A4 - Fuse keeps going. 12V

Xithus

Hi all. Wondering if this has happened anyone else. I've a A4 with all 3 cigarette lighters connectors not working. I replace the 20amp fuse, they work and then shortly after the fuse goes again with nothing plugged into them. any help would be appreciated, thanks.

If it's blowing fuses like that you have a short somewhere have a close inspection of the cigarette lighters make sure nothing is shorting them out.

If that doesn't work you can start by disconnecting them one at a time and see if the fault disappears if it still happens it's a fault in the wiring somewhere.

There’s nothing else aftermarket running off that circuit? Dashcam, Bluetooth kit etc?

Thanks.

At the moment I've nothing connected like that. Although a tow bar was fitted that seems to have some electrics going to it.

Most things that plug into cig lighters have crap cheap plugs, the pins or other metal parts can fall out and get stuck inside the plug and short it out.Have a good look inside them.

I second this the amount of cars that come into our place with bits that had falling into the cig lighter causing it to short is common. Get a air line and play the 3 of them out and you will be grand
