Couple of questions- differences

Hi all

Been under the front of the new Z4 for a good look and some quick and easy maintenance (ARB bushes, drop links and brake pads)

Noticed these and should have taken pics- but someone will know what I'm talking about

Off side wishbone had a link to a device i've not seen before- assuming it is a levelling device of some sort for Xenons (???)
Near side, under the radiator, there was an aluminium block with inputs and returns pipes- deffo didn't have this on the last Z4 which was manual- is it to do with the auto box?

Just curious more than anything else as specifically different to the last car!

Cheers

Stuart

Hi mate,
Wifey's 2.5i auto has the Xenons and yes, a levelling lever thing-ma-bob on the OSF wishbone.
Hers also has the big ally block. I think it's to do with cooling the transmission oil??
Hadn't realised yours is an auto. In that case, referring back to the cooling thermostat I told you about that the expansion tank sits over, I'm pretty sure yours will have that too. You can either keep your fingers crossed that it stays together, or get one to hand and replace it when you swap the expansion tank.
As I said, mine launched itself past by ear as I removed the bottle. It seems the locating lugs get weak and the BF Spring inside distributes the innards to the four winds.

This is the one I got:

Ah I saw that when i was searching 'thermostats' that fitted the new one!

Thank you- worth getting one just in case!

I was surprised how fragile looking the xenon armature looked, and rubbish placement to get to the drop links!

I would tbh.
If you look at the photo of it you can see a slot in the middle with a lug in it. Same on the other side.
The two halves 'bayonet' together. On mine, one lug was already missing it seems, and the other snapped once the bottle was no longer holding it in place.

what does it do?

What? when it's not trying to take your eye out?

Not entirely sure, but I'd guess it somehow opens and closes to use coolant to control the transmission oil temperature within that ally block?

Makes sense

Ordered- marathon pending for next weekend weather dependent so it will be here for that!
