D2 S8 Power Steering Fluid (help needed urgently)

I think the 3 hoses in question all run from the pump to the steering rack (or maybe it's just 2 of them, I'm not sure). I think part of the problem is that they pass through (or very near) the n/s wheel arch so they're a little exposed to the weather and anything the wheel can throw at them. It was under the wheel arch area where my leak started.

Think that might be the one I had to get made up from Pirtek, don't know how much it was yet.......

Well I got 'lucky', the high pressure delivery pipe I need is 'only' £289 + VAT from Germany.
The dealer was kind to me and is giving me a 10% discount.
I may as well get the cheaper return pipe which is only £78.

All in all £400 for two pipes! They better last another 16 years!

Does anyone have the three part numbers for these pipes? If they are already scarce, it may be worth trying to track some down before they all disappear, as others have mentioned. That way we can all add to our stockpile of 'spares'.

4D0422887K - supply hose from reservoir to pump. Think this is NLA already
4D2422893D - pressure hose front half (one of the expensive ones)
4D2422893M - pressure hose rear half (the other expensive one)
4D2422891C - return line to cooler (I think Mark had the last of these)
4D0422891C - return from cooler to reservoir (just a plain hose)

These are all for V8s btw. V6s are different. The two pressure hoses are the ones to get as the union between the two is in the wheel well and rusts out. These are the complicated ones which are non-trivial to replicate. The pump supply and the return hoses can be recovered by crimping new hose on old unions.

Wow! Is there anything you don't know about these cars MJ?

Brilliant MJ.

Just realised I got a number wrong - pressure hose rear half is 4D2422893M

Tintin, MJ is fallable, after all!

Everyone is entitled to the odd mistake, once in a while. Just glad you're here to help the rest of us.

Just been having alook at my PS hoses to assess their state given MJ's comments about the corrosion issues and their exposure in the wheel arch area. Mine appear in good shape with no corrosion on the sleeve joints/crimps and the rubber appears good too. As a help to others identifying the hoses I produced the diagram below from the on-line parts app suitably annotated with MJs parts ID. (excuse the poor colouring in )

Nicely done David!

Except for the colouring in of course. Didn't they teach you how to keep inside the lines at school?
