The DPF has failed on my car for the second time. What can I do?

Just over a year ago, I wrote to you to flag a DPF issue with my 30k mileage 2015 Land Rover Discovery Sport. After a massive fight, Land Rover replaced the entire DPF system for free (even though out of warranty). Now, just 10k miles and 12 months later, the entire DPF system has failed again. LR refused any support and I have a £2300 bill. Given the 20-page "D8 Dilution Explained" document that's freely circulating - which highlights systemic design issues that almost guarantee such failures, what are your thoughts on LR's responsibilities/legal obligations? In 2015, diesel was just becoming a bogey issue from a tax/environmental perspective, but these issues suggest the real problem - that no one warned buyers about the DPFs.

Unfortunately, it's out of warranty and I suspect Land Rover will blame any issues on driving style. 30k miles over five years isn't many for any diesel car. We normally only recommend diesels to drivers covering more than 12k a year (mainly motorway miles) to prevent DPF issues. You'd be relying on a goodwill gesture from Land Rover and, as they've already replaced the DPF system once, that's unlikely. We'd recommend replacing your Discovery Sport with a petrol or hybrid vehicle.

Should I buy a diesel SUV? I drive about 7,000 - 8,000 miles a year, much of it short journeys in town.
We have the opportunity to buy Vauxhall Insignia with a diesel engine. It has 41,000 miles and it's selling for £4150, but we're worried about the DPF. Your opinion would be appreciated. Many thanks.
I'm a bit of a novice and don't know much about DPFs and diesel engines (or...well... cars in general). Normal small family car use, so mostly shop trips, longer 20min+ drives at weekends and a few longer...
