Reliability, common problems and owner reviews for the Hyundai i30 1.6 CRDi diesel (D4FB). Check this before you buy used.
The 1.6 CRDi — economical and generally solid, but the chain-driven design shows timing-chain wear between 80,000–120,000 km, signalled by a clacking noise on cold start. Plus the usual DPF on short-trip cars. Good with quality-oil discipline (the chain tensioner runs on oil pressure) and motorway use.
