Purchased my second V today…in the course of the 5-hour drive home I identified a few electrical gremlins. It is an ‘11 Coupe with Recaros that is bone stock.

The following things are on the fritz:
  • Driver’s seat fore/aft movement. All other motors work As does the memory recall.
  • Neither of the cooled seats work
  • The 12v socket under the HVAC controls ( behind the little door) has no power. The one below the armrest works.
  • Some of the backlights behind some of the radio buttons flicker intermittantly
  • Weirdest of all-if I turn on the headlights manually, only the headlights come on, the park lights/tail lights/license lights do not come on. It all works fine on automatic control.
Anyone have any suggestions as to where to start-could some of this be related?

Thanks

No floods. I know the whole history of the car.
I think I remember a similar situation I read here a while ago, turned out to be a shorted wire under the driver seat, possibly from the courtesy in/out function or just different drivers adjusting seat. Possibly check that area? Maybe a body control module?

This gives me fear as my whole front end and engine is out. I worry when reassembled I will deal with some sort of electrical issue.

At least there are several threads dedicated to solving these electrical issues. I recall poor grounding, fuse box, loose connectors in the console, ECM pin bent, ECM failure, shorted seat cable...

Also there is a tool that is available to find shorts in electrical systems. Can't remember what it is called but apparently works well.

Update: The front 12v outlet was a fuse in the underhood fuse panel. Fixing that had no effect on the other items.

I looked under the seat as best I could and everything seems good…clean, tight connections, no frayed wires, etc. Activating the fore/aft seat switch gives a ‘click’ but no other noises. The passenger seat works fine.

Update 2: The seat fans was the ‘Ignition’ fuse in the underhood panel (#62)

I have now verified with multimeter that all fuses in both panels are good.

Update 3: Seat fore/aft now working. Coming out the side of the seat motor there is a rubber “sheath” that I assume is covering the cables that move the seat. I twisted the outboard sheath so it spun around the cable and then the seat worked. Cant image how doing that affected the operation, but it seems fine now. We’ll see if it lasts. Fortunately I am the only driver so the seat wont need to move much now that I have set it in position.

Gremlins...They put em in cars, they put em in yer tv. They put em in stereos and those little radios you stick in your ears. They even put em in watches, they have teeny gremlins for our watches!

But I was told Gremlins only come in god damn foreign cars! What are they doing in a fine piece of american machinery???

Just make sure when you find them you don't feed them after midnight or get them wet!

There's a bolt inside the fuse box in the trunk that could be loose. The fuse box is above the battery and the bolt is in the middle of a white box.

May not be the answer to all your issues but it solved the issues I was having with my whole center stack losing power.
