r/GLI

Like many owners I’ve seen in this sub, I’d been suspecting for a while that the stock “VW Premium Audio System” subwoofer in my 2026 GLI was broken, because I literally could never hear any bass coming from it, even with the subwoofer setting maxed out in the EQ. Changing the sub level made absolutely zero difference to what I heard.

Today I finally took the subwoofer apart, and honestly I was shocked by how absurdly cheap this thing is. The enclosure itself is huge, but once I removed the cover, I realized the actual subwoofer inside is just this tiny little speaker sitting in one corner, barely taking up any space at all. It honestly feels like VW made the enclosure huge just to hide how tiny the actual driver is. And this thing is only 50 watts. The rest of the enclosure? Completely empty. Literally just a giant hollow plastic box with nothing inside.

It’s honestly hilarious in the worst way possible. And the speaker itself is super junk too — paper cone, bargain-bin garbage-tier stuff. I’m genuinely speechless. No wonder you can never hear anything from it inside the cabin.

This seriously lowered my opinion of Volkswagen. Their standards are way too low if they can call this a “Premium Audio System.” That name is basically a joke at this point. This “subwoofer”won’t cost them over $40. I’d much rather pay them a few hundred extra bucks for some speakers that’s at least somewhat decent.

Completed a BFI shift boot and knob replacement, but the boot was one of the most tedious processes. All the videos and documentation I found for my install were helpful, but I found some improvisation was required.

For instance, there's no section in the directions that includes chopping the boot down to size for a fold/crease free installation. On top of that the included tape is junk, I ended up buying a roll of doublesided 3M tape and cutting it to size.

So for those at there wanting to do it, caution, it's a slow tedious process. I found it worthwhile after seeing it installed, but I understand alot of the dialogue around skipping the boot replacement.

I was having issues with my alignment for about month. The car would drift and feel uneasy I bought new tires and knew it was time to get it sorted out. So I went to Firestone and they botched my alignment horribly the first time I took it 2 more times and they said the car had nothing wrong with the suspension. I finally just demanded my money back and took it to the VW dealer. They also did an inspection and found no suspension faults but that I have an uneven front right break pad wear 6/5. The car definitely feels better but I don’t know if it’s because I’m going crazy but very rarely it feels like it wants to drift again.

2021 GLI Autobahn

Been leaking coolant and i tried to take a look and it looked as if the coolant was leaking from somewhere above the oil pan. i checked every visible hose with out lifting or removing anything and i scanned the car and no codes came up.

So recently I installed new rims (FAST FC04 & before you start grilling me yes they’re on Hankooks) on my gli and I’ve noticed a couple things: these rims are 0.5” wider (8”) and offset is 40mm vs oem which is 49mm, so they sit more outwards and flush with the car. Before, the car had a wobbly/floating feeling to it but now i feel than even more, specially on high speeds it feels unstable and kinda not glued to the pavement + steering is much more sensitive to all the uneven spots of the road. Now my question is how much of these symptoms are due to tires being Hankook and how much are due to the tires sitting more outwards and flush?

After 9 months of driving rentals, insurance finally decided to write off my 40th anniversary.. I will always love this car but I had to go back to my roots.. always had trucks and this was my first kinda sporty car, so still sad to see it go but im now onto bigger and better things..

That said, some parts up for sale if anyone in the GTA is interested... MBRP cat back with carbon tips, 19" black pretoria wrapped in 255/30/r19 conti extreme contact, and a fitcamX dash cam.

Just curious everyone’s options are on the two especially for the 7.5s

It’s crazy that a set of headlights alone on the car next to mine costs just as much as my entire car insane stuff truly

Current setup:

• APR rear sway bar
• 034 subframe locking collar kit
• 034 dogbone insert
• BBS CH-R 19x8.5 ET35
• 235/35R19 summer tires
• Stock wheels with 225/45R18 winter tires
• Open air intake for sound

Note: the picture shows 235/40R19, but I switched to 235/35R19 due to rear fender rubbing with passengers.

Considering next:

• DieselGeek short shifter
• CTS Engine/transmission mounts
• Performance brake pads
• Lighter 18-inch wheels
• Stage 2: clutch, intercooler, downpipe

Main use is fun daily driving and mountain roads. What would you prioritize next for better feel, handling, and driving enjoyment?
