The two door handles in the Diablo suffer numerous
scratches over time due to the fact that they are made from a soft
plastic material. Fortunately replacing them is simple and not expensive
(by Lamborghini standards).

submitted the following description and photographs. There
is also a more detail description for removing a Diablo door panel
on this site at click here.
Fig 1. Remove the small screws to
expose the two bolts behind the caution light
Fig. 2. Remove the black plug
being careful not to damage the leather to expose another bolt.
Fig 3. Remove the speaker grill.
On the 6.0 you only gently pry out the black part, the polished ring
stays with the speaker. Then remove the speaker to expose yet another
bolt.
Fig 1. Lastly remove the three
forward panel screws to get to the last bolt. The panel lifts off and
upward. I tied mine to the door frame using a piece of wire so as to not
damage it.
Fig 4.
Two 10MM bolts hold the
handle in. Just remove and push upward from the inside (not outward)
When replacing, be sure to use some silicone to stick the washers to the
new handle. I also had to trim off a small foam gasket from the old
handle as the new ones did not have it. To replace just reverse all steps.
