I think both the 3.0 and 4.2 have DPFs.. They can be coded out as part of a map process.

The issue is people buy diesels and just do the school run in them, so the engine never reaches operating temperature for long, which is what's needed for the DPF cycle to work. Hence why over the last 6-7 years, there's been regular stories of people having to pay for new DPFs when they're not running the car long enough.

30-40 miles every other weekend should be enough as keep it clean. But it needs to really be motorway miles at a decent speed to allow car to warm up and DPF clean process to kick in
