I looked at the bottle at the Peugeot dealer and it didn't have the "electro-hydraulique" that I had seen online. So not being 1005 sure, I declined, went back to Toyota $49.50.  Wow.
Anyway it's done. Wish I had seen your post about eBay earlier... nvm.

I really wouldn't worry, that will be fine. Trust me I spent considerable time getting to that conclusion

Does anyone know off the top of their head how much PS fluid you need - capacity? 473ml enough or do you need more?

473 should be enough. I pulled the feed/return hoses from the reservoir to flush the old stuff and filled up with one 473ml bottle, bled the system, topped up and I probably had about 20ml left

I reckon my steering has improved since the flush and refill. I ran some anti-varnishing fluid through and drove it for a day, then drained it. The old fluid I was replacing did not look that bad. Amber, but perhaps it was more viscous than the correct stuff ?? But lots of constant correcting /wandering seems to have lessened. Still some tramlining, not related to PS.
