ACS Springs popping noise
Anyone having ACS spring issues? At lower speeds when turning the wheels left or right you can hear popping noise like the spring is slightly moving inside the strut. I'm at the BMW dealership that installed it and they checked and said everything looks normal. There double checking it again looking at other stuff. Hopefully I'll get an answer.
ALSO: NIGHTVISION is not working properly. It's not flashing on the heads up or the screen as pedestrians are getting near. Also bottom left corner there is a yellow triangle/pedestrian with a slash mark that wont go away. I have the option checked marked for it detect pedestrian on the menu so that picture on the bottom left should not be there with that slash. Actually the picture on the bottom left should be with a check mark on it. |

Pm Nobleman. Him and his brother had some noises after getting their ACS springs installed and the shop ended up tightening something to fix it.

No noise from my ACS springs.
My Nightvision works fine, but can have problems with pedestrian detection in rain or fog when its warm outside, I think the temperature difference is to little in those conditions. |

Have never been to misery but is there an ACS certified mechanic.
I had my ACS spring installed here in Germany and have had no negative issues with them.

My ACS Springs were installed by the ACS USA Rep. in LA, CA and I have no adverse issues--only awesomeness so far!
My car is a 2012 550i M-Sport without ARS. Is your car a 535? (they have different springs). An "xi"? |

No the problem is not solved the noise is still there. The BMW service Manager is helping me out. They installed the springs so there waiting for a reply from AC Schnitzer USA and Germany to see what they need to do. It might be a defective spring. I dont know. Hopefully I'll hear something next week. I'll post back here once I know.

Doubt it's the spring being defective. It's a pretty simple part and I suspect something isn't tight enough causing the noise.
Normally the spring should be able to move/turn. Alan

Good to hear Alex. I am guessing its installer error at some point causing the noise because there are tons of cars with ACS springs without any issues here.
See you soon Alan

The springs should not make any noise: you are replacing one solid coil of metal with another. Some connection on the springs could be loose, but that would likely be a BIG noise. In addition, an overall stiffer ride could help you notice something else non-spring-related that is loose.
Good luck with your search! |

My car is a 2011 550 m sport. The BMW service manager from Plaza BMW where i got my springs installed emailed ACS USA and Germany. I'm still waiting. Once he gets a reply back I'll let you all know. Last edited by ausfahrt; 07-24-2012 at 11:06 PM.. |

I had ACS sprigs in my F10 550 m sport & had the exact same issue. CEC Wheels here in LA did the install. They couldn't figure it out. I eventually installed KW coil overs.

The install of the ACS Springs on my 2012 550i M-Sport was also done by CEC and so far--knock on wood--I do not hear any popping or other noises--just an awesomme ride. CEC is the West Coast ACS Distributor.

I suspect your issue is related to the thrust bearing on top of the shock being an issue. If the thrust bearing isn't tight enough or the dealer didn't put back the washers in the correct order it can cause the issue that you are experiencing. The dealer obviously doesn't want to check that area because it would require them to pull the entire front shock off the car again. I would bring it to another shop and let them get a go at it. If it turns out it was a faulty install then talk to your bmw dealer to have them reimburse you since they f'ed up and couldn't find it.
