Just to reboot this thread.
Had the fuel filter problem about 6 months ago, cured and the car ran well for the intervening, no problems starting, then on the French motorways this month I suffered the EML come on when full power was used in top 2 gears, with limp mode engaging.
Diagnostic gave P1065, no other codes. The car would start easily except the first time after it had been stopped when the EML had come on and we were in limp mode.
Walked though the linked Civic infotest with some telephone help from local fuel injection specialists.
Gave them the common rail part number as a check. They said this fault is now very common and they keep the part in stock. Collected the part and fitted it.
The biggest problem is getting the 17mm bolt undone.

Part was roughly £108 + VAT. Installed and running, checked, no problem so original fault code cleared.
Car is an early 2008 reg.
