Not your seat is it? My seat creaks a fair amount sometimes, and, like you say, it's exactly that kind of "bed spring" noise, and doesn't sound like it's coming from outside the car. Another prime suspect would be the infamous clutch squeak, but it doesn't seem like you're changing gear in the video. Does it happen every time you pull away? It seems to be when you're already on the move, is it at the same speed everytime?

Suspension bushings adjusting? Might be worth giving the bushes a liberal spray with a lubricant and then see if it continues. This isn't a full fix but more of a diagnostic technique to help identify the cause.

Two thoughts on this A.) The engine bay isn't water tight and everything is designed to get wet B.) My car looks like a steam train when the wraps get wet and they puff. Personally I put something (usually a flattened piece of cardboard) under the bonnet when the car is outside and parked, and this is more to keep excess moisture off the wraps / air intake. I also have some rain guards, but TBH i found them a PITA to take off when I wanted to drive the car, and I always removed them when driving regardless of weather. Another factor on the rain-guards was they are excellent funnels for melted ice water when snow rests on them. My take, I don't worry about, if things break then it's a great excuse to upgrade them.

I'm perhaps the best or worst person to answer this haha. When i first got my car I originally fitted a vented Carbon bonnet and I dailied the car for about 18 months through all weather. During that time a bit of rain would just meant that the belt would slip for a few seconds when starting the car, no big deal really as i'd give it a rev and it would grab and be fine no problems! But then after I took my car off the road for 5 odd months, did a load of work on it and eventually started driving it again suddenly one of my idle pulleys on the belt system had a bearing failure! (the one directly under the intake) it's hard to say whether this was caused by the 18 odd months of rain etc potentially getting on to the belt & pulley but I've not done anything about it since replacing the pulley, then again I don't daily the car anymore. That's my experience atleast

What time stamp should we hear the noise? How old is the car and are there any mods? Try checking the exhaust or heat shields for rubbing. Are the diff bushings done up tight? Are the brake pads sticking at all? Is the squeak from the seat belt socket? I can’t really tell what the noise is so I’m just throwing some ideas out lol
