Following some rodent activity, I'm looking to depin a connector in my engine bay, in order to reinstall some heat sleeving.

Specifically, it's the GPF pressure sensor wire (part of the main harness) situated right next to the downpipe. The part number is 4F0973703 - it looks to be used most commonly as a PDC sensor connector, among other things.

The wiring is unaffected, as they have only gone for the heat sleeve (unlike the upstream O2 sensor, which will need replacing). I could use foil tape, however I've decided to do a proper job and replace the sleeving.

I'm looking for some information on how to depin the connector. I've ordered a set of tools, however I'm not sure if the connector is a 'micro timer' style, or an 'MQS' style. All of the videos online have featured larger connectors, requiring the use of a dual-pronged tool - which is inserted into the front of the connector to depress the pin tangs/barbs/prongs. My connector, however, only has a hole for one prong, and also has part of the pin exposed on the top.

I've ordered a used, wired plug from eBay in order to have a play with, but would appreciate any guidance anyone may have to offer :)

First Violett then Pin

I use a set of small jewellers screwdrivers to unlock the latches on each pin.

Then you hadn't had many types of plugs yet.

I beg to differ, having worked on VAG vehicles for 25+ years and many other makes for 50+ years.

And Always jewellers screwdrivers was enough?

Yes, never needed to use anything else.

Airbag? I have own Tools and need them

Thank you @Cairus and @PetrolDave

From what I've seen, the depinning tools can technically be replaced with jewellers screwdrivers, or a DIY bit of wire - having the two-pronged tool does make it a lot easier, but AFAIK there's nothing stopping you from doing one barb/prong at a time with a screwdriver, or even using two screwdrivers at once. I've got a set of Wera precision screwdrivers and the smallest, at 0.6mm, is probably better than some dedicated depinners.

Yes, with patience.

Does anyone know how to open up the 'coil pack wiring harness conduit'? I've attached a picture. I see the clips on the sides that should release, but I just can't get it to play ball. I don't need to open it, but would mean more space for me to work.
