Default V70 2.4D Fault codes ECM-2501/2502

This V70 logs these fault codes when accelrated reasonablt hard and puts it into limp mode.
Fault code ECM-2501 Fuel pressure to high
Fault code ECM-2502 Fuel pressure to high

We have changed the fuel pressure regulator solenoid in the pump but still no cure. We changed the fuel filter and checked all the fuel lines etc. Tempted to change the pressure sensor on the fuel rail but just wondered if anyone had come accross this fault before

Hi Thanks for the reply.
I haven't checked for a blockage in the return. I'll check it out and post back with the outcome. Is this common to block up?

Checked the return, gently blew down the lines with air line, all ok.
Doesn't appear to be suffering from excessive leak back at the injectors, not alot of fuel coming from return on injectors.

Possible source
The car has been driven until the tank is empty
Air in the fuel
Blockage in the fuel return line
Damaged fuel pressure sensor
Damaged fuel pressure control valve.

Fault symptom[s]
Noise from the engine, especially at idle
The engine jerks
The engine feels sluggish
Limited engine speed.

i think only sensor option left...

Default Volvo S60 D5 (05) Cuts out when hot.

Hi All, Please help.

I have D5 motor that randomly starting with a red triangle on dash (ENGINE SYSTEM SERVICE URGENT) and then dies. I spent the money and bought VIDA and DiCE and ran diagnostics, I get Fuel Pressure Sensor - Signal too high and if i monitor it, when cold it runs around 350bar at idle, When hot it starts jumping from 0 to 1800bar and then the engine just dies.

I checked diesel filter and had to the cranking for a while to get the air out the system. I cannot understand why its only when its hot. Thermostat says 90 Degrees but the car never reaches 90 according to VIDA, gets to 85 fan kicks in and then goes down.

Im at a loss and dont really have deep pockets. any ideas?

PoppaSmurff, you would be more likely to get a reply if you post your request for help as a new thread in the section you used (i.e. S80 '98-'06 / S60 '00-'09 / V70 & XC70 '00-'07 General) under the heading - the thread you used is over 8 years old.

The new thread button is at the bottom left of the list of threads on the page at https://www.volvoforums.org.uk/forumdisplay.php?f=19


Hope you get some help.
