I just realized last week that the flap was stuck half open again. Knowing that the springs were really strong in there, I was experimenting with replacement springs. Now I put another volvo thermostat and I changed the springs with softer ones. Now the thermostat is able to push against the spring easier to close the hot air port. Stainless steel springs seem to be softer in general. Let's get back to this in a few years

This is the part number I have 1S0075101 . It is for 2012-2016 VW Up! models. https://www.deutsche-parts.co.uk/mud-flap-1s0075101-new-genuine-part.html For VW Up! 2016+ models have bumper part 1S6807421AB and mud flaps 1S0075101A 2012-2016 models have bumper part number 1S6807421P and mud flaps 1S0075101 The 2012-2016 model bumpers do not have any attachment points for the mudflaps. That's why there are some plastic parts which should be clipped first. It is perhaps easy to install other than those plastic clips being so flimsy with so hard metal clips. Not a good combination. So VW fixed a bunch of problems after 2016 I should make a mental note to not buy a new VW vehicle before they make at least one facelift update to that model

@AGFalco thanks the kit came with 6 very hard metal clips and 2 very fragile plastic attachment parts. The attachment parts are hard plastic. One side has thin(~3mm) connection pieces. I don't think that the plastic will stay in place while hammering the metal pieces. It looks really fragile. On the thin side, there are holes where the clips go. So only the sides of the clips goes over it. I was just curious if anybody managed to install these without breaking them.

@AGFalco Thanks, but I was asking for installation photos of the mudflap clips on rear bumper. 😅

@freemansteve you mean the wheel arch liners, not the mud flaps 😅 @MickA I am curious about the plastic parts and clips for the rear mud flaps. Do you have any photo of how they are installed? Clips are really tight and instructions have a photo of a hammer 🔨 😅 it looks like the plastic piece are not study enough to hammer those metal clips. Very strange, a photo would be great.

@wino volvo thermostat solved the issue :) https://evren-yurtesen.blogspot.com/2020/11/golf-mk4-air-fillter-box-heated-air.html I still don't understand how you managed to change thermostat without removing the little black rectangular cover in the middle of the spring mechanism. Very strange stuff :)
