I wired mine a few days ago. I used a universal 119190kit that etrailer that works with German cars. As another member posted earlier each turn signal and brake light work together and will have to be bridged near where the shock is connected to the rear passenger hatch. You will have to remove the rear interior pillar which is just clips. Once removed the black/grey and black/orange is the turn signals and brake. you will need to bridge those two wires with enough wire to reach the lower panel opening so that you can mount the trailer kit. since it is a two wire system you will ground the white cable and red cable to the existing ground nut right inside the access panel. I ran a power cable to out the little rubber grommet at the bottom of the passenger side compartment. The tricky thing for me was finding a wire for the running lights. I found the lighting wire for a side light but when the rear hatch closed the power went dead so I could not find one I could bridge to for lights only. Instead I found a wire that would cut on and off with the engine and it works fine. The only issue if you want to consider it one is that the trailer lights are on when hooked up and car is running. Day or night. For me I like it better because it makes the trailer more noticeable with the lights on. I just loaded some new pics of the Q3 with the trailer if you want to look at them. The hidden Hitch you got is the same as the Draw tite and Reese. I went with the Reese because the people I bought it from had that one in stock. Hopes this helps.

You have to remove the original bumper and replace it with the hitch. Is that a concern for anyone?
Actually you only have to remove a clipped cut-out (for a hitch) in the bumper cover - it's not so hard ...

I'm going to be in the market for a hitch that will be used only for carrying bikes. I have the bike rack (Kuat 2-bike) already as I got it for my wife's car. It fits the smaller sized hitch (1.25") but has an attachment that allows it to fit the larger hitch (2.0") as well. Not sure if size matters here and whether I should care about small Vs large for the Q3 if there's a choice? I thought I'd simply head down to the shop that sells bike racks and hitches...but if there's a specific recommendation from you all here I'm all ears.

Can someone describe how to remove the interior trim panel (the one with the speaker grill) in order to access the wiring in the passenger side near the tailgate?

This is mentioned as being held by clips but I really don't want to break the panel by trying to remove it incorrectly.

Thanks,

Steve

Ok, pulled quite hard and got the trim piece removed.
Anyone know the wire color for tail lamps?

Thanks

Wiring installation - for reference, here is additional information. The wire for the tail / running lights is located on the tan connector, low on the rear of the wheel well and easily accessed via the passenger side interior removable panel (grey with blue stripe). This works with lift gate open or closed. A few inches above it there is an unused ground terminal. Power +12 V can be routed under the trim from the driver side convenience plug in the removable interior panel on that side across to the passenger side - routing is easy with the spare tire and foam surround removed. For completeness, as others have noted, the L & R turn signal wiring is under the upper interior rear pillar panel on the passenger side. Removing the panel takes some amount of force. The turn signal wires are black with orange stripe and black with grey stripe as others have mentioned. The brake lights are integrated with the turn signals. Brake and turn signals will only work with the lift gate closed.

Last year, my friend too wanted a trailer hitch for his boat transport purpose. So he contacted to various reputed boat shipping firms, for which you can hop here, regarding the kind of suspension he should attach to his Audi Q3 so as to comfortably transport his boat.

So, In conclusion you just have to pull hard? I'm about to taking it off to do the wiring and I just want to be sure I just need to pull it out.

For one you do want to buy an interior pry tool just to make sure you don't break anything. The other option is to find a way you can make your own pry tool if you want a cheaper route, might be possible to use some house hold stuff.

I just installed the Drawtite on my 2016 Prestige and the rear valance is completely different than what their instructions show so we had to cut blindly!!

Because of how the tabs for a trailer chain drop off the actual hitch the hole had to be rectangular to get it over it and to clear hitch all around.

Overall very happy with the install and it works perfect with the Kuát Sherpa 2.0 bike rack. even better the hatch will clear the rack when it is not in use and folded up.

Looks good! I'm wondering how low is the receiver compared to the exhaust? It looks like they are about even? Some of the other hitch options seem to hang way low.

Also on the rear valance I have a pop out. I think this has something to do with the S-Line trim (and literally looks like it is there for the European hitch option so it covers the hitch when not in use). Did yours have a pop out? It looks like it doesn't.

it sits about the same as the exhaust so no chance of the bike rack dragging like I've experienced with the Curt mounts. I didn't notice a pop out on mine and the 2016 prestige comes in the new S-Line trim

OKay I am new to Car DIY; (Except applying some chrome finishes). I want to install a Trailer Hitch to my 2015 Q3 (Majorly to attach a bike rack; this thread is the single source out there which is strange but hey; thanks you all.

So as I understand,

Audi has one OEM part for this; which part itself is $800;($640 at few dealers), WOW. There is no cutting required for it.(I assume)
Than there is one from Curt (12254); which uhaul also sells under different number and is hard to find at uhaul. Lower bumper need to be trim for this.(Or is that a clipout as @Roger mentioned?)
There is one from Drawtite (But that one is installed on 2016 Model). It seems it is better over Curt but will it fit in 2015.
And there are others as mentioned by @rdboles (reese, hidden etc). Does not require any trimming of bumper?

I have bought the Genuine swivelled trailer hitch from Ebay very cheap and also bought the Westfalia wiring harness specific for Audi Q3, everything installed correctly and working. Total cost with all package was about 450GBP.

Finally I'm happy having another factory part retrofitted.

My car didn't have towbar preparation, wiring connection was made according to Westfalia manual and socket connections according to factory wiring diagrams. Everything works as it should, like factory. The wiring kit supports CAN-BUS and when towbar isn't locked, you get a notification on dash, when flashing alarms, you get a different icon on dash, when a bulb is not working, you get indication on dash also?It works like factory. On manual it says that you must go to a dealer to have SVM coding, but it's not necessary. With VCDS you can enable module 69-Trailer on 19-Gateway Intallation list and put coding as per Westfalia manual and enable Trailer Stabilization on 02-ABS module adaptation. I bought the blue connector in order to connect the green/red LED indicator on the release lever according to factory wiring connections.

The good thing about Westfalia wiring kit, is that the unit included supports LED trailer lights, as far as I know factory unit does not support.



Part numbers:

Westfalia wiring kit: 305410300113
Factory towbar: 8U0803880B
Grip for release lever: 4G0813961
Bracket: 8U0813685
Handle shell: 8U0885671A
Hex bolt: N10009205
Fender nut: N90817302
Blue Connector: 6Q0972883C

Total cost about 450GBP including the connections by a specialist I will post photos from my car when connecting LED, I'm waiting for some repairing cables to complete setup, LED is working because has been tested.



Can share wiring plans if anybody is interested!

Here are the photos after 100% completed retrofit.

My can didn't have factory towbar preparation, so no sonnectors on rear both sides on trunk, all connected on Westfalia's Trailer detector unit, which is exactly the same as the factory
