034 Motorsport - Billet Aluminium DSG Breather Catch Can Kit - Audi 8Y A3/S3 - 034-504-Z037.

The 034Motorsport Billet Aluminium DSG Breather Catch Can for the Audi 8Y A3/S3 replaces the tiny OE plastic vent and prevents transmission fluid from being forced out and splashing around the engine bay. Any transmission fluid that is collected in the catch can drains back into the transmission. Improve the appearance of your A3/S3 engine bay by installing this beautiful billet catch can and eliminating unsightly oil stains.

The 034Motorsport Billet Aluminium DSG Breather Catch Can for the Audi 8Y A3/S3 replaces the tiny OE plastic vent and prevents transmission fluid from being forced out and splashing around the engine bay. When the DSG heats up, especially when launch control is used, it is common for DSG fluid to escape through the breather hose on the transmission, coating the entire underside of the hood and engine bay in DSG fluid.

The 034Motorsport Billet Aluminium DSG Breather Catch Can addresses the issues with the factory breather, allowing for ample system breathability while trapping any fluid that escapes out of the breather hose and draining it back into the DSG. Installing this beautiful billet catch can will improve the appearance of your A3/S3 engine bay and eliminate unsightly oil stains!

The body of the catch can is CNC milled from 6061-T6 billet aluminium and black anodized for a durable and stealthy finish. Internally, a stainless steel baffle plate prevents transmission oil from escaping the system. External mounting brackets are powder coated to prevent corrosion and enhance appearance. The OEM plastic vent hose is replaced with an 8mm I.D. silicone vent hose while retaining the OE connector at the transmission. Finally, all mounting points for the DSG catch can are stock mounting points, which makes for an easy installation with no drilling or cutting necessary.

Features:

  • 6061-T6 Billet Aluminium Housing
  • Black Anodized Finish for Durability and Stealth
  • Stainless Steel Internal Baffle Plate
  • Powder Coated Vehicle Mounting Brackets
  • 8mm I.D. Silicone Vent Hose
  • Retains the OE Connector at the Transmission

Good solid product
Purchased in February of 2025. Very solid item. Use it constantly in our 2011 4Runner and 2017 CX5. This unit attaches firmly to vent fins in both cars. I use iPhone for maps programs and streaming music. When traveling I'm constantly rotating device 90 degrees to use phone in portrait and landscape positions. Unit has shown no signs of losing ability to firmly hold desired position despite frequent rotations. It holds firmly where you place it. Initially I had concerns about placement on dash and blocking view of radio face, clock, MPG indicator, and other displays. Didn't take too long to realize the flexibility of this thing and the many, many positions you can place it due to multiple rotational joints. Pricing was fair. If this ever wears out, I will want to buy another.

Happy with purchase, easy to install, exactly what I needed
For many years, I'd been using a similar item with a wedge-type vent mount that finally stretched out and became unusable. When searching for a replacement, I wanted to try one with a different type of mount and I looked at many brands/types of holders. This one seemed to be the best item for the price ($8.99 at the time). So far, I'm very happy with it. I got it in a timely manner, and it was exactly as advertised. I had no problems attaching the hook to the vent fin and securing it. I use it for a GPS, and since the holder is designed to stand out away from the vent a bit, my device is easier to see than previously and details are easier to read. It wobbles, occasionally, but the holder's not loose, at all, and it doesn't affect my ability to read the device. The frame is barely just big enough to hold my GPS, but so far that hasn't been a problem. The device slides into the frame easily, locks securely, and stays put. The holder pops open at the touch of a button on the back, and the device can be removed easily, without issue.

Prevents me from adjusting the air vent up or down
It's true that it doesn't block the air flow. I had to put it on the left passenger side vent to retain the ability to point the driver's air vents where I want. With it over there, I have to turn my head too far to the right when I'm driving to see my phone, and the passenger can't adjust the vent up or down. Also, phone can't tilt as far left and right as other ones. Good price, unique design, easy to install, feels sturdy, holds iPhone SE fine, and doesn't block my view of the entertainment system.

BETTER THAN A CUP HOLDER
I had a cup-holder mount and it was always falling apart. No matter how it was turned, to unfasten my phone I had to move the spring part of the holder in the same direction that removes the entire clip from the stem of the mount. Of course, I eventually lost the clip. What a bad idea. And, in a 4-Runner, on my cupholder, MAPS sometines got lost and I would have to hold my phone up to the windshield for a minute to get back MAPS back on track. Also not a good Idea. We're not supposed to be handeling a phone and driving so holding my phone up to the windshield is kinda like flagging down a cop. (The 4-Runner has hand-free phone service, as well as some kind of circuitious navigation but it's always lost.) . So, for about $9 on sale, I though I would try one of these LISEN mounts. It works great ! Really. Easy to attach securely but scratchlessly it to my center AC/heat vent and It is infantly moveable. Swing the arm 360 degrees, in and out, phone up or saideways, and tilt the phone to me or the Boss. If I get bored, I can relocate it anywhere along the center vents, or even over to my side vent if I have nothing better to do.. It is sturdy, quiet, easy to clamp in my S21, and release is simplye by pushing the button on the back. Sooo much better that my previous mount, for a third of the price. It might be the best $9 you ever spent. And still worthwhile,if you have to shell out the $18. (But I always try to avoid paying full price for anything). Enjoy !

Usable but average, with only basic build quality and stability.
This in-car phone mount is fairly average overall. It’s easy to install and works for basic navigation needs, but the build quality isn’t particularly impressive. The materials feel a bit ordinary, and stability can be an issue on rough roads, with some looseness over time. It’s usable, but not outstanding.
