BMW 2.0 N47 diesel engines seem to have timing chain issues. Volkswagen and Audi 2.0 TDI has timing belts that need replacing every 60k miles or every 4 years. The Lexus IS220d is a saloon, not a coupe and the engine is a bit coarse and has had cylinder head issues. You seem to have missed off Mercedes C-Class Coupe and E-Class Coupe. The 2.1 litre Mercedes diesel engine (200CDI, 220CDI, 250CDI) is a bit long in the tooth now but is robust until the timing chain eventually stretches and powers millions of vehicles.
