Looks like I'm going to have to replace the fronts soon. Adaptive suspension struts are not a cheap proposition. At least it looks like a fairly easy DIY.

How many miles have they lasted?

Only 49K miles. I have to double check, but I think it's the left front. If it's a slow leak and I can get it thru inspection in July, I might just let it go for a while. Hasn't affected performance at all. If I have to replace them, I'll do it myself in June. Best price so far is $636 each.

That's cheap and a wise way to go.
 
I happened to find a 2nd hand one on Ebay, from a salvage yard, for $199. Seller said it was from a car with 25k miles. Just to be sure I went to badvin.org and ran a report. The car has 50 k miles and the front left wheel had a pretty serious accident. Wheel was really battered. Can't imagine the strut is any good. More than likely, I will just buy a new set. But if I come across a deal for a front left with approx 40k to 50k miles, I might do that route.
 
Well just for the hell of it, I cleaned the oil from the strut and have since driven it about 250 miles. I'm not seeing any oil leakage so far. I wasn't planning on doing the job until June, so I'm just going to keep an eye on it till then. In my experience, I have seen garages squirt oil on shocks and tell their customers they found a leak. It's an con. Very good chance someone was trying to screw me. I'll report back in 3 months if I find it to be con job.
 
I think you will find that at 49k miles the strut will be shot. Best way to tell is to remove the strut from the car and then remove the spring. Try to compress the strut by had, most likely it will compress with very little resistance and won't come back up :o

These adaptive struts do not last long, mine were leaking oil and shot when I bought my zed at 42k miles.
 
Does anyone have brand suggestions for purchasing non OEM (too expensive) adaptive suspension front struts for 2011 E89 sDrive30i? Both front struts are leaking and shot at 45,000 miles. Thanks.

These look very much like the Chinese adaptive struts with the silver cap. I replaced mine with BMW struts, very happy I did.
