Owned since new - 120000miles.

I didn't use it for a few days over Xmas. Tried to start it. It wouldn't. Dashboard lights bright - but absolutely dead as if there were no battery. Called recovery out. Mean while had tried agin a bit later. Car started but wouldn't run properly. Battery check OK. Alternator checked OK. Drove 100 miles. it died on me on the M4. Hard shoulder. Zilch again and then a few minutes later ok and did another 70 miles without problem. Following day same again. replaced battery just in case.

Engine also now running smoothly but then not at 100% and on it went.

Checked in a local garage. Diagnostic showed nothing. Of course the non starting problem never occurred when I wanted it to.

Over the next couple of weeks the car was back and fore into the garage. The guys blanked off the EGR valve and fitted a new crank sensor. The Injectors were tested. 2&3 leaking but not replaced.

The starting problem had gone away after the ECR was done, but smooth running hadn't. Most of the time it's flying but then I can tell that it's not running at optimum.

Just as I was rebuilding confidence that I could drive again without losing power i'm right back to square one. The car just dies on me. A few minutes later all is ok.
