Looking at the state of some people's screens on a frosty misty morning as drive to work/school run that's more than good enough to see out of !
Just like driving a tank ;).

Let me see If I can explain myself thinking.


When you top it up/fill it you do so with no pressure in the system πŸ‘.
When you put the cap on you are not trapping any pressureπŸ‘.

Now if you put the cap on with it warm/hot, cos you were running it and "burping" it then as it cools it will cause a small vacumn, so you would get a hiss posibbly when you next remove it "cold" not pressureπŸ‘.

If you top up to the correct level you have an air space (lets say X).
Now when you run it up to correct temps because of the air space you have "X" it will allow the system to reach a pressure of (lets say Y).
Making sence sofar?

So at "Y" pressure you lose fluid somewhere, till you get to the lower level that yours sits at.
It will sit at that lower level because now "X" is +1.
Now when the expansion of the coolant occurs due to heat it has more air space to pressure so "Y" is -1.
So the pressure now is slightly less and not enough to overcome a leaking connection somewhere.

How was the Science lesson?:DπŸ€”.

So you're thinking head gasket?!
 
I did read somewhere about the idea of the coolant tank being split past way up, coolant drops to that level and no further. I don't think that's the case here though. When i checked the other day and took the cap off the whole area looked dry and the level was up.
I think it's just the cap that's dead.. still not ordered a new one πŸ€”πŸ˜₯πŸ™„
 
P38, front side wing indicator lens was cracked and looked a bit shabby. Got a used unit that had green gunk inside it, as I was trying to wash it out the clear lens dropped off the unit. Removing and Replacing the whole unit , which is what is supposed to happen, involves removing the inner wheel arch liner to compress the fingers of the lamp unit to push it out, pita.
So I pinged the old cracked manky lens off which was surprisingly easy, it's assembled with what looks like a sticky double sided foam gasket, long past its best hence the manky gets in. Stuck the now spotless uncracked clear lens onto the cleaned up housing with a carefully applied bit of clear silicone.
No disassembly needed.
My cdl decided not to work off the fob but did with the key, fob led worked so came in and did a search on here and found an old post from me with the same symptoms a while back which I forgot about!
I sorted it then by luck if anything by turning the key back and forth in the lock and pressing the fob buttons in no particular order and it started working again. So I tried the same again but a bit more scientifically, locked with the key then pressed lock, unlocked with the key and pressed unlock and it all worked off the fob again. I had disconnected the battery earlier to change the steering wheel which normally has no effect on anything ,even the original alpine radio doesn't need a code, I just have to reset all the windows and sunroof and time clock.
