E350 s212 Hi all just after a little info from anyone who has done this or knows about it, I'm about to repair my air tube as one side strut keeps going down by half over night, when I investigated it I found under the compressor cover it had been repaired previously with two push fittings and I believe one of the fittings is leaking so I'm thinking to replace the whole tube as i traced this tube to the side that's deflating, I know that the tube is 4mm but I'm not sure of the putter diameter of the elbow needed to connect to the air strut and to the air regulator/ controller part I'm guessing you can't re use those parts and are they screww in parts ??

Very common. You can clamp a 4mm rubber hose over the top, but I would just buy the whole tube from mb! Only £30 + VAT.

There are screw on fittings on the air bag/valve block side, be careful with the airbag side, its metal into plastic. Don't forget the olive.
