Hey guys, new to the forum but i'm a long time lurker! Just today on my ride home from lunch I noticed that my car (2005 E500 Sport) was riding really stiff and the "visit workshop" light popped up. It was almost like it was in sport 2 but it wasn't. So when I got home I plugged in my MB V2.0 and checked the suspension codes and I had a code 5193; Power Supply Sensors: Short Circuit to ground. Not only does it ride stiff but the lift button doesn't turn the compressor on, and when I checked the pressure switch value it stated it was at 509 psi. Also none of the level sensors read voltage, they all read 0 now. Last week I had a 5132; B22/8 (left front level sensor): signal failure and I could see from the live stream that the sensor (signal two left front) was clearly less voltage (0.16V) than the others (signal one left front 2.22V and both right front signals were around 2.25V). Fast forward a couple days and I check it again, all good, all sensors are reading around 2.25V until today. The only thing I did when all this started about a week or so ago was go to the car wash and spray out all the snow and ice up in the wheel wells. Maybe water from the pressure washer got into the sensor and started havoc or the sensor (if its faulty) just finally crapped out and its nothing to do with the carwash. Regardless I need to get this fixed! Any insight would be greatly appreciated!!!!

Just a update for anyone who might have this problem in the future. I ordered a ride height sensor from www.CarID.com for around $65. Upon receiving it I compared the two and the new one had all the markings removed with a pencil grinder or dremel type tool. I installed it and the suspension started working again (soft ride). I now had signal one again but still had 0V on signal two according to my MB V2.0. I scheduled a appointment with the local shop to have them look at it and basically what they told me is that the ground and power checked out fine and that it was a faulty sensor still. He told me that the two signals needed to total 5V between them. The even weirder thing was that the voltages they got off the signals with their scanner were way different than the voltages my scanner was reading. The independent shop quoted me $230 ($150 part, $80 labor) to replace the sensor. Just out of curiosity I stopped into the MB dealer and the part was $210 through them. So basically if I have the independent shop do the repair it would cost me $20 more than if I bought the part from MB and did it myself. I'm going to do some searching to see if I can find a MB part online for cheaper or i'll see if the independent shop will sell me the part. It's a pretty straight forward job with the exception of the plug being tight on the sensor and was a pain to get undone on mine, more than likely the original 14 year old unit and its never been unplugged. If I remember correctly I used a 10mm ratchet wrench to remove the two nuts that hold the bracket to the body, 8mm socket to remove the two bolts that hold the sensor to the bracket, and then I used a thin ignition wrench to hold the stud that goes through the sensor arm (to keep it from spinning) and I think a 8mm on the nut.
Front left, right, and rear level sensor = part # 0105427617.
Thank you sir, that matches the part number on the back of my OEM sensor (010 542 76 17). It doesn't match the part number of the sensor I bought from CarID, or atleast what they claim it is on the receipt since all the markings are scratched out, the receipt says the part # is one digit off (010 542 77 17). Maybe this explains why it isn't reading the second signal? FCP Euro carries the OEM part number for around $63 so it looks like i'll try them.
OEM part on the left, CarID part on the right.
Receipt shows the part number being one digit off from OEM, not sure what the difference in the parts is though.
any resolve? replaced the front left height sensor and now the height values are OK but it has the same symptoms listed in this post, low voltage for left front sensor...

Hello. I’m having this same issue with Airmatic fault 5193. I have zero voltage from all sensors. Did you resolve your problem? If so, what finally fixed it?

I have not fixed my issue or looked into it further. I have all of my sensor voltages besides ONE of the two readings from the front left sensor. The wiring is ok so I’m leaning towards a malfunctioning airmatic ecu

Guys
I have the same issue. There are two sensors available that look identical for this car.
on websites like autohusaz they say they fit and one for without 4matic.
Get the other sensor with the part number 7617 t the end. You will get your both voltage signals.

Do you know if this is universal to all Airmatic? I have a GL350 (X164). And how do you know which sensor is bad, or did you do all three?

When you scan with Star diagnostics or a decent scanner, it will tell u front right or left or the rear.
on most cars rear only has one.
On w211 the front and rear sensors are the same.
But you must just get the correct part number and then your car will have three of those sensors.
My w211 E55 has the 7617 not the 7717.
2006 CLS55 IWC, 2003 Black E55 designo interior, 2005 White designo E55
Correct part number for w211 e55 c is 0105427617
Not the 7717 part! Ive ordered three because a Mercedes main dealer website incorrectly hass the 0105427617 as for 4matic only, that is incorrect!
0105427617 is not for 4matic, it is the original part that is on all the Rear wheel drive w211
Hope this helps someone save a couple of days waiting for parts.

that makes sense, it sounds like I was sold an incorrect level sensor as well
Definitely to save time
ensure u either look at the one on the car or call the dealer to confirm the part number by using your VIN.
Ive waste d 2 weekend now because got the wrong 7717 part.
annoyingly the sensor from fcpeuro likely has the part number scratched out, they do that on OEM conductor plates I’ve seen it’s a very strange practice and annoying to cross reference parts upon examination at a later date. I will see if they will send me the correct sensor since I’m sure I used their “matching” system by entering my make/model and body style

Yes its amazing how they even know which sensor they send.
I've been sent three 7717 sensors, with no part numbers, just placed in plastic packaging. So for all I know they could put the wrong one in the wrong bag.
why not even put the VNE part number on it.
I know they can't put the mercedes number.
Honestly its ridiculous and if Mercedes were charging a little less than theuir close to 200 dollars per sensos then i would just buy it from them.
but right now these VNE oem sensors are like 70% cheaper than dealer.
so at the end of the day, after all this inconvenience, I guess I'm still happier to pay 7o% less.
Hope this thread helps others.

Do you have a specific website you ordered the correct sensor from?
The previous poster was correct. I spoke with fcpeuro about returning the incorrect sensor and ordered the 7617 sensor. Installed the sensor and finally was able to perform a level calibration for the first time of about two years of ownership. Before calibration the front sat a bit too high. I will have to fix my low-hanging exhaust to lower the car even further. But not bad for a $500 car

hi I ordered it from ROCKAUTO.COM
For this part and Arnott struts, they have the best price.
I ordered a spare one to keep just in case. Because I called 3 dealers and I was quoted almost 220 plus tax! How does 59 plus tax sound from rockauto.com?
:-)
Make sure you order the VNE brand, it is OEM made in Germany.
