Questions you thought were too dumb to ask

[igxqrrl]

Every car I've had has a headlight indicator in the dash. My used 2017 RS7 doesn't. Is there supposed to be a light that comes on when the headlights are on, and maybe it's just not working on my car?

I don’t think there’s an actual indicator besides that your dash lights up i.e The cluster is illuminated

Here’s a ‘dumb question’ (o.k., two dumb questions): What causes this noise??? I have a 2018 A7 Prestige. There are no problems with the car. This is just something that I am curious about. I have noticed that when I drive the car and accelerate, as soon as the car gets to the speed of 50 MPH, I hear something, maybe some sort of actuator, do its thing. It’s a brief sound, about 1 second in duration. The sound seems to come from under the center console area. I don’t notice anything different about how the car rides or accelerates after I hear this actuator. And, if I then slow the car down to a stop, without turning the car off, then accelerate again up to 50 MPH, I don’t hear the actuator a second time. Does anyone know what this noise is? And why does it only occur once per drive?

I have a related question on my 2017 S6...

I could swear that the "Passenger Airbag Off" light was never illuminated, even when I drive alone. And then recently I had my battery replaced. After that, and perhaps completely coincidentally, I noticed that the light is on all the time when I drive alone. I assumed that it was a glitch following a power interruption or spike when the battery was replaced. And then I read the owner's manual and it says it SHOULD be on when no one is seated there. So I test it out, and sure enough, if I sit in the passenger seat, the light goes out.

Is it possible that the light was off before the battery was replaced, and now it's on (as intended)?

Things that make you go "hmmmm"

[Audisthesia]

There's a sensor in passenger seat, PODS... Is there anything in your seat or is it empty? Reset the error code and see if it comes back on.

[Speedooooo]

Did you get your PODS sensor replaced during the recall? Depending on what I place on the passenger seat the light also goes on and off.

Being a new C7 owner (2013 S6) with three days under my belt I’ve gotten two questions already.

First; The Bose systems seems to be lacking in bass and depth even at full volume. My S4 with Audi’s concert system was a lot better. I don’t know if the subwoofer is shot or if something is up with the system. I’ve adjusted the bass to max and messed with the treble. No middle adjustment although. Our 2014 Acadia with a Bose systems is miles ahead. Anyone have some insight for me?

Second question; I’ve noticed atleast twice every time I start the car I can hear what seems to be a ticking sound behind the driver’s side rear seat. I assume it’s the air pump? It doesn’t do it but once for about 20 seconds and it’s done. Is this normal or an indication of something? No faults for the air suspension.

Stupid question time (and not worth a new thread):

1) From what I’ve read, it sounds like the APR tune is a bit more conservative than some of the other options. Has anyone heard any horror stories about it causing issues? I’m cool with a more conservative tune, would just like to wake it up more. Would I need a transmission tune as well?

2) I’d love to slap a catback on this car, it’s the first car I haven’t changed the exhaust on. My hearing is starting to go a little bit so I try to be careful with that. Has anyone managed to only swap the tips and make it look clean and not trashy? I feel like I usually see that on lousy rebadged cars, I’d just like quad tips for aesthetics and a new diffuser. Any input is appreciated.
Thanks

Regarding the stereo, I don't know it is exactly the same as my Bose in my 2016 A6, but I can barely see out the rear view mirror when the bass hits. I think it moves all the mirrors. The only comparison I have is my buddies 2017 A4 Bang and Olufsen and mine murders his. It actually seems like someone stole his woofer.

I can't help directly, but there are several AZ members such as OlyS6 who have great knowledge of the sound systems. In general their criticism of the Bose seems to be more about the amplifier, not so much the speakers. Like WatchMeSpend, I get decent bass volume from my Bose system so maybe your subwoofer is indeed disconnected or shot. Others will have to offer suggestions on how to test the system.

From what I've read, all the off-the-shelf stage 1 tunes from all the tuners perform about the same, so cost and convenience may be more important deciding factors. Most people encourage a TCU tune as well, although that seems to be more important for the DSG transmission even at Stage 1, not as much for the tiptronic.

If you don't have access to anything higher than 93 octane, it seems the difference is price and flash from home options for a dual pulley tune. it looks like APRs competitors have more aggressive "Stage one" tunes" that produce more oomph than APR, but when they go to a Stage 2 dual pulley the difference doesn't seem to be as great as with APR. This doesn't mean the others are worse, in Stage 2 builds, it just looks like the difference is less between competitor's stage 1 vs stage 2 tunes of EQUAL octane and stock exhaust. Remember you have a CREC engine that limits your tuner options.

There are enough guys running APR stage 2 DP on stock exhaust pulling in some of the best 1/4 mile times that nobody should worry about APR.

