I had a 2.7 S Type. The DPF warning light came on, so off I went for a motorway run. Halfway up a hill (after about 15 mins of normal running), the engine gave up the ghost entirely and would only run on 3 cylinders for the (extremely slow) return trip. Upon getting a mechanic to look at it, I was told that the DPF was so badly blocked that the pressure had built up so much that it had 'blown back' into the engine and basically lunched it. I later discovered that the DPF was faulty when I bought the car, but instead of having it properly fixed, the seller had loosened the manifold slightly to relieve the pressure. Eventually, even that wasn't enough, and boom!
