I know there's a lot of concern over failed airmatic components - are there any




Just picked up the car and the struts seem fine. So I paid $400 for each strut with a lifetime warranty, and $450 for the labor (plus $93 x 2 for the ball joints). Dealer original quote was $3300 for the two struts and labor, so I am happy that I saved over a grand.
Based on one day of use so far with the new struts, and their customer service, I would recommend Arnott.

Maybe I can avoid messing with it completely and collapse the strut the same way Yaght Master did.

The mechanic at the dealership told me that without the Star Computer to compress the shock and needing to disconnect ball joints, it is a bear of a job for the home mechanic. I've removed engines and replaced clutches on past cars, and this is not an impossible DIY, but I ended up just being happy with the savings on the parts on this job.
Fyi, there is a good DIY set of instructions for the rear struts on Benzworld (without removing the rear axle), in case ever needed.
Good luck!

With all the info and pics it was not too hard a job as I thought.
WARNING to all who try it without Star/DAS, I tried and tried to do it like Yacht but could not get it to release. With my Star/DAS there is a simple button to release and fill the strut with air and with that it was cake in and out.
How Yacht got it to work I have no idea.....then again there has to be a reason he wears that Gold Rolie on his wrist when he works on cars.
Guy's a genius.

Thanks again YM!
I am back in business.
I just replaced my two front struts on my 2003 E500 with arnott struts. I live in Guam so there is no MB dealership here. There is a local shop that services MB's in the area and they installed my shocks. This was 3 weeks ago. Now I get the airmatic (vehicle with up arrow) visit workshop! warning on my display. The car is level and it responds to raising and lowering. I don't have STAR/DAS but I am considering getting it so that I can know whats going on with it. Did you guys reset the car after the struts were installed? If I dont have Star, how can I reset the computer? I have read that there is a secondary battery in the car that prevents you from powering the car down completely. Please help.
The only thing I would suggest is removing the plug connector and air supply tube from the top of the strut before taking off the three nuts that hold the strut to the shock tower unless you're supporting the a-arm with a jack. I thought the a-arm might drop slightly (which it did) so I diverted slightly from the instructions. I don't think it would have done much damage, but still I wanted to play on the safe side as far as this car is concerned.
The plastic clip still broke, but it has 90K on the clock and it's a Texas car so I guess with the many months of 100 degree baking, I can't fault Mercedes on that one.
I've worked on a few cars in my time and after being so happy working on my 95 Mustang GT because of it's simplicity, I implore Mercedes on their design. I remember making upgrades to my Camaro and working on just about anything on that car was difficult. I thought the Mercedes was going to be the same and I was pleasantly surprised. Kudos MB!

The caution here is that the up arrow warning comes on when the compressor runs too long. This could burn out the compressor.
Check after the car sits over night to see if any corner is lower than it should be and this might give you a clue as to where the leak is.
Best of luck I fully understand living on island problems for repairing equipement.




Thanks
update: Tried disconnecting battery several times and set to sport 2 mode, still hear NO air being released only hear and feel air coming from the airline; not the strut had it verified with another person.

1). I reaffirm all caution to use good Jack stands, jacks and chocks. SAFETY
2) unless u have some freakishly thin hand/arm you can kiss the wire clip goodbye. I use black wire ties to affix the assmbly I spent more time retrieving a dropped screwdriver in engine bowels than ding the active rest of the repair
3) For removal, I pulled 3wire control cable & air on top of strut & used Jack to compress the strut enough to get it over the lower arm
4) on install of new strut - spent over an hour trying to get the strut to release air but no luck. So went back and reread this thread then realized I never removed the shipping cap on the air input at the top of the strut. In my zeal to not hock up the air hose and prevent further extension - it wasn't obvious to me that the release was back into the air system. Once I removed the cap each cycle of power removal/add caused a 700 millisecond release of air. I had Jack on one of the flanges and continued to raise it as we cycled power. ( about 20 iterations did the trick). Piece of cake after that. Button it up and job almost all done
5) during first test fill. It took a couple of minutes to charge and raise it - I had to have car back down on the wheels ( but not to the full travel of the strut). Once it was up job was done.
thanks again for all the advice!
I replaced the left front strut on an E500 and here are the lessons learned. The E500's airmatic strut mounts over the drive shaft and connects to the control arm. Therefore the E500's have to clear the drive shaft AND the control arm where the AMG version has the driveshaft on the side and you only need to clear the control arm.
I ended up disconnecting the transverse control arm (upper control arm) where you have one nut holding it to the steering knuckle and the nut from the stabilizer bar. This allowed me to get the drive shaft down a few more inches though I was worried about damaging the drive shaft!

I do the alignment when I change tie rod ends, ball joints but not a strut.
But just my method only.
Hi All, could do with a bit of help here with compressing the new strutt on my W211 E55 AMG. I have connected the power to the strutt but not the airline and started car and put into sport 2 but the strutt remains at full extension. Regarding the above, where is the height sensor? I don't understand the laying across the engine bit.... Connecting/ disconnecting the battery isn't doing anything either so maybe my sensor doesn't think the car is high even though it's jacked up.
I have also tried to encourage it to compress with a jack but there's a lot of resistance and I don't want to damage the new strutt as well as it tends to slip towards the disc at an awkward angle also. Help please!!!!!
