07 Passat - Radio/Nav on, no audio... amp?
Hy folks,
I searched for this and didn't find a thread that had a resolution, so here I am.
07 Passat wagon with Sat/Nav/Changer(in glove box) that the head unit works fine. All volumes are up and none of the sources have audio. It's totally stock and never been opened up and had extras added. It turns on and off ok, changes soures... blah blah blah...
Yesterday the audio just went away. No warning, just gone. I've looked at the fuse for the radio... it's fine.
I can't find where the fuse for the amp under the drivers seat is. It's not in the book and nobody has posted it here that I could find.
My thoughts:
-Find that (those) fuses and change them
-Check ground to amp
-beg for help here.
I've seen posts that suggest issues related to battery life. I don't think it's the battery. It tests fine, although it's probably the original battery.:nervous: As a full time tinkerer on heavy equip I know a battery can seem fine but can actually be the issue. I'm just looking for all the possibilities before I start throwing money at the wrong places.
Thanks in advence for the help!!!

Not yet. I've spoken with someone that suggested I test both sides of all the fuses individually with a test light. As in, instead of looking for current across the fuse, look for power on each pole. Fuses without test tabs on the back I'll remove and put back in one by one(while car is off) to hopefully re-establish a connection on whichever fuse controls the amp.
Looks like a warmer evening tonight, so I'll be out there later.
I'll keep posting any results.

Problem solved. Unsecure your amp underneath your driver seat. take both connectors out and connect speakers bypassing the amp. If you get a sound than your amp is most likely dead( just like mine). New one $900. used well i cant find one. no junk yard carry them ((( good luck
((( good luckFixed it!!!!
Ok, here's the quick version...
There is 1 large diameter wire that supplies all power to the amp. This is split into the 3 wires that connect to 20, 21, 23 under the floor! I cut the carpet open under the amp to hide the carnage and pulled out the harness, SHAZAM! totally green wire ends. I also checked the grounds, same deal. All is back in and working great. Took about an hour. I'll post pics of the process soon.
BTW, there is a note in the VW service system about this... not a real TSB, not a warranty item... just a note.
Many thanks to a friend at a VW dealer up here in ME for the help on this one!

VW Amp no power fix with pics
First confirm that the connector to the amp has less than 12v at numbers 20, 21 and 23 on the 23 pin connector.
Remove the lower trim panel on the center console using a torx driver. The panel slides straight down.

Then, using either a test light or a multi meter, pierce the casing on the large red wire in the harness for the amp shown above.
If no juice or no continuity between these, keep going.
Note: the ground wires are connected the same way, so check for continuity on these too.
Remove the amp and the plate it attaches to by taking out the 10mm bolts and torx screws. Cut the carpet and liner under this plate to gain access to the goods hidden under it.
![]()
Reach under the carpet and pop all the connectors that hold the harness to the floor and pull the whole harness out from under the carpet.
![]()
The red wire is spliced under the floor into 3 wires and that connector fails. as shown below.
![]()
Cut the wires back until you get to clean copper(it may be a few inches or more)
Reconnect the wires and insulate with your choice of coverings. I used heat shrink connectors with a heat shrink wrap and wrapped that in e tape. I know it's overboard, but I don't want to be here again.

Check the ground wires, they use the same connections.

Note the motivator in the background

Then pull the wires back through, be sure it all sits on the floor in the groove provided, then replace the plate, amp(hiding the cut in the carpet) and trim panels.

Didn't take more than an hour or so and was a VERY inexpensive fix.
Best of luck!
