I recently noticed the check engine light was lit in my car. So I
bought an engine scanner to see what the problem was (I thought it was
the MAF). But the scanner read: 18010.
In the the manual, that came with engine scanner ( I don't have my
car's owner manual), the definition given for this code was: Power
supply (B+) Terminal 30 - Low voltage. But that doesn't tell me much.
Could anybody out there, please let me know what this means.
After scanning the engine, I erased/reset the problem code and the
check engine light is now off, even after a good ride.

Also, my car is a 99 A4 2.8

Thanks any thoughts would be great!!

I'd like to fix this myself if possible.

The code 18010 has the following possible causes :

a) Weak battery
b) Alternator fault
c) Cables disconnected from battery.

Have you disconnected the battery recently ? I'd personally ignore the
problem unless the 'Check engine light' reappears. Then check the cables to
the battery, the battery itself and then the alternator.

Yes I did, recently unplug my battery and I remember it being a little
loose when I replugged it. But lazy me, I didn't re-tighten the wire
until I saw the check engine light come on. ( I must have hit a bump
and the wire must have moved slightly). I had a hunch that it could of
been that. Well thanks alot.

No problem. I hope it's solved.
