Hey guys, I found a code today it's:

18010 - Power Supply (B+) Terminal 30 Low Voltage

Does this mean my battery is going or is this related to the underdrive crank pulley I installed last weekend? Has anyone had experience with this? Any input would be greatly appreciated...TIA.

Did you disconnect your battery when you changed your crank pulley. Almost guaranteed that's the problem if you did.

Hmmm...I didn't know I was supposed to disconnect the battery when changing the crank pulley. :???: The pulley doesn't have any electrial connections, though. Can you tell me anything more?

Has anyone else remedied this code?

Thanks.

I got this code after I added some monster ground wires last weekend, and I did disconnect my battery when I did it.

Clear it with my VAGCOM and the code doesn't come up anymore.

Just one of those general mechanical practices: whenever you work on the engine, disconnect the battery :lol:. What's your voltage at while the car is running?
