Audi Q5

Material defect on camshafts of EA897 engines (272 hp and 218 hp) built 2014 to early 2017. A broken camshaft causes total engine failure. Audi performed goodwill repairs where service history was complete.

Symptoms: Loud ticking or knocking from the engine bay clearly exceeding diesel combustion noise; often occurs on cold start or under load

The 3.0 TDI V6 uses four timing chains. From around 160,000 km cold-start rattling occurs. Timing chain replacement requires extensive engine removal and costs €1,500–4,500.

Symptoms: Cold-start rattle that disappears as the engine warms up; engine check light; rough running

The variable oil pump in the EA897evo reduces oil pressure at low rpm for Euro 6 optimisation. With fuel-diluted oil viscosity drops, which can lead to seizure damage.

Symptoms: Rising oil level (fuel in oil), oil pump clatter, abrupt engine damage possible without warning

Short trips prevent complete DPF regeneration. The filter clogs and the engine automatically reduces power. Frequent active regeneration promotes fuel ingress into the oil.

Symptoms: Power loss and increased fuel consumption, DPF warning light, oil level rises from fuel ingress

On the CRTE the coolant control valve and oil cooler can become leaky and cause gradual coolant loss. Left untreated, overheating damage is likely. The intake manifold can become contaminated with oil mist.

Symptoms: Dropping coolant level without visible leak, coolant smell in engine bay, temperature rising under high load

On 3.0 TDI models (03–12/2012) oil mist can damage the brake booster diaphragm, significantly reducing braking performance. Recall required.

On Q5 models from 2011 the panoramic roof glass can spontaneously shatter in severe frost (below -20°C) and send fragments into the interior.

From about six years of age, control arms and coil springs show elevated wear that is flagged at MOT. Heavy bodywork and all-wheel drive accelerate bush wear.

The S-Tronic dual-clutch gearbox tends to harsh judder on pull-away and delayed response, especially in urban traffic. Clutch wear from 80,000 km possible.

Bei Fahrzeugen mit über 150.000 km zeigen Antriebswellen erhöhten Verschleiß. Besonders Gelenkwellen-Manschetten reißen und führen zu Fettaustritt und Lagerschaden.
