Car Forum / Audi Cars / August 2006Trouble code 18010 Power supply (B+) Terminal 30 - Low voltage
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. > I recently noticed the check engine light was lit in my car.

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. Richard 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. > > I recently noticed the check engine light was lit in my car.
