Sorry to revive this thread. On this diagram which is the pipe I need to take off to flush the PS fluid? Also should I get the clips too? Or am I better off just using a suction tool to replace fluid?
Thanks

When I did it I removed both hoses from the cooler and plugged hose 10 to stop the oil draining from the tank, then fitted a bit of hose to the tube stub on the cooler and put that into a bucket. and refitted temporarily the forward hose (18) back onto the cooler. the reason for the extra hassle is to flush the cooler as well.

Then got the wife to start and quickly stop the engine, refill the reservoir and repeat until I got nice clean oil out.

To get access you need to remove the hose in front of the cooler to tank hose (10) so buy 2 clips (9)

Ok thanks, you never mentioned the wife bit on your original post! So now I have to find a wife too including 2 clips:ROFL:

Delboy any special tools needed to remove the clips on pipe?
Cheers

Well 3 days into ownership and my car lost power steering, fluid filing the undertray. So I took it apart today and found no.18 (cooler to rack) spewing out fluid.

Can anyone confirm this is definitely no. 18 in ETKA and the ones in the pics being removed? Thanks

Yes it definitely was this hose. New one ordered and fitted. Was a PITA getting it out as I was being very careful. Wasn't too bad putting new one on and best of all the seller paid the bill.

Thanks to del ( and homer for pointing me to his thread) i changed ps pipe today as part of winter maintenance and it's exactly as per details (and wasn't difficult when i knew how to do it ) , I haven't bleed the system yet as I'm doing other works and can't start car but will do the flush ect in due course,I did find this non oem joint behind the heat shield ,(it wasn't leaking)

You're welcome. Looks like it had already failed in the past and someone f̶i̶x̶e̶d̶ bodged it

I am thrilled to join this club. My car took a #1 on the highway today. Sprayed the driver side wheel as well. The section behind the left fog light is all wet. I now have 2 A8s that cannot drive in my driveway :)
I will edit once I find the culprit.