I guess that’s an upside of not having DSG hahaha

Thanks to you guys for the insight. If I have time today I’ll check out fuses and what not. Maybe see if I’ll get to physically looking at the sub and amp to see if anything looks “off”. I’m not a very big audio guy as far as technical stuff. I’m just an enjoyer of good audio quality.

i run apr's black diamond exhaust tips on mine and i think it looks clean but i only have dual tips not quad

[Speedooooo]

I did quad tips and got an S6 diffuser. I did chop off the mufflers so it’s a bit loud and drones. You probably won’t like it if you’re already sensitive to that.

[Glicious]

For awhile I thought my high beams weren't working then finally realized the indicator would come on occasionally when they auto-engaged.

I bookmarked this a while ago: https://www.youtube.com/watch?v=x8YGujHDLVM

Have not done it though.

That looks amazing. Did you just take it to an exhaust shop?

I think more accurately the issue is that I’m not sensitive enough to it haha. I keep toying with the idea of exhaust but any extra noise for a long period of time is something I’d like to avoid.

TY! Yes I had an exhaust shop cut the mufflers and weld on the new tips. I told them I wanted it pretty flush. If I had to do it again I might not have deleted the mufflers and straight piped the center x-section instead. However, that won't give you that quad exhaust look.

[reighnman]

Is the oem rs7 diffuser always carbon fiber? Just noticed mine on my c7.5p is painted black so wondering if it got damaged at some point and they painted it.

[widebodyfx]

Not always carbon, there is a gloss black lower section with the trim pieces coming in various colors like silver, black and titanium.

[reighnman]

Ops meant specifically the rear unless that applies as well.

[widebodyfx]

Yep, was talking about the rear as far as the trim pieces along the top of the bumper. The front center and side pieces come in those 3 colors plus carbon no real trim piece to add to the front.

Example of a titanium edition RS7, gloss black lower with titanium trim. This car would've needed the carbon pack to get the mirrors, front and rear pieces in carbon. The carbon rear diffuser is one piece, unsure if the other options are all one piece or not, have just seen the variations.

[reighnman]

Cool thanks!

Anyone here cut open this closed off spot in the grille to allow for air to go straight the intake scoop?

Also side note, I just did the passenger side spark plugs and I was pretty surprised to see number 2 (?)/ second cylinder from the front had nearly no carbon on the piston face. The other three had some carbon build up. Little surprised to see that on one cylinder only.

Something to consider is that the airflow has been optimized by engineers for a reason. I would not mess with it, as cutting things without a sense could lead to turbulence in the airflow or a certain resistance we can't evaluate properly.
Better off leaving well enough alone there.

It's like driving without the hood on for better cooling. Seems like a great idea, right? Except you'll have no cooling through your radiator where you really need it.

Yeah I get it, hence the question. It’s a small spot up top directly in front of the ram scoop, and while you’d think it wouldn’t affect air flow, I didn’t want to cut it without having some opinions on it. I didn’t think it would affect things that much being as it’s three of the “diamonds” in the grille, but if anyone else may of done it I was curious. Probably wouldn’t gain anything noticeable anyways…

Removing the hood for cooling is a bit of a stretch as a comparison for my question lol

Q found it counter productive to remove the inserts in the ACC area in his thread for cooling in 4.0TT. May queue into that for engineered air passage for the engine

Presumably the manufacturer does extensive wind tunnel testing to study airflow. I imagine there are compromises though between the function engineers and the aesthetics marketing folk.

Well, passenger side is blocked there on my S6, but it is open on RS6 as they have an additional cooler that gets air from there. German engineers are pretty good..

cant install until I get back to the states....Im still floating off the coast of Italy, and wont be home for.......4 more months? maybe.....

[Audisthesia]

you did, i waiting patiently for install pics

[hunter_killer]

I was thinking of just opening up a section by the scoop, I wouldn’t remove the whole blockade. I could see the whole thing being removed causing a negative effect. I don’t have any images or results of how the air flow exactly moves up under the hood/ top of the radiator and intake scoop. Good intentions I suppose.

Those are things I REALLY wouldn't touch.
Its would be like adding additional ducts for brake cooling. Think the engineers didn't think it through?
Or a huge wing on a Honda...mmmm. Not gonna help you stick like an F1 car. And that ricer pipe doesn't make you faster, just more obnoxious....

Well brake ducting can be argued, but no need to get into that. Engineers aren’t always out for the best performance in every aspect… I’m glad for the discussion on this and getting opinions on them. I’ll just leave the idea alone.

I just got my first Audi, a 2016 A6 Premium Plus 2.0t. When I bought it the backup camera was not working but the parking sensors work fine. I have searched and read multiple forums and seen tons of pictures of where the reverse camera control module is located. Almost all say it's in the right rear qtr in the trunk but when I pulled that panel the only things back there are the fuse block, the Emergency Parking Brake and the Comfort control modules...nothing else. Now most if not all of my previous searches were from prior model years. Can anyone tell me exactly where the Reverse Camera Control Module for a 2016 A6 is located? Is it possible its under the front passenger seat?

Thanks in advance!
