After replacing the front struts for my 07 C5 MK2 with standard H3 suspension, the LDS fluide needs to be topped up. But the LDS fluide is no longer available in my country, so the mechanic recommended a DA fluide which is also orange color provided by TOTAL, sounds like a kind of power steering oil. So we added 2 litres to the tank to top up the tank. But I am still not quite sure if this fluide can be mixed with original LDS fluide although the specification of both fluides looks similar. Does anyone has any suggestions or experience about this? The orange DA fluide is also available on ebay. Thanks in advance. I needs to decide if the whole system needs to be flushed and replaced with new LDS again(LDS needs to be ordered overseas on ebay)? Will the new DA fluide do any harm to my seals and hoses on the car?

Hello all, I've owned a 07 MK2 C5 for one year. It's a hatchback with 2.0L petrol engine with 4AT. The front suspension refused to raise anymore recently so I turned to google and found this forum with plenty of helpful posts related to my problem. Finally I decided to try to switch the front struts, thankfully the suspension is OK now. I still have one silly question as a new owner. My car has only 4 spheres which may be a standard H3 system. After my car was parked overnight, its front will always sink 1-2cm, but will raise to normal height when it's unlocked. Is it normal or needs to be checked for problems? Thank you all for those helpful information shared with me.
