I will start with my question and then explain why I ask it.
Question: Does the Mk5 OBDII port have a pin that is un-switched 12v power? In other words, is there a pin where the power does not go off when you turn off the key? (I thought about posting this in the OBDII scanners forum, but this is really not about scanners)
And now (as Paul Harvey used to say) - the rest of the story.
This morning I had to jump start my car. The battery was discharged (weak). There are two things new in my car. The first new thing is the battery, and the second new thing is a P3Cars Digital Interface (boost and EGT gauge). When I turn off the car the EGT gauge stays on for a few seconds and then goes off, so I know it doesn't go off immediately with the ignition. Something is apparently slowly draining my battery, and I surmise that it is one of three things:
1) My new battery is faulty
2) My P3Cars Digital Interface is slowly draining my battery
3) Something else is slowly draining my battery (a new problem)
I currently have a charger on my battery. My plan is to start unplugging the P3Cars device when I am not driving (it just plugs into the OBDII port) and see how the battery holds a charge. I am just curious if it is possible for a device plugged into the OBDII port can actually drain the battery when the car is turned off.
TIA
