Bmw 2000 323I..code p1250. - BMW Cars & Trucks

Code P1250 = Pressure Regulator Control Solenoid Circuit
This is the fuel pressure regulator. I would recommend you get a Good mechanic to deal with this. Fuel injection systems run at Very High pressures and can be dangerous if you don't know what you are doing.

1250 is the fuel pressure regulator and 1569 is variable timing control solenoid. Both will cause rough running. I would check the regulator out first.

OBD code of: "P1250- PRC Solenoid Circuit Malfunction. Which malfunction of Fuel Pressure Regulator Control unit. PRC is located
by the fuel pump by the left side on the bottom rail under some plastic you will find it. PRC costs about $90.

P0304 = #4 cylinder misfires
P0170 = Fuel Trim, Bank-1
P0173 = Fuel Trim, Bank-2
P1250 = this is invalid code for BMW
P1188 = Fuel control, bank-1, sensor-1 (pre-cat sensor)
P1189 = Fuel control, bank-2, sensor-1 (pre-cat sensor)
Vacuum leaks and/or sensor defective for the issues of the codes.
This error codes really need parts to replace. But you have to replace the thermostat first. Then clear the codes and see if any reappears,then replace defective part/s

P1250- PRC Solenoid Circuit Malfunction, could be a problem with you fuel pressure regulator, i would check the pressure of the fuel rail with a fuel pressure gauge depending on what BMW you own fuel pressure spec it different.E39s are supposed to have 50 +/-2 psi of operating pressure

James,

Based on the numerous codes and others who have experienced many of these problems, I would say you have a vacuum leak near the intake. I would also clean my DISA and ICV as well.

Please buy a Peake code reader (No..I don't sell them but I can vouch that they save time and money in the long run. A generic code reader will have you throwing thousands of dollars into repairing your car that aren't needed.). The Peake code reader is BMW specific and gives a more detailed result because the reader scans BMW specific codes that a generic OBD 2 reader can't.

This guy has an excellent video on how to clean your ICV and I think he has one on the DISA (which is next to the ICV):

Hope this helps!

los tres codigos hacen referencia a malfuncion en control de combustible , pero si aparecen los tres a la vez es muy probable debido a filtro de gasolina sucio

P1250 is a faulty fuel level sender. Does your fuel gauge act funny?

p1188: Fuel Control (Bank 1 Sensor 1)
p1189: Fuel Control (Bank 2 Sensor 1)
p0171 and p0173: These are very common codes on BMW's which can also be false codes, try clearing the codes and run the test again they may not come up again.
p1250: Never came across that....

Hi if the catalyst was replaced or eliminated this code p421 will always come out p1250 is that there's a problem with the ignition switch good luck
