Default Vag-tool code ?'s

My engine light came on and found that i needed to replace the battery, so i did. The CEL went away but, I hooked up my Vag-tool and i came back with this Fault code:

1 DTCs FOUND
18010 - Power Supply Terminal 30: Voltage too Low
35-10---Intermittent

What does this mean and how do i fix it?

Default BTW .. The Bentley's manual has the DTC error codes linked to what to test etc .. very handy.

There is also a searchable DTC site online but I don't have the bookmark on this machine

Default Ask here or buy the Bentley's CD. Generally if you ask here you'll get a fairly quick reply. You can

also visit the Vagcom groups at Yahoo. It is searchable and many DTC's have been discussed there. http://groups.yahoo.com/group/VAG-COM<ul><li><a href="http://groups.yahoo.com/group/VAG-COM">http://groups.yahoo.com/group/VAG-COM</a</li></ul>

Default Any time you remove power to the ecu by disconnecting the battery

or taking the ecu out you will get that code. It just keeps a reading of it so the dealer can see it.
