AFAIK its a very well known issue and JLR know all about it. IIRC they issued a technical bulletin to sales staff to advise them which models are effected and that those models should only be sold to owners that will drive them regularly at speed on long journeys. It was revealed in some motoring mag maybe autocar or auto express.
Basically its due to poor placement of the dpf, too far down the exhaust stream, such that it takes too long to heat up or in many cases fails to heat adequately at all. A basic design error..
Some googling reveals the extent of the problem, which models are effected etc. No solution is possible apparently. During warranty JLR I believe are often changing oil FOC when the problem occurs as the engine oil becomes so diluted with diesel in failed attempts at a regen.
Out of warranty you are on your own, not only DPF problem but engine lubrication is compromised and oil level can rise excessively leading to major problems.
Lots of problems that wont/cant go way await present and future school run examples.
