Speed bleeder for C4 diff locks?
I borrowed a PDT999 from a fellow Rennlister to bleed the diff locks on my C4. Unfortunately the PDT999 couldn’t connect to the PDAS so I had to bleed them the old way i.e. manually switch the system on and off while opening and closing the bleed valves. It worked ok if someone was there to do the switching while I opened and closed the valves.
A possible solution to this is to fit Russell Bleed Valves to the locks. That way it’s a one person operation. You open the valves, then switch the switch on and off until enough has been bled.
The only hitch is ordering the correct valves. Does anyone know the spec of the OE bleed valves?

Ironically I bought speed bleed valves for the brakes then realised there is no point installing them as I use a motive bleeder.

M6 speed bleeders are the size for the locks.
I use the stainless ones since i use my car rain, snow and sun...but the speed bleeders are a good idea regardless of stainless or the zinc plated standard ones

A temp fix, if you've got the bits, is a length of plastic tube with a non-return valve. I always use this together with a power bleeder (just in case) and the valve weight helps to keep the tube in position for the waste.
