Going somewhere nice?
Best of luck with it. Those pipes look similar to the ones used on a 406 for A/C connections onto the compressor and some of the power steering pipework, (if memory serves, since I don't have one anymore).
My Citroen musings have taken a slightly different tack, the RT4/5 has started turning the display off & back on every 30 seconds or so, which I guess is indicative of a terminally ill hard disc. Initially I was thinking of replacing it with an aftermarket Android panel, but realised I'd loose the parking sensor functionality. Plan B was to get a 2nd hand unit from a slightly newer car, that would include Bluetooth, (which mine missed by about 2 months).
I had a towbar fitted on Wednesday, which I was pleased to see didn't interfere with the parking sensors, (cheapskate here refused the extra £60 or so for a removable one). Sure enough, come Friday afternoon the parking sensors 'discovered' the tow hitch and now spot it every time without fail, so I have to turn them off.....
Which brings me to Plan C revisit the aftermarket Android alternative.
