General question + noise -> in the trunk

[Maarten730]

Guten tag Allen,

Mein Deutsch reicht nicht um dass nächste "problem" zu erzahlen....

When I push the throttle...there is some noise coming "out of my trunk"
How can I describe it...like "rattling" from the fuel pump (I think this is underneath the black lid next to right of my spare tire).

Anybody an idea how to fix this problem?

Another question:

In the trunk...just rear the backseats...there is almost the entire width of the trunk... of a compartement covering with thick foam".
At this moment I am putting noise absorption plates in the car.(for my Sub)..do the holes in this compartement (about 8) have any use ?
Or should it not be a problem to cover these holes with the noise absorption plates ?

Hope to hear from you...as always...
Maarten.

Hallo Maarten

Check your complete Drive Shaft, especially the Bearing Nr. 1 + 2 in this
Picture.

The space in the trunk is for the control module for soft close, so if no soft close installed, the space is free, the other spaces were considered for a gimmick which never made it to the E32. = doors softclose.

So you can use that space, no problem.

Is the sound coming from the trunk? Then maybe yor fuel pump makes the noise, or it is not fixed inside the tank and floats around. Remove the cover in the trunk and check the correct position of the fule tank pump.

Thanks Erich and Peter

Erich...do you have by any chance picture of how the fuel pump should look like ?
I am really not familiar with these things

MfG.,
Maarten.

Hallo Maarten,

Als je de geluiden alleen onder het rijden, bij optrekken , hoort zit het probleem in de cardan as. Hier zijn drie dingen die je moet nakijken. Eerst de kruiskoppeling. Zit daar speling in ben je aan een dure nieuwe toe. Maar meestal is de oorzaak een versleten middenlager en gelijklooplager. Het gelijklooplager zit tussen de cardanas en het differentieel. om alles te vernieuwen moet de uitlaat vanaf het spruitstuk worden verwijderd.

Habe hier mal das mittenlager und gleichlaufgelenk problem auf hollandisch erklart

Hi Maarten,

for your fuel pump check this Link....  Reinigung des Tankwertgebers beim E32

It is just clipped in, you have to "Squeeze" two little Plastic things, that lie opposite to each other in the mounting frame of the fuel pump, then you can take it out.

You have to remove the fuel level sender.

It should be enough to push onto the pump to take it back again into the right position hearing a click.

There is a cable clip/binder for beeing secure that the pump stays in the mounting frame. Maybe the binder got lost and the pump is out.
