had my 2007 tdv8 on ramps today,only to discover fluid leaking from the arc unit.
it maybe just the o ring.fingers crossed.

im lead to believe its not possible to repair these units.

also do you have to take the unit off to fit o ring and can you change the fluid,if so how.

any tips and advice would be greatly appreciated

i have done a search on the topic but had a couple of questions that werent covered

thanks

Hi, I recently had mine in for a mot its the same year as yours, I took it to the local guy who failed it on the same leak, I then took it to the range rover specialist and asked them about it and they said they dont fail them on this leak because it is so common, They said keep it topped up and it will be ok...

mine passed mot ok
leak seems very small
it dosent drip on drive overnight.ifact no drips at all.
looks like light misting
just topped up maybe half a pint if that

What is the procedure for topping up? My rear one is slightly leaking I think
