As the title says, I've found this website which should help c7 owners find their fuseboxes and what each fuse is for.

Hope it's useful :)

Hey Steve. Do you have, by any chance, diagram for relays? I can't find a decent description where is which relay. I'm looking for ABS relays and can't find the answer.

I don't unfortunately 

You see, I don't get it, why Audi makes such a top secret of relays set up. I've searched "a whole internet" and no success so far.

Clearly so the car has to go back to them for repair. It's a naughty way of working 

The fuse box lists are great but what I don’t understand is why do so many systems, eg; Seat heating, have so many fuses in different fuse panels?

it doesn’t make any sense to me at all!

 

anyone got any (sensible ones please) ideas?

 

cheers all

Hi. First post here and sorry to resurrect an ancient one, but I'm looking to wire a dashcam to my early 2017 A6 C7. Will the fuseboxes be in the same places on mine? I'm in the UK and I'm not sure it his matters. Also is the passenger side one under the glovebox or on the side of the dash? 

Thanks for your help

I don’t see why there should any differences, However, we all know Audi likes to keep some secrets!

my dashcam is wired into the fuse panel on the drivers side of the dash, if I remember, I’ll look at it later & see which fuseway it’s piggybacked from

Thank you for helping. Please excuse my ignorance. I'm a complete numpty when it comes to cars and I know absolutely nothing. Is the fusebox where you open the door and unclip a panel on the side of the dashboard?

Hello William,

Please do yourself a favour and stay at least a car’s length away from attempting to wire a dashcam on your car - by your own description of your abilities - disaster looms if you don’t. 
Apologies for stating it as it is, but it’s said in your our best interest. 
Regards,

Gareth. 

Hi William, yes it is.

C’mon Gareth, if the non-technical staff at Halfords can wire in a dashcam, then it should be  well within the capabilities of anyone with basic tech knowledge.

 

as long as their careful & not touch or alter anything they don’t understand of course!

Thank you Gareth, @Magnet I'm feeling like once I locate the fusebox I will be all right. I was confused because my AI kept telling me I needed to use one behind the glovebox with my early 2017 car. It said that the RHD version of that particular iteration of the A6 had the fusebox in a different position and not to use any other one. As I said I'm not familiar so was confused as to why this should be.

 

Thank you @56Doc I must admit that the Halfords thing crossed my mind too. How hard can it be? I will ignore my AI which is probably a good general approach 🙂 

 

 

William.

Make sure you piggy back onto a fuse that is on a circuit switched by the ignition key, unless your dashcam has a suitable battery within it to maintain power when the car is not running, else it will flatten the car battery.

William, 

they used the 2nd fuseway up on the left side on mine.

 

Hello Dave, 

But the OP has stated ‘he is a complete numpty with cars and knows absolutely nothing’ . 
Acid test question:- so would you let him wire a dashcam into your car? 
I’m not forming any judgement on William’s abilities, beyond what he has stated, and I still hold by my earlier  advice, which I believe to be sound in this case.

Regards,

Gareth. 
 

It’s a single wire with a piggy back fuse, the difficult bit is getting the trim off without damaging anything.

its his car after all and I learnt a lot during my engineering apprenticeship by taking duff bits out of cars, fixing them & refitting, or installing extras, lights, gauges, stereos etc.

So why not let him learn? 
 

No I wouldn’t want someone who’s never done it before experimenting on my car. But that’s not the case here is it.

 

As we said before, as long as he’s careful, physically & follows the instructions that came with the dashcam or online There’s no big issue here. 
we all had to learn by doing it the 1st time at some point!

William, be very, very  careful if you remove the A pillar trim if your car has the curtain airbags. As they sit very tight behind it and they’re a pig to get out and put back!

best option is NOT to remove them, just tuck the dashcam wires under the edges.

Thank you for your views Dave, and I think the logic of my advice is clearly indicated by the answer you have given to my question.

No one, but no one, should be advised to fiddle with car electrics without having an experienced person at his side to oversee what is being done, unless they are experienced in doing so. 
Any other advice would not be in his best interest, or the forum’s.

I really don’t feel I can usefully add any further comment s to this thread. 

I understand the different viewpoints here. All my cars have been serviced at the dealers and I changed them often. When I retired I decided to keep my Audi, which I'd had on lease from new, and, feeling the pinch a lot more than in the past I'm more inclined to try some jobs, which I'd previously have had done at the garage, myself.

