a reduction when something shows up on inspection.
The single priciest documented job on the 2016–2024 Audi A5 is timing chain, tensioner & guides at £900–£2,400. Few cars need every repair listed here · treat £2,410–£10,150 as the full exposure if one arrived with all of them.
Timing chain tensioner wear causing a metallic rattle on 3.0 TDI V6 models.
Inspect · Ensure the engine is completely cold. Open the bonnet, start the car, and listen near the bulkhead for a sharp metallic rattle lasting 2-3 seconds before oil pressure builds.
DPF and AdBlue faults on 2.0 TDI models
Inspect · Check for warnings after a full-temperature run
S tronic and multitronic hesitation and juddering
Inspect · Test low-speed manoeuvres and check gearbox service records
MMI infotainment and camera faults
Inspect · Test every screen function and the reversing camera
Front control arm bush wear causing knocks and wander

Daytime Running Light (DRL) LED modules burning out, causing the light guide to turn yellow or fail completely.
Inspect · Switch the ignition on and activate the DRLs. Stand in front of the car and check that the LED strips are bright white. Any yellowing indicates a burnt-out light tube requiring a costly replacement.
Frameless door window regulator failure or microswitch faults causing the glass to catch on the roof seal.
Inspect · Open and close each door from the outside. Verify the window glass drops instantly by a few millimetres when pulling the handle and raises tightly into the seal when closed.
Coolant leak from the thermostat housing and water pump module on 2.0 TFSI (EA888) engines.
Inspect · Shine a torch under the intake manifold on the left side of the engine block. Look for dried pink or purple crust, indicating a weeping housing seal.
