Which crimp tool is suitable for crimping MQS pins? These are the ones that go in almost all the modules - FRM, FZD, TCU, MULF. These pins lock into the housings/connectors.

I tried using an astro pneumatics 9477 crimp tool, but the rolls on the wires are not coming out.

Think BMW has some special tool to do crimping.
i just strip the wires, place them on the MQS pins, fold the parts where the MQS pins grip the wire insulation and use a plier to tighten them. it does help to add a bit of solder to the exposed wire to secure it to the MQS pin.

Thanks snoozee. After wasting 5 or so pins, I think I'm getting good at using the astro 9477 crimp tool, what do you think of this:

I originally tried the same crimp tool (astro pneumatics 9477) that I bought from Amazon and returned it because it didn't seem to work good at all for the MQS pins.

I ended up buying an open barrel terminal crimper tool from ebay which worked great.

This is the one I bought. (Although it was 5 bucks cheaper when I bought it from the same company last summer.)

Thanks so much Triger716!! I've asked many electronics shops, no one seems to know...
