My 2015 insignia had a leak into the boot, it wasn't the vent because water doesn't flow up. There is a stupid hole in the side covered with tape. One is behind the fuse box in the boot which is easy to access, just fill the hole with mastic. The one on the other side is hidden behind sheet metal, you either cut a hole in the sheet metal or remove the pumper drill out the rivets holding the bumper clips on fill the hole, rivet the holders back on and your good to go. The vents he blocked up only let water in if you submerge the car or put a hose pipe directly on it
I have the leak you are on about and as you say it's not the vent... the vent in the video is letting in water because the hose is pushed upward by it. I'm not sure how to get at the hole on the right side and don't really want to remove the bumper. How far up from the bottom is the leaking hole? If I drill a hole with a cutter will I be able to see it?
Pretty sure that's what's causing mine, felt wet material in there and there was a black streak running down from it. I've blocked it up literally 10 minutes ago so hopefully that's it fixed 🤷🏻♂️ need some heavy rain to be sure as that's generally when it's happening most.
@@CarWaterLeaksFound well i 'gunked' the lower flaps and where the boot hinges sit as that is also a common fault. Washed car, still leake. So poured water over the jpints where the outter bumper meets the body work. Turns out thw waters coming through above the vents and not the vents itself. Still yet to fix. Pain in the back side these cars are. Just recently had a brake servo and 4 plugs fitted. 1700 quid. Brakes failed before xmas. Took 2 minths to source the servo!
I was just trying to figure out where my Opel Insignia 2011 was leaking from. It is most likely from the same place. In order to fix this do I need a new vent? Was wondering if fixing the issue would be considered expensive? Thanks for the video!
They also leak through the bracket either side where the bumper is mounted. It's the plastic bits that hold the bumper, they are riveted to the body. Common leak. Drill them out, sealer underneath and rivet them on again. You can tell it's leaking there if see water in the same area but not visibly coming through the vent.
The video is not wrong. The rear vent is leaking. When we take the bumper off to replace it, we will replace both, plus check and reseal all grommets and clips, including the hole sealed with tape that you mention.
@@CarWaterLeaksFound the vent is leaking because u are blasting a hose up at it. Road/ rain water doesn't flow up. U 100% need to remove the riveted on bumper bracket to expose that hole.
@@leecaddick8502 Water sprays up from the wheels - so it does flow up. As I said, once the bumper is off, all potential points of ingress are checked again. Then they are fixed, and then it's checked again. We are well aware of the holes that manufacturers seal with tape. We always remove them and seal them properly with plastic blanking plates. We also check the plastic clips, grommets for wiring, and welded seams.

I’m struggling to find a new replacement online.
Any help with a part number would be hugely appreciated.
Great video
Have a leak in drivers side of 2015 insignia elite, and very difficult to get source. Thanks for doing this video. Gives some insight where to try 😊
Can you tell me what moisture meter you use please.
Mine was leaking from rear lamps as washers worn out. I replaced with makeshift washers and leak stopped.
So how do u fix it? Need new vents??
Yep, replace the whole vent. Do both sides, they aren't expensive, but you do need to take the rear bumper off.

This video is wrong. The water will be getting in from a hole behind the bumper bracket that vauxhall seal from factory with a crap but of tape

The video is a little bit pointless without also showing how to prevent future water ingress. 😂
If you can't figure it out from this video, then you should probably leave it to a professional.
The video is wrong, the leak is from the joint between bumper and wing. Nothing wrong with the vent
