- Engine / equipment
- 2.7 and 3.0 TDI V6 (EA896 and EA897): Audi A4, A5, A6, A7, A8, Q5, Q7; VW Touareg, Phaeton and Amarok; Porsche Cayenne, Macan and Panamera
- Period mentioned
- 2004–2018
- Symptoms
- Chain rattle for the first seconds after a cold start; power loss or limp mode from the intake flaps; coolant or oil loss in the engine V; EGR faults with rough idle.
- Possible cause described
- The timing chains sit at the rear of the engine, against the bulkhead, and their tensioners lose pressure. The intake flaps use plastic linkage rods that wear. The coolant valve, oil cooler gasket and EGR are packed into the engine V and leak with age.
- Check for the garage
- Listen to a cold start (a rattle lasting more than 2–3 seconds is a bad sign), check flap operation with a diagnostic tool, look for leaks in the engine V and check the oil change history.
- Cost cited in the source
- Tensioners and chains: approx. €2,000–4,500; EGR with cooler: €1,000–1,500; oil cooler gasket: €300–600A rough figure from the original database, not an up-to-date quote.
