Hi There,


I search on this forum about this issue, i don't know if it's common or not i couldn't find any answer.
I own an Astra J Hatchback 1.7 CDTI 96kw 131hp 2012 (A17DTF) with ECU ACDelco AA6P 55584315.

I got 2 main errors prompted on OPCOM and also on other diag tools.
P261A -- Low voltage on Auxiliary Water Pump Circuit (this was the first time i diagnosticated the problem on a service with a delphi tool) 
P067A -- cylinder*4 glow plug control circuit low voltage
