Removing PCM2

[DRDT]

I need to remove my PCM2 Becker unit to check something at the rear of it. Unfortunately the previous owner had removed all four of the plastic locking plugs which hold the springs in when removing the unit. I have spare plugs but cannot find a way to insert them while the PCM is in situ. Is there a special tool available or has any member any ideas on how to get the unit out? Thanks

Difficult but you need two friends and 4 flat screwdrivers.

Your friends need to press the catches in whilst you guide the PCM out by either reaching underneath or pushing from behind.

Not easy and you need small friends.

Hi
I take it that you have removed the horse shoe?
If you get a torch and shine it into the air vent above the PCM you will see two tabs push these down and you will be able to pull out the vent.
There are 4 torx srews that hold the frame into the dash board, if you remove them you will be able to pull the whole unit out.
Disconnect the cables , they have side tabs that you have to squeze to remove (the one by the side side of the fibre loop has to be removed first before you can remove the fibre loop).
You should now have the PCM removed to take to a work bench to work on.
I hope this helps, I found it the best way to remove the PCM.
Regards
Nick

I think you may be confusing PCM1 and PCM2 removal. PCM1 has the spring clips, but PCM2 has 1/4 turn plastic locks, and I think this is what David is saying is broken.

However, Nick (B) is correct that you can unscrew the complete mounting frame from the dasboard. IIRC there are 4 Torx screws.

Thank you all for the helpful advice. I had removed the horseshoe and the 4 torx screws but I could not see a way to release the vent even after looking at the parts manual; Will give it a go and post a result idc. Thanks again

I think there is a clip at the top. I'll post a diagram when I get to my PC.

Richard - thank you. I could have done with your diagram but had not checked my thread before starting he job! I eventually found the 2 clips on top of the air vent and by dint of luck managed to insert a small flat screwdriver each side to depress them enough for the vent to come out. I put a slight touch of grease on them when replacing the vent which made them clip in easier (hopefully unclip easier as well if needed in the future). Thereafter it was straightforward and with the PCM2 on the bench was able to fit the four plastic securing lugs without any problems. No way they could be fitted with the PCM in situ without tremendous patience and luck. All back together together plus a small peice of foam inside the top of the horseshoe to stop an annoying creaking as the plastics rub together on a rough road surface.
