Hi all,

recently changed the nitrogen canister on my r32 and installed a doluck dtmiii,
Now when I go to bleed the system when I unplug then bleed switch under the dash it doesn’t seem to work as before, It used to make a noise as soon as it was unplugged and connecting the switch on and off for the air gap doesn’t do anything, before as soon as you cracked the nipple open the pump would start working, now it just seems random, 
no warning lights or ecu fault codes.
I’ve tried with the OE G sensor too and still the same issue, 

Any ideas ?

I assume everything was apart above the subframe to change the accumulator, so connector not reseated properly or damaged wiring sounds like a possibility.

The pump should also run when the car is if the pressure is low, so start the engine then open the bleeder and see if it starts bleeding that way. That will isolate bleed switch/wiring issues.

Is there enough oil in the reservoir cause it will turn off if there isn’t
