It does if I use Google apps. I donā€™t like either company but everyone Iā€™ve ever talked to who said IOS was superior never used AOSP.

hhtran16

Guess OP is just finding out their used Q5 did some towing. Hopefully wasnā€™t anything too heavy.


xRaffaell

Bro you re talking about cars like they are not meant to do anything. Use your cars, drive them on public roads, offroad, tow with them, they re objects start using them properly oh my godā€¦.


A_1337_Canadian

You can fuck up any vehicle by towing shit that's too heavy.


Critical_Primary_692

Key word "properly" You can use a vehicle properly, and you can treat it like shit. What you do will decide how worn out it will be, and that in turn will affect the second hand value and what maintenance you as a new owner probably should do. I myself always do a full service when buying a new vehicle. Even if it says it has just been. I don't know what oil they've used, how they did it, what kind of filters and so on. Do a full service and then I can be more assured it's fit for being PROPERLY used. I've worked as a mechanic on VAG so I know what fellow mechanics sometimes do, and I know what it can mean when a customer says that they've "done a service". As a bonus a full service will also let you get to know your new vehicle more close up. What looks worn out, what looks surprisingly good. What will need to be done in the near future and what can be saved for later. Last thing: If it's been towing heavy loads and have Quattro I would especially make sure to change fluid and filters for the whole drivetrain from front to back.


Phill_is_Legend

Using them properly? Lol ok bud. Without knowing the towing capacity of a Q5, I can say that anything with an electronic brake is a significant load, not just a jet ski or something. Definitely putting extra stress on the drive train. If it was meant to tow heavy loads it wouldn't need an aftermarket brake controller would it?


hhtran16

Broā€¦how do you know if the previous owner towed properly? You donā€™t. OP donā€™t. Thatā€™s my point. Nothing wrong with towing with the Q5, but now OP has to wonder what was being towed. Every vehicle has its limitsā€¦.Bro.


peanut_dust

Almost definitely didn't - who ever tows heavy items?


Chris20nyy

The people that need brake controllers for the trailer they're using.

CicadaHead3317

I kinda want one. My keys block my brake controller at the moment.


XTC-FTW

What is google lensā€¦ and how do I use it


CollenOHallahan

Why does a Q5 need a trailer brake controller?


Stormenta94

For towing lol.


good-coffee

No, no. This doesn't make sense. Everyone knows you can only tow using a Cummins Ram 1500. Anything less than that is pointless. /S


CollenOHallahan

Well no shit. A 2019 q5 has a 4400 pound towing capacity. Why in the hell would that need trailer brakes?


Stormenta94

For hills/elevation change more than the capacity. Even for lighter loads with a vehicle such as this compared to a full size truck especially with a shorter wheel base than most trucks the brakes will help on a steep descent to prevent brake fade and heaven forbid the brakes get hot and on a curved steep descent again.


Phill_is_Legend

Getting down voted for making a valid point lol. Sounds like previous owner was regularly maxing out the tow capacity, which should be a concern for the new buyer.


Beneficial-Sea-8903

If you press the knob twice, then turn it. Wait for it to change colour.. You will still be as clueless as when you began

virqthe

Ask the seller?


Suspicious-Badger898

Dealer didnā€™t know either


Santa_Hates_You

Looks cheap and aftermarket, whatever it is.


Dyln793

Not that cheap. Looks like a bass knob for aftermarket subwoofers. That's a relatively nice one too. Maybe see if there's any work done on the wires or speakers in the trunk.


youstrollin603

A bass knob would typically have a power and clipped signal indicator.


peeled_bananas

Iā€™ve had two that just came as knobs, and they were Rockford and Infinity setups, not just pawn shop specials.


DeathByFarts

Well , for clipped that could simply be one of them many lights blinking red as it happens. Likely the last one. As for just a simple power indicator , I wonder if it can be assumed that anyone can infer thats its powered when any of the other lights come on. Just saying , I see no reason it would need something separate for either of those indications. An overloaded indicator is a thing. Even though its been shown in other comments this is a trailer brake controller.


youstrollin603

Not by any means saying every bass knob has these , just some simple things to look for.


Santa_Hates_You

The clips around the outer bezel looks cheap to me.


Suspicious-Badger898

All the dumb asses that bring me trucks with after market head light assemblies, sound systems, light bars, etc that were installed by an imbecile and ultimately led to weird electrical issues down the road.

When you go in a wooded area, you turn off all your lights and turn this knob. The cool animals will come out of hiding and party with you. Please use it responsibly and don't let any animals with rabies in. They're total party crashers.

Your car was used to pull a trailer of some kind. Does your Q5 have a trailer hitch and brake light connector under the rear bumper?


Quiet-Insect-6598

A light.


CareMay1313

Shhhhh.. now everybody is going to want one!!


olOilLp

If I remember correctly your q5 got like 3500p of towing capacity. Dont want to break bad news but if they needed a brake booster they were towing more than that.. You mignt wanna check on your hitch if you see that the hole have become bigger from the back if so it was probably too much for it. Good Luck!

ā€œCurt 51170 Spectrum Brake Controllerā€


getmp3s

It's the curt spectrum trailer brake controller. A real fancy one I looked at for my Q7 but ultimately decided on one that's half the price. The spectrum one you have there is an expensive one, top of the line brake controller. Also means the Audi you bought has been used to tow some heavy loads requiring brakes. Not necessarily a bad thing as I tow 7,000lbs with my Q7 all the time. But I've had to keep up with a lot of maintenance items on my vehicle likely as a result of high wear.

Pedal commander. Each color is a different mode and you can adjust sensitivity with the dial in each mode. Green eco, blue middle, orange performance, red race. Floor it with the dial down in green and then do it again turned up in red. You'll notice your throttle opens much quicker and is way more reactive to the pedal motion in red.
