Har nå kjørt et par år med defekt/dårlig fødepume på tds'n. Symptomer var tungstarted på varmmoter, ble etterhvert det på kaldmotor også. Motoren kutta når det ble under ca 20 liter på tanken.
Tok ulveskinnet på meg i dag og fikk bytta den. Noen anbefaler å tømme tanken for diesel, tok sjansen med ca 30 liter på tanken, det gikk fint.
Pumpa ligger på høyreside under baksetet.
Fulgte denne DIY'n:
1. First of all, you may want to disconnect your battery. This will prevent any un-wanted problems (I did not actually disconnect battery, I just removed the fuel pump fuse. But I was just being lazy).
2. Remove rear bottom seat by pulling straight up. It may feel impossible to remove, but you will have to use some brut strength in order to pop them off the seat off its holder.
3. Locate the location of the fuel pump on top of the “rear” seat on passenger side. It looks like a round black padded cushion with wires going into it. Lift the padded cushion. You will have to disconnect the wires and the hose going into the top of the location of where the fuel pump is.
4. The top part is being held by a large round screw type ring. You will have to remove that ring. I used a flat head screw driver and a hammer to remove it. Place the screw driver on one of the ridges and hit the large ring counter clockwise to loosen.
5. Once loosened and removed, be sure to carfully lift the plate off. The fuel leveler is located right under that plate and if you pull it out with too much force, you can snap it. Again, this is not that difficult and I may be scaring you a little. But, I just want you to be careful. Lift the plate straight up. Y ou will need to cut the zip ties off the hose going to the pump(your new OEM pump should come with this) and ONE metal clamp that is attached to the pump (your new OEM pump should have ONE new clamp). There are 2 metal clamps on that hose. One on the hose that is attached to the pump and one that is attached to the plate. Cut the ONE clamp,that is attached to the plate, off. (If you are wondering what the clamp looks like, go to your power steering resorvoir and look beneath it. That is exactly how they look. That’s only if you have an OEM clamp on your car.)
6. Reach in with your hand and locate the 2 LARGE plastic clamps that are holding the fuel pump (If your tank is full of gas, get ready to get your hands “wet”. My suggestion is NOT to use gloves, just use bare hands. Rubber gloves will tear). The large plastic clamps are located on the side of the fuel pump and when you squeeze them, the pump will lift out. I would recommend you to view your “NEW” pump because the plastic clamps on their (on OEM bmw pumps that is).
7. When you lift up the fuel pump, there are 2 wires at the top. Remember which wires are which (i.e. brown is negative…etc). Remove the female plug wires. Cut the last of the zip ties off the fuel hose.
8. Replace the fuel pump in reverse order with all necessary zip ties and the one metal clamp. Replace the fuel pump in its “home”. Make sure to feel that the little “nubby” hits the little hole down in the “home”. If you look straight down into the home of the fuel pump, you will notice a hole about the size of a penny. Look at your new fuel pump and you will see which way your fuel pump should go.
9. Replace the ring gasket include with your new OEM fuel pump.
10. Replace everything in reverse order.
