Another Thought On Intermittent Start Issues

[Peter Golledge]

Steve,

Brings back memories... The infamous LT-1Q suffered from this, the battery
ground was loose and went high-resistance from time to time.  Enough current
got through to run but an attempt to crank dragged the volts down to the
point where the fuel pump/ECM would not function.  Troubleshooting without a
meter 100+ miles from home was fun.

The vibration from a soundly mounted 5.7l motors shakes _everything_ loose
eventually.  I had the sun roof motor fall out after steamboat last year.

... after sending my earlier post I remembered a similar situation on my old
'88 5kCSQ Avant.  From time to time ... usually when SWMBO was driving ...
the car would fail to crank with the ignition switch.  I beat on that one a
very long time because it was so intermittent ... usually when I got to the
car to check it out the problem was fixed.  Final cause?  The ground lug at
the battery end was loose where it bolted to the frame of the car.  I don't
know if the A4 has a battery under the back seat ... not sure it really
matters ... just be sure to check the connections at the battery to ensure
they are all appropriately snugged ...
