I like the sound of this a lot, could you email me some photo's please?
I've got to sell my D2 yet unless you were interested in a swap + cash, I was looking for £8.5k ONO for mine, let me know if you need any more details.
Cheers.
Had the same thing with my D2 a few months back, I ended up changing the lock/latch unit, I went for a genuine new part as didn't want to risk using a second hand one that could fail at any time, more details of how I did it here - http://www.greenlandrover.org.uk/new-front-door-latch/

Have you checked that the turbo wastegate is 'free' and not sticking closed? Also I've heard of similar symptoms when crankshaft position sensor is duff.

Hi Matt
I bought it from Safari-Equip back in 2009, it seems a well made bit of kit, I paid around £125 for it as a 'cash' deal at the Peterborough show.
