Is the Vauxhall 1.6 CDTi engine reliable?

I am debating getting an Astra 1.6 CDTI but have heard some horror stories regarding the chain rattle and DPF issues on this engine. Am I just seeing the few bad cases (as you will never hear about the good ones) and providing I look after my car it will be completely fine or is it a legitimate issue that I should be aware off?

My other alternative is to get a 1.4i (non turbo) Astra or 1.6 (non turbo) Astra in petrol form as these engines seem to be pretty decent on the reliability front. However, I am slightly concerned about their performance/overtaking and efficiency.

We'd be interested to know why you would discount a petrol turbo model here, as the 1.4T is by far the pick of the Astra range from 2015-21. There are a number of documented problems with the diesel engines, the timing chain being the biggest bugbear. However, a well-maintained one should be fine - just factor in that you may need a tensioner and new chain at some stage down to simple wear and tear. The 1.6 non-turbo is a pretty reliable thing and while it's no performance car, it will be fine for your needs in most driving situations.
