I had an 07 plate 2.0l TDCI which is the engine built in conjunction with Peugeot.....
Seriously the most problematic car I've ever owned, and had a proper "gremlin" which made it randomly drop in to limp mode; not too much of an issue solo as i could get to a safe point, turn off and re start and all would be fine for a days, weeks or months sometimes. It came to a head when it kept doing it with the caravan on the back, and D-day came when all was well going to Cornwall then it was dropping in to limp mode every few miles on the A30. Never got to the bottom of the issue as each time the OBD was scanned, it gave a different fault.
On the plus side, it was a nice car to drive, got good MPG and had a huge luggage space (and payload), almost van-like with the flat fold seats. I would probably have another one just for that reason but i'd be doing my homework and not get an early model.
On the towing side of things, I had a S1 Valencia on the back (1565kg MTPLW) and it was capable, slightly struggled on bigger hills but was a very stable tow car.
