Mk5 General Area / Speed-dependent differential noise (JCR trans)
« Last post by Hobo Ben on Yesterday at 01:22:39 pm »Hi All,
I have a 2008 Golf V Variant with the 1.9 PD TDI BXE engine and a 5-speed manual JCR transmission. The car has approximately 372,000 km on it.
Last year, it suddenly developed a loud humming/growling/whining noise above 70 km/h, which gets progressively louder as speed increases. [Here's a video (https://www.youtube.com/shorts/4vbNl6U1WMU), you might be able to hear it there.] At first, I suspected a wheel bearing issue, but I ruled that out since the noise doesn’t change during cornering or under side load.
I’m starting to think it could be related to the differential or an output shaft bearing. When the noise appears, nothing seems to affect it, not changing gears, not pressing the clutch, not side loads, not even different tires. The tone is only dependent on vehicle speed.
I replaced the transmission fluid, but that didn’t make any difference. However, I noticed that the noise only becomes noticeable once the transmission has warmed up, usually after about 10 minutes of driving.
I’ve driven around 10,000 km with the issue so far, and it hasn’t caused any additional problems.
I’m currently trying to save money as we’re planning to buy our first home, and I’m also unsure how long I’ll keep this car due to rust issues. Still, I’d like it to remain reliable and not leave me stranded somewhere, or worse, lock the wheel at highway speeds.
Has anyone experienced something similar? If so, how long were you able to drive the car before addressing the issue?
Thanks in advance.

Mk5 General Area / How Much Does Wheel and Tyre Affect Ride Comfort
« Last post by lazy on Yesterday at 01:04:16 pm »I'm wondering if anyone has any experience going from 17's to 18's, and touring tyres to sports tyres.
I'm probably due a new set of tyres this year and I think the 18 Monzas would look good but I don't want to sacrifice ride comfort really so I'm wondering if it's a big difference going from 17's to 18's.
Also I'm wondering if there's a big difference in comfort between tyre styles for example Continental Premium Contact versus Sport Contact.
Any input would be greatly received.

Mk5 General Area / This just fell off of my 2007 mk5 FSI
« Last post by dadawg22 on February 21, 2026, 11:33:57 pm »for some context, yesterday my car began to make a pretty audible scraping noise while moving - sounded like sheet metal being rubbed against, and that day the wheels seemed "stuck" when I initially backed it out of the garage. led me to suspect a seized caliper.
began investigating with the rear passenger side brake when I noticed this thing dangling in the air, I poked it and it fell off. I suspect it's just holding a cable in place?
the rear caliper is actually scraping too so that's gonna be a fun job, but what exactly is this pin and will I be able to drive to the parts store with it missing? I have not been able to determine where it fits after having jacked the vehicle up.

Mk5 General Area / Re: What did you and your MKV do today?
« Last post by mjmallia on February 20, 2026, 08:04:56 am »My GTI has the 10 speaker audio system not the usual 8, and the drivers side Mid was not always working unless the volume was cranked up.....then it came alive.
It was not the wiring to the door as that must be fine as the tweeter and bass speakers were fine.
The Mid speaker was fine as all were replaced a couple of years ago so as a last resort I decided to swap out the factory crossover (the 10 wire, triangular module that the door have) and it worked
I have full sound now and it also sounds better, so the original must have failed.
