I have difficulties of finding fuel pump relay on my car. Car details:

BMW 530xd

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.

What symptoms are leading you to the fuel pump relay? Can you hear the pump run for a few seconds after turning the ignition on? Several forums also recommend making sure you have at least 1/4 tank of fuel as E60 pumps show early signs of failure when fuel is low but not empty. I have tested fuel pumps by hitting the tank with a rubber hammer. If it starts it is generally the pump. –  mikes Dec 9 '13 at 2:58
I've edited my question, please have a look. –  Paulius Matulionis Dec 9 '13 at 8:23
The fuel pump relay is on the fascia fuse box, behind the glove box. It is the corner most relay of the two. –  Allan Osborne Dec 9 '13 at 11:21
Thanks @Allan, I didn't realize that there is another fuse box, thought the only one is located in the trunk. –  Paulius Matulionis Dec 9 '13 at 13:06
