[solid]

Fine buy with one known weak point

Worth buying, but only on the right car. Only with verified timing chain/tensioner replacement history or budget reserved for immediate preventative replacement (€800-€1,500).

Verdict

The chain is most of the story here, and stretch with worn guides is very common.

Get someone to listen for a whine or rattle on a cold start and to look at the chain and guides, because that is the job most likely to cost you. Injectors fail occasionally and cheaply, so treat them as a watch item and not a dealbreaker. Price the chain inspection into the offer and this is a reasonable car.

This report combines 66 owner posts, forum threads and official records. An issue only makes the list once the evidence is strong enough, an official recall on its own or several independent owner reports, and the score weighs how often each problem happens against how bad it is when it does.
