Pipe repair on self-levelling suspension
I have just got under my 250td and discovered that the steel pipe that winds its way around the rear suspension and feeds the oil to the self-levelling suspension control system has rusted away and burst.
I doubt very much it is possible (i may be wrong?) to thread a new one on because of the contortions this one has had to endure to avoid the suspension. so presuming i am right, how does one repair this: are there copper replacements that can be bent appropriately, or can one do with a rubber replacement? are these parts available or do they have to be made up with special tools to attach the appropriate nuts and threads etc. many thanks stumbler

You may be able to find pre-made lengths of brake/hydraulic line at a parts store. Or adaptor fittings that will allow the use SAE parts and flared fitting. The replacement line need not follow the old line; it can be fitted in a more convenient routing.
The dealer might have a good price on replacement parts so check that first.

Like Chas said, you can buy standard lengths from parts stores and bend them yourself. If you do, buy the spring tool for bending this stuff. It fits over the piping and prevents the pipe from crimping during a bend. A second alternative is to fill the pipe with fine sand before bending. THe sand supports the pipe during bending. Just make sure that it is thoroughly cleaned prior to putting it on your system.

Had another session underneath the car, and it seems that my problem is going to be how to get the old pipe off? everything is rusted, both ends. i have tried graspers, WD40, heat, but i can see this is where the real problem is going to lie, not the actual replacement.
I spoke to a mechanic today, and he just let out a big sigh and said 'that is the problem with them!', when i told him the situation!!! I can see everything being replaced as a more cost effective alternative to just replacing one twenty-inch pipe! I'll have another go today and see if a bit more heat and oil can make a difference. many thanks
