Different push buttons are used depending on the gear knob. This has to do with all the different types of gear knobs that are supplied for the trim models.
Because Volvo does not supply these parts separately, it is almost impossible to find out which push button is on which gear knob.
The only way to determine which one you need is to compare the old part with the two repair kits. The part number of the other kit is RD30756903A. (see recommended products)
The rear view of the part is most easy to compare.
