So last night I was changing the tie rod on my 2.7 and I though oh I can flash my tune while in changing the tie rod.

So I go grab my computer which has a terrible battery life. I plug the charger in and hook the compter up and I get the tune flashing.

I reach in to start adjusting my tie rod and felt a shock on my left hand. I figured I just pinched a nerve or got stabbed by a piece of steel or something. So I reached it again. This time on my other arm I touched the fender and got shocked.

So I went and grabbed my continuity tester and found that somehow the whole car was charged with a.c. power. And I mean the whole car. Any where with bare metal would electrocute you.

Now I'm assuming it is an issue with my laptop but I am not sure. The tune flashed fine and car runs great.
 
Just posted this to see what people think.
And to warn them you're car could be trying to kill you.

No it was on all 4.

Tried two different chargers and they both make the car hot?

Switched mode PSU ties -ve against the AC side. Sounds like a poor PSU. There is a filtering cap between the two sides. It's normal to feel a slight "nibble" if on any low impedance body part (sweaty hand/finger) due to capacitive coupling, but not a shock. Sounds like yours is leaking or isn't grounded properly.

But for both to have failed?

Happens the same yesterday with an A3 2002 with M3.8.3 in dynamometer...
