Mine has a coupler on the inside of the OSR wheel arch by the gear box, so I recently replaced the outer hard line from there outwards.

Suggestion
Well from what i've read now, steel pipes are inferior so perhaps I'll use copper/nickel as the permanent replacement.

I made mine using the self bending copper type with engine and gearbox still in, i then used proper brake line clips where possible to hold them firm along with the originals i could get to , pretty easy really, flew through mot no worries.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Good afternoon all,
It would appear I have a leak in my lines and the stains on the driveway appear to suggest it is somewhere in the rear (guess would be OSR).
I've read a few forums now suggesting the rear lines are a PITA to do due to being routed above the engine and hence require an engine drop to replace.
I have a local(ish) Porsche specialist (West London) who I haven't used before but was thinking of engaging to get this repaired.
I have two questions if you could help please:
1) what are my (alternative) options for repair and what's a rough order of magnitude in terms of expected costs? For example I have read about cunifer (sp?) lines being put in instead of OEM and routed below the engine until such time there is reason to drop it for some other job. The suggestion is these lines are much better than the SS OEM ones.
2) if the engine does end up being dropped, what other jobs would it be prudent to complete at the same time?
Car is a '98 tiptronic.
Thanks all!
I went with the Rocket Dog Racing braided lines as they can be threaded over the engine.

This is interesting as i am facing this. My understanding though is that braided hoses wont fit the "clamps" and therefore will be mobile and will fail an MOT/be unsafe. Other than braided hoses what do they offer that's different? Seems to me just offered for racing.
Also depends where it's leaking. Mine has a coupler on the inside of the OSR wheel arch by the gear box, so I recently replaced the outer hard line from there outwards. Someone has already put a copper line over the gearbox on mine.
I made mine using the self bending copper type with engine and gearbox still in, i then used proper brake line clips where possible to hold them firm along with the originals i could get to , pretty easy really, flew through mot no worries.
I would much rather have braided lines than copper (well copper is illegal, copper nickel is the thing) but every single indy i know said it is dangerous as braided hoses are too large to fit in the clips and therefore would be mobile = dangrous.
Then I found
this article about the latest copper/nickel pipes
which makes me feel a lot better about dropping the steel.
Wouldn’t you just cable tie the braided line to the existing pipe in all the places you could get access?
That should work until the day the engine is dropped and you can tidy up the job.
Good point. I don't know where the actual leak is happening just yet, but trying to equip myself with some background knowledge to form some options in preparedness for that discussion with the mechanic.
Do you know where the interface between the hard line and the flexi hose is?
