Mk5 General Area / Re: BOV- Bad for car?

« Last post by GVK on February 06, 2026, 05:28:38 pm »

Because the car runs a MAF sensor based fuelling system, any unmetered air from an atmospheric BOV will upset the fuelling, could cause lumpy running and stalling.

Well done.  The plastic pipes and a load of heat cycles and age makes them brittle

Common issue on all Golfs and other models is the rear pressure vents that are on either side of the car behind the rear bumper.  Just done my wife's Mk5 and will do my GTI soon also.  Bumper off, vents removed and sponge seal binned while the vent groove is cleaned out......then used a decent silicon to seal and bond vent to car.  No more leaks and far less condensation on windscreen too, but interior is still slowly drying out, so can see that only improve with time.

Early/late warning signs it has failed or failing is the amount of condensation on the inside of the windscreen

Image is for example

Mk5 General Area / Spotted a Mk5 or Something Else Interesting While You Were Out?

Have you been out recently and noticed a Mk5 or another eye-catching car on the road or parked somewhere unexpected? Share what you saw, where you spotted it, and what made it stand out—whether it was a clean original example, a rare spec, or just something unusual that caught your attention.

Noticed a burning brake smell couple nights ago, passenger wheel was hot to the touch. Driver's side wheel was about 20 degrees on the laser gun, pass. side was over 100 degrees C! New front left caliper fitted from local motor factors (Apec) about £70. Sorted.

Just an intermittent P2015 code to fix now , Inlet manifold runner flaps fault putting the EML on, seen online can get a bracket machined to stop the inlet manifold runner motor over extending giving implausible voltage error.

Performance Modifications / Stuck Engine Cover Mounts - Cold Air Intake

« Last post by dadawg22 on February 05, 2026, 11:19:29 am »

Hi all, I'm trying to install a CAE into my FSI engine MK5.
I'm unable to remove the rear airbox/engine cover mounting studs WHT000898A near the firewall, using a deep 24mm socket just causes both to spin in place - plastic internals might have stripped.

Has anyone been able to resolve this issue without resorting to destructive methods? I don't really have any concrete strategies as to how I'll get those mounts out.

I'd appreciated any advice, I'm relatively inexperienced with working on cars.
