I will have a few new things to learn from tomorrow.

I am puzzled. Onlne tutorials show an H8 removal from the rear port as fiddly as many others but not needing headlight removal .Greydog wrote: Sun Mar 23, 2025 9:16 am This is not one of BMW's best efforts in design and accessability
My E70 has halogen lights first winter I realised just how poor they can be I read many reports of E53's with halogen lights that were bad (both mine were Xenon) well BMW managed to somehow make the E70's worse !! My wifes Subaru Outback is Halogen lit and it is completely different ?
So first make sure the plastic lens's are clean a couple of hours with a lens polishing kit improved things (but not much) my next step change the lamps them selves. Here the fun begins to sensibly access the main and dip beam lamps you need to take off the front wheel and remove the front half of the wheel arch liner, now you can see and reach the two covers to get at the lamps. I upgraded to Osram Night Breaker +100% and can now see where I am going a really good improvement not as good as Xenon but good.
Now the really fun part I had a front parking light failure come up (the Halo light) to change that the whole headlamp needs removing !!! Wheel Off Liner out a few support braces to remove and unbolt the headlamp, you will need a good 1/4 drive set with a long 1/4 drive extension to reach 2 of the bolts took me 3 hrs to do both sides. The Halo's require a special BMW lamp at a really stupid BMW price so are now upgraded to LED (OK for MOT) while the Headlamps were out I changed the Indicator lamps as well didn't fancy doing it again soon.
