I'm unsure if this will help, but when my D5 kept going into limp home mode, and it was cured after I switched off the engine and restarted, I *think* that it was the turbo vanes needing a push - by this I mean stick it in 4th, get to 40mph, and floor it. Do this a couple of times. I haven't had a limp home mode since.
