This is the new shape 2007 onward, little short of data...
Recovered to us as a non runner. Actually it would start and die after a couple of seconds.
Sykes goes in on Bosch EDC16C39 CF4 but warns ISO codes do not match.
Retrieved code 0090, fuel pressure regulator not responding. Live data backed this up, on starting pressure rapidly exceeded target. 1800 bar highest at idle before system shut down.
Checked wiring to ECU thoroughly, OK.
Fitted new pressure reg, all good.

Since repair at approximatly 500 mile intervals engine will gradually loose power and stop within a few seconds(drivers description). Cycling key will allow it run normally again for a similar distance. Code 0089 sets. Sometimes it will self clear, others it gets here first.
Have removed washed & refitted regulator to no avail.

Normally I would just get another one, this is not easy as they are on extended back order. The first replacment came from a distant dealer who happened to have one in stock.

Does anyone have an accurate description for 0089? As this is a different code and problem from the first failure I suspect the regulator but need reliable info to condem it.
