For £12 you may as well give that a go yes.birdy_z4 wrote: ↑Tue Nov 14, 2023 4:45 pmenuff_zed wrote: ↑Tue Nov 14, 2023 2:54 pmhttps://www.mlperformance.co.uk/product ... tor-inc-z4
Did you try simply reseating it?
Or the other option of taking that seal out, measuring it, and trying to buy just a new seal?
I cleaned the area down and gently wiggled the plastic connector before the test and it was not leaking. I've ordered a second hand (only £12) of a 2012 model so I can take the seal from this without spilling out the antifreeze to see what the seal is.
When this turns up I am going to use it to measure the seal and use this hose as plug when I disconnect the one on the car to prevent the antifreeze going everywhere (hopefully) method in my madness I think.
There is a steady pressuised stream/jet going pack to the filler tank so pretty sure it is not an issue with the water pump or thermostat
Then possibly order two new seasls, refurbish the second pipe and you'll get at least your money back.
One point to note: you may find the company sells seals in minimum quantities. In which case, pretty sure you'll find home for ther others on here.
