I have difficulties of finding fuel pump relay on my car. Car details:
BMW 530xd E60 2008-05 Diesel 170kw.
I have found fuel pump control unit, which is in the trunk's right side, the same side where battery is. On the same side there are a lot of fuses and other sticks, but non of them seems to be fuel pump relay. Does anyone know the location of it in this type of car?
The pump is working as it should be, it has been tested in BMW center. Problem is, when I turn the ignition on, the check engine light doesn't come up for about 4 minutes 30 seconds and in that time I am unable to start the car. (it's only happening in cold whether, when it's about +2 to -5...n), when the engine is warm, this light comes up instantly when I turn the ignition on. I can hear a sound of something working while I am waiting for this light to come up, once it comes up, I can hear the sound more clearly. Once I've start the engine, this light goes off as expected. But the problem is this 4 mins delay after turning the ignition. I've read a lot about this problem and it all leads to the fuel pump relay.
