BMW E83 2.0D (150HP) Cold Start Issue: Shuts Off Multiple Times, Fuel Pressure & Pump Query

Hello.
BMW E83 2.0d 150HP will start and go off in the cold two or three times in the cold. Then it will start and work properly. Warm burns at touch. Interestingly, when smoking cold, turning twice three times for ignition helps. Looks like fuel reversing. The question is what pressure should the pump generate in the tank, because it gives about 0.8 Bar. Unfortunately, "ours" have already been here and I can not see the parameters or errors.

And why is that?

Someone pushed toe to DPF.

So it's best to restore the error table.

For CR, this is not enough ... There is no second (threshold) pump?

This engine has no other pump.

You have one pump in the tank, the other at the height of the driver's seat, under the floor of course (unless it was different in m47?)
And stupid question, the fuel filter when changed?

The second pump is not there. Filter by customer relationships exchanged, but to be sure, I'll look at him tomorrow. I am interested in the pressure of the pump, if it is not enough. I can't find anywhere.

No pump at the fuel filter? I check after pictures and the filterek is together with the pump
Call the service tomorrow (regenerating pump injection, etc.) give up for the customer that you want to give the car back and ask for pressure, they usually prompt because they count on the customer

At the filter it is a heater. I don't think they have info regarding this.

Then check if you stick the cake during the first cold start to the inlet, it will also go out, if it does not go off, it will be known that the problem lies in the fuel supply.

After all, I wrote that turning to ignition helps several times.

And what does that have to do with it? There is no certainty with the problem is the lack of fuel
In Bmw, the problem is often made by the glow plug driver, there may also be a problem, it's a pity that it doesn't connect to the computer, because the error would pop up right away

The driver and candles checked first.

@ sly_1978 For the CR system, I think the pre-pump pressure is 3.5 bar. 0.8 is for the VP pump, but I can be wrong, I don't do it every day . If I'm wrong, somebody correct me, but 0.8 bar is not enough for this system.

Hello. Maybe someone will find it useful to have information related to my problem in X3. (Engine 2.0d M47) -2005 r Many users of the e83 model with a diesel engine have a problem with starting the engine, for example after a night stop, when we start the cold engine in the morning, it ignites but after 2-3 seconds it goes out. this problem. In my X3 the problem was a damaged EWS 3+ module (BMW number 61 35 6 941 986) it was replaced with another newer generation EWS 4 (BMW number 61 35 9 127 086) Electronic diagnosis did not detect any error. Apparently everything was working. Additionally, two more relays were replaced. One located behind the glove box in a bright green color, responsible for controlling the fuel pump power supply. It is marked K96 / X10156 on the diagram. It has been replaced with a brand new one. (Relay No. BMW 61.36 837700) and the second relay responsible for powering the engine control unit. It is located under the hood in the engine compartment on the left side (driver's side). In the diagram it has the designation K2003a / X2085. Relay is blue. New relay number (BMW number 61.36 6 915 327) Since the EWS module and relays have been replaced, the problem has not existed. In addition, 4 glow plugs and the glow plug relay / driver have been replaced. snapping vortex flaps they have been removed from the suction manifold.

Hello, I have the same problem, can you tell me what the reason was? Thanks in advance.
