Dynamic Suspension Strut Fail

I just picked up my E550 from the shop after giving them $1700 to replace a badly leaking electronic strut. Just the part was $1200. This happened after only 60K miles and I looked at the other one and it is also starting to leak!

This is unheard of in my experience. I have an XKR with electronic shocks that is at the same mileage and 13 years old and it has never had a suspension problem.

Keep an eye on your struts.

Hi Oldmots,

I have a c207 e350 in Brazil and got the same this week. Car has only 62.000km and left strut start leaking this week. I found your post searching how to disable this ARS without getting fault codes. Will create a new thread for it.

Did you replaced yours with the same supplier? Are they monroes A2073231100/1200 too?


Thanks

The shop replaced the part with the identical part. I guess if it lasts 8 years, it'll just have to do. I'm not pleased at the prospect of replacing the other one soon.

This issue of complex suspension systems reminds me of my Jaguar XJ with active air suspension. It was also a nightmare of concern as to when the thing would be sitting on the ground in the morning. I got tired of dealing with it and sold the car.

I just wish car companies would just give up on fancy suspension systems and just make things that hold together better. I know the vehicle dynamics system was an option, but you never think of the cost to repair them when ordering options, you just have visons of being Fangio tearing around the corner to the supermarket!

Could be a leaking valve block you can't blame the strut without checking.

I know a leaking strut when I see it, the upper spring mount is covered with oil and it is running all the way down the strut. The only valve in this strut is internal and is activated by the dynamic suspension system.

Did they replace both struts or only one? What about the rears?

At $1700 each , I replaced only the badly leaking one.

The other one has started to leak but it is not bad enough to replace quite yet. I hope I can go a year before replacing that one.

The shop did not mention the rears so I will try not to worry about them.
