My E55 sits very slightly lower at the left rear position (wheel well). I am talking about left to right, as viewed from the rear.

When I measure the body ride height it shows about 3/4 " lower at the left rear wheel well than it does at the right.

The front of the car is level from left to right.

This rear difference exists no matter the suspension setting (comfort - 1 - 2) or the vehicle rising setting.

The Airmatic system does not lose pressure (sink) over time (weeks) so I do not think there is a leak anywhere or a bad air unit.

Are there calibrations for this left to right slant?

Or is there a sensor that controls this?

Thanks.

Do you have lowering links installed?

R.K.

 

No modifications on the suspension.
The car does have 19" AMG two-piece wheels.
And it only has 30K miles after all these years.

 

Wow 30k miles. Incredible. Very nice.

 

Did you buy the car new?

 

It was about 18 months old when I got it. It had 5K miles on it at that time.
The original owner bought a CLK 63 Black Series to replace it.
I got to see that CLK. Awesome car in black. WOW.

 

I believe the E55 only has 1 height sensor as the back, just as my CLS55.

Maybe a worn shock on the sagging side?

 

That is cool!

 

You are correct. L/R sensors in the front and one center sensor in the rear. Same with W211 wagons.

This would be my guess, too. It's time, even for well-maintained cars.

I have a 2003 and the original rear bags were still going strong until last winter, when after sitting for maybe 4 days, you can see it start to droop. Some people would be OK with it for a while, but I went ahead and switched them out for Arnott units.

 

They are also in my planning. Just did the rear bags and the compressor. The rear shocks arent that expensive (the fronts are!) and will be replaced in the near future (185k kms / 115k miles on my clock)

 

Yes, that could be it. The shocks are original.

 

I am going to go into that LR wheel well and check the sensor and the shock for leakage.
Since the air bag stays inflated (actually ALL the bags F and R) I am hoping that those are OK.
The car was aligned when I got now tires and it in on spec.
Perhaps I bent something along the way? (pothole)

 

Could also be, but a proper alignment shop would've noticed that straightaway.

I was just thinking that maybe the valve block could also play a role (one shock receiving more air than the other)?

 

Single air line goes from the compressor to the rear of the car where it splits to individual lines to the air springs. So you won't find an issue with an individual rear air spring at the valve block, but possibly at the split at the back of the car.

 

Thanks for all the tip Gents!

When I get to the bottom of this I will post the root cause and the repair information.

All the best... HEO

"Drive it like you stole it"

 

Ah yes, I totally forgot about that one. Its behind the rear differential (at least on my CLS)

 

It's the same on the W211 E63's. Typically, the airline doesn't go bad, unless their rubbing up against something overtime, which causes a leak.
