R350
For those with first hand knowledge replacing the rear bags
I have Arnott bags on order for the rears on my 2007 R350. I jacked up the car and took a wheel off to take a look before the bags arrive. I noticed that the line (drivers side) has a right angle bend just before going into the fitting on the original bag. I see many people have done this replacement in under an hour (both sides) but I have to ask. Am I going to have an issue with this right angle bent plastic line after I unscrew the OEM fitting? Or will the old fitting just slip of and the line (with right angle bend) just slide right into the new "push to connect" Arnott fitting?

No
Unscrew the brass fitting and let all the pressure bleed out of the system. The remove the brass fitting from the unit. Slit the brass fitting back and GENTLY remove the brass collet. It has a split that you part to remove it. If your fingernail won't work, use something plastic. You're screwed if you damage that air line. The collet fits in a small groove in the airline and that secures it to the new air spring.
Install the new air spring. Pull the little plastic pin from the brass fitting. Insert the plastic line and make sure it is seated. If you get pull the line out, its not seated. It takes a bit of pressure to seat it right and its at a odd position. Don't use the bend as a means to apply more pressure trying to seat it.

I just finished this job (2009 non-airmatic R350) and it went exactly as Arnott's You Tube video demonstrates. One of the quickest most straightforward auto repairs I've done in years. Now I just have to pray it was actually a leaky air spring that was causing the overnight sag. I guess I'll know tomorrow morning!
The air lines go back exactly as the previous poster described, just grip them with your finger past the bend and push them all the way in until the stop / seat.

I'm starting to really like my R500. Although it's got so many bells and whistles, I'm finding it easy to work on. Front brakes as easy as a GM or Ford. Oil change, OMG easy with the right tools. Filter replacement, a cake walk. My front shocks have 80k miles on them so going replace them soon and will install lowering coil springs in the process and will buy the adjustable rear links. Desperately trying decide on the wheels it want.
Gonna have the dealer flush the tranny and brake fluids, but otherwise a very DIY car.

The replacement went well. No issues other than me getting the jack stock under the car and thankfully the air bag lifted the car off the jack. Thanks to all for lending support.