I am a complete numpty with cars in the sense that I am ignorant of their repairs but I'm not a total numpty in most matters and feel fairly confident of doing the actual electrical side of it, but I was ignorant of a) actually locating where the fusebox on mine was b) how to accessing it and c) concealing the wires once I'd finished.

I am pretty  happy to keep on with the job but my next concern is how to get the wires concealed in the A pillar trim which do contain airbags. I had a look today and there is no wiggle room to safely push them in at the side without at least loosening the trims. I've found tutorials on how to do it on earlier and more recent versions of my car but, frustratingly, not my own model.

Yes that's my big challenge here.

My cars a 2015 model, I think that model run was  2011-2018, so yours should be the same.

I had to move the A pillar trims to fix the compulsory sunroof leak. 
they unclip at the top but then you have to slide it up to release the lower hook. (Very difficult with headline in place) I managed 1, but the other was just too stiff and getting the one I’d  removed back in was an absolute nightmare. The sunvisors need to come off too to move the headlining enough to lift the trim piece. 

If I was wiring a dashcam, I’ve seen fitters wrap some double sided sticky tape round the wire every foot or so and simply stuff it into the gap (with a trim removal tool), it’s how my wife’s Yaris’s dashcam went in! The tape then stops it vibrating loose/free.

given the choice, I wouldn’t touch the A pillar trims again.

 

Long shot but another possibility  is to release the headlining from the front door rubber trim /seal just enough to feed a wire down behind the A pillar trim? It’s pretty crowded behind the A pillar with clips etc to hold the airbag in but it might work, especially if you can unclip the top end of that trim piece and move it towards the centre a bit (1” possibly! ) just to create a bit of an opening. 

NB, the top of the A pillar trim on mine needed to be pulled inwards towards the centre of the car, before I tried to lift to unhook the bottom end.

A set of plastic trim removal tools helped enormously (my son had bought a set luckily).

 

For info - Theres an online parts catalogue (for multiple manufacturers ) at LLLParts.co.uk that might give you an exploded view of the trim and their fixings. Takes a bit of browsing thru their website but maybe worth it.

good luck. 

Hi Magnet,

he’s not exactly planning to fiddle with his cars electrics, he just wants to tap into a fuse way. It’s far less risky than home electrics, which is allowed in law yet ve seen horrendous diy jobs that made me pale when I found them (ceiling rise broken apart & un insulated brass connector block just pushed up through the ceiling is one. Wall lights with mounting screws through the live wire, so the unearthed metal casing became live when the lights were on. (This is in house we’re in now), I’ve had worse, cottage in Cornwall had one power Junction box under the unearthed metal bath, another JB was buried in the wall with 3 wire + earth one side & 2x twin & earth the other. I found by ear when the loose connections inside starting arcing & causing lights to flicker !

 But putting a piggy back fuse into a cars fuse way isn’t making any changes to the vehicle electrics. So to my engineers eye, is perfectly reasonable.

Many thanks Dave, but I think it’s now time to agree to disagree on this thread. 
Regards,

Gareth.

Right. I have changed my plans. Here's why.

I am chickening out of removing the A panel trim for the reasons you mention. However, I can't get the wire tucked into the trim edge either. I have it under the headlining all right but I'm fearful of damaging the fabric if I go much harder on the A panel trim trying to get the wire under it: it is really really tight.

Long story short, I found the passenger side A trim would allow me to run a wire under it. Unsuitable for hard wiring though so I've decided that in the short term I'd now run the power cable down the passenger side and use the cigarette lighter for that. I've managed to get that tucked into the side of the A panel trim and it looks fine. 

I ran the rear camera cable and have it attached to the side of the window with some of the wire grabber things that came with the kit and although not perfect, I can accept it at certainly for now. Given that I don't want two wires there, I'm initially going to also admit defeat on my initial idea of hardwiring the camera and will continue to run the power from the cigarette lighter using the wire on the passenger side  I toyed with the idea of trying to hard wire it to the fusebox on the passenger side but I believe the fuses there are not very suitable.

I'm going to leave this as is for the time being and see how I feel with it for a bit. Thank you everyone for helping me out with it.
