Please remember don’t post photos that show your license plate, house number, or any other info that reveals where you live.
Cropping or blurring plates, removing location metadata, and avoiding shots of your driveway/front door keeps you safe and prevents thieves from having an easy target.
If you want feedback on your car, upload close-ups of the car itself (wheels, engine bay, interior, etc.) or take photos in a public spot without identifiable landmarks.
Just keep in mind... car thieves are smart and patient; they’re always waiting for someone to slip up.

Just starting to add stuff to my Q70's exterior need opinions on if this splitter I installed. Does it compliment my car or is it too flush and have no impact on the visual. It's a Q50 splitter since there's very few Q70 aftermarket parts. I'm still trying to decide if I love it or not. Need opinions and suggestions.

My valve body went out recently and I plan on just completely vr30 swapping the trans instead of buying a valve body. I just was coming to here so I don’t miss any steps or parts. anyone who had done something like this before some help would be great. Just wondering a list of parts needed to complete this, I plan to take it to a mechanic and have him install it but I know there is more that goes into the swap than just simply the trans. I apologize for my lack of knowledge but someone who knows a little something about this would be greatly appreciated!

Was wondering if it sounded normal and healthy for a VQ engine is fairly warm
r/q50 • u/That-Visual-2681 • 17h ago

Can i just buy the 2018 or up screen and replace it with my old one? I see the non oem ones (aliexpress boards that are mixed with the oem etc) that are for 250eur or more but also i see some used Q50 +2018 screens for 400eur
Samply my questions:
Will it work an +2018 oem car play with my 2014 diesel work?
If it will not work it is possible to know a mod to add car play similar to the 2021 version shown on the screen?
Sorry for my bad english hope my question is simple

Hey guys I’m tuned and I recently got this got I was wondering what you guys think it could be? Would it be a bad sensor from downpipes?

How long have you been tuned with racebox and how is the tune on daily basis? Have you run to any issues that i can expect?

I have the JoyeAuto module installed but it doesn’t show the CarPlay. All factory settings work & I see the CarPlay on my phone Bluetooth but can’t get it to show on the screen. Am I doing something wrong or do I need to get a different module that pair well with the Hybrids?

Not the most glamorous photo but this is my 2015 q50S 3.7
I’m not looking to do any performance mods as of now but I do want some cosmetic mods like taillights, headlights, carbon accents, where can I find high quality parts for this platform for a reasonable price. I’m from Canada if that makes any significant impact on imports
Currently looking at a 1-owner 2020 q50s rwd with carbon fiber package and is a couple hundred miles under 19,000 for $28k OTD.
Is this on par with current market or am I ridiculously overpaying?

I need help trying to diagnose this grinding sound I’m hearing on my right side of my car. It sounds like it’s coming from my rear brake, I went and remove the tires and checked both the fronts and rears pads and rotors and did not find any damage. I first started hearing this sound about three days ago, and it sucks because I only have an hour of daylight after work to work on my car so I haven’t found any answers.
When I’m driving the car, I don’t notice the sound until I engage the brakes, but I do notice after releasing the brakes, I still hear the grinding sound for approximately 5 to 10 seconds. I also noticed that, depending on how hard I break, it increases the sound of the grinding/scraping noise kind of like in the video.
If anyone has any idea what this sound could be or advice on what areas I should be looking in, I will greatly appreciate any help.

The lane keep assist on this car is great, there were some stretches on the interstates where it kept me in the lane with no intervention for over half an hour, basically a Tesla 😂
r/q50 • u/Alternative-Pause937 • 2d ago
So basically everything was running smoothly since I started driving but I was literally just like going 15 in some traffic and all of a sudden it almost felt like someone was tapping the break as I let off the petal at first I wasn’t paying attention to my gears or anything just tryna get out but after I pulled over it didn’t feel like it was when I let off the gas, it just wouldn’t shift into first. I turn off the car and back on and a check engine light pops up. I used my code reader and these the codes I got. Just got the car used at 120k miles and learning more about these cars go figure this happens immediately. Any help would be appreciated ask me anything

I just switched from a 2014 to a 2018 q50. The 2018 tire size is 225 55 18. I bought new winter tires last year that are 225 55 17. Can they safely fit or will they even fit. Thank you
