Not sure which fuse it is, but it will be in your manual in the glove box. Your radio may need reset, though. Volkswagen has anti-theft radios and in some instances you will need to have them reset. Your manual in the glovebox will tell you if your radio has this feature.

Probably has an anti-theft code that needs to be entered. Check owners manual and other papers that came with it for an unlock code. You may have to go to dealer and they check your VIN# and give you the code as well.

You may need your lock code. ?????? LOL Look in your owners manual. The installer usually jots it down on a back blank page. Good Luck

This seems to be a common problem with this series of radio. If you open the drivers door and pop the fuse panel cover off the side of the dash, then locate fuse number 42 ( should be 25 amp). Remove the fuse, check to see if it is blown(it usually isn't), if it isn't blown leave it out for about 30 seconds to 1 minute and then reinstall. Hope this helps it worked on my 02 Jetta TDI.

It is the overriding by intersteller priority dimensional language conversion filtering. Nothing to worry about, It can be easily defeated and modulated by tightening your removable Radio Antenae.:-) Good Luck_Ned_

if the fuses are numbered, the radio fuse is number 42.

Ouch! you've got engine coolant in the exhaust from a leak somewhere...DO NOT run this engine until you get someone (dealer is best in this instance) to diagnose ($50-125)

Fuse number 42 is for the radio reset. Pull it out and put it back in. It's a warranty problem, expired now no doubt.
