Not much you can do other than clean the coil with the car jacked up and wheel off and lube the coils will dry type silicon or Teflon spray. The coils on the top are what you wat to lube as these are the ones that touch each other when you lower the car. It helps for a month or so but it will come back.

Thanks for the info. Owning KW suspensions has been very fustrating for me.

On my last car, E46 330i, I had purchased a brand new set of V3's. After having the car corner balanced and aligned I found out that the rebound setting kept returning to the zero position. Turned out that KW had a bad run of struts. They offered abosolutely no compensation for me having to remove the suspension and send it in for repair. They could not even cover shipping. They returned it to me with the adjustments seized and I had to send it in again.

After getting that issue resolved I began to have issues with the swaybar endlinks wearing out very quickly(every 8-10k miles). After much back and foward I got that resolved.

Now with my 335i I had an issue with the tab on the strut that the endlink attaches to breaking off and bending. It has now happened to me 2 times. See the pics below.







Though they say they have had no issues using this suspension with the H&R sways they blamed it on that. I sent pics of the install that my shop did and they said all was fine though and I don't see how if the front bar I believe is only 1-2mm thicker than stock. Again, I had to pull the suspension twice to get it repaired. Owning KW's has been very expensive for me. Now it looks like there might be another inherent design flaw.
