[V8] 2002 A6 Quattro V8 4.2L. Starting problem

[toml99 at todomundo.com]

My friend's 2000 A6 3.0? had the ECU in a depression under the  
passenger floormats which with the plugged unnoticeable drain under  
the battery, leaked badly into the car when raining(PNW), and when I  
pulled the ECU out, it was 1/2 underwater.....Used ECU and unplugging  
all those drains under the raintray solved the problem.  Stupid place  
to put it.as it was the lowest point in the cab (think bilge pump if  
you are a boat person).    Not sure where the 4.2 is...., but could  
be there.  This is the V8 list, and mine's never got wet...Ha...Tom
