TD6 L322, 2003, 107,000 miles - Every morning when I leave my house I get as far as around 6 miles and the fuel injection system error comes on and the engine cuts out while I'm doing around 50mph. I leave it for a few minutes and it's difficult to start again, takes 3 or 4 tries but then off it goes like there's no problem, the error disappears and it's fine for the rest of the day. I had a fuel pump fitted last week and no other errors were showing on the garage computer but it's still got this issue. I'm having no other problems, it starts fine first thing. It's going back into the independent LR garage next Monday and they're going to keep it for a couple of days and try and catch the issue while it's hooked up to the computer. Any ideas what it could be?
