Does anyone here own an Audi A8 (or I guess this may be applicable to an Audi A6 since it's similar in engine bay design).

Where do people run their sensor head cables and such into the main cabin? Is there a grommet you remove, and where do you run it into the front cabin? Drivers or Passenger side? Any insight?

^No, the above is not my car. However, I'm evaluating if this is the right car to me. #1 on the list is ease of install for the ALP, LOL (I wish I was kidding, but I'm not).

Thanks

Booo DeWalt... I've found that most VW's have a small grommet through the firewall filled with a plug. Usually on the battery side of the firewall, I'm assuming Audi would be the same? I only know of 1 person on here who has done an ALP install on that car. I think he got it professionally done though.

I actually did have to use a drill to step our the factory hole to 7/8" to easily get all the connectors though..

It should be fairly similar to this write up. Most Audi's use similar ECU and pads through points and although it may not be exact, this should get you 90% of the way. I am about to do this install on my own S6 and can't wait to be protected :). Hope this helps!

jdong had an ALP install done on an Audi A6. Not sure how similar those are to the A8 though.

There should be a grommet for wires under the floor panel or by the brake booster somewhere similar. Look for a cut out there (goto the dealership and look if you don't have access to the car). IF not, you'll have to drill a 3/4 hole to pass the wires through.

As for running the sensor wires, I would run them along side the car and strap them to something that doesn't generate heat.

I hear it's a lot easier to install on the S8 than the A8 ;)

Seriously though, if you are still looking at moving over to Audi, make sure you find one with the Black Optics package or equivalent. Less contrast between the heads and the grill, and fewer opportunities for damaging reflection.

Let me know when you get the car!

FUC* So I just spent 5 hours today trying to figure out how to get through the firewall. I found ONE point, but it's going to get wet, quick, as it's right underneath the windshield. Even if I silicone the crap out of it, I'm worried, seriously, about water penetration.

Has anyone run wires underneath cars and then past the brake boosters and such?

I'm losing my mind.

I have the 2019 A8 in my garage right now. (on loan)

@angrypenguin is your battery in the trunk on that car?

I have some cables for an electric oil pump routed from my engine bay to the rear of the car. My fuel lines run under the car and have a protective shroud protecting them so I ran the cables along that and then routed them up through an unused grommet in the rear.

Getting cables from my engine bay to the cabin was a pain because I had to remove the air box, battery, battery tray, and fuse box. But once I got to the main harness, there were a clue of clitorises on the rubber grommet that are there for extra stuff. If you cut off trhe tip of it it's an open sleeve for extra wires. You may have something like that on the main wiring harness grommet. . Might be buried under plastic and other parts tho.

Try looking underneath the passengers side floor panel for a grommet. The wires will drop below the car so be sure to protect them with either the rocker panel or a couple rounds of hard cased wire sleeves, then snake them up and thru the engine bay.

I'll take a photo later, but there are 0 unused grommets on this car in the firewall. Big frigging zero.

SIGH. :(

You may have a min grommet with an auxiliary "nipple"
In the attached pic, the main grommet has a tiny nipple that you can cut the tip off and add a wire/cable that ends up in the oem grommet/wire harness.

Have you seen this?
Installed Radar Detector (and how to get through the firewall) - AudiWorld Forums

From what I can tell, he just straight up ran it through the oem grommet along with the rest of the wires.

So yes I do have that. Are you sure those nipples are not for the sole purpose of pulling out that master grommet?

You can drill your own hole in the firewall as long as you seal it properly. That's what the install shop did with my car.

I have only ever seen them usedused to route extra wires since they tend to be hollow. I have removed and replaced those grommets without ever needing to use those nipples or even considering they were for inserting the grommet. Maybe the factory robot can use them but no clue.

So. In short, no I am not sure that's what they are for or not, but I personally have only seen them and used them to route extra cables.

Alright folks, thanks to all for your help.

7 hours in and I have figured it out. Oh I'm fairly certain some of you will laugh at my post. I'll do a detailed write up when I have a chance to breathe.

And I managed to put it all back together :D

Time to go and enjoy the car tonight....see if she's worth her price tag :eek:

The Audi almost won but I put up a good fight.

My hands are a victim of the war.

I violated the car, badly :D
