Adaptive Drive suspension replacement questions
Do I have to replace with OEM adaptive drive shocks? If not, what would some options be? If so, where would/could be the cheaper price options be? https://www.mdecoder.com/decode/l310495 Thanks in advance for any help! |

I just went thru this last month; '07 3.0si with Adaptive drive(Electronic Dampening Control). "EDC malfunction" message started coming on intermittently at about 115-120K miles; then on all the time. Car drove like the struts were completely shot, since each shock's fluid valves default to the "open" position. Front AD struts are about $800ea, and rear about $500ea just for the shocks (thru "yourBMWparts.com"). No rears anywhere in the CONUS, and about a 2 month wait to get them from Germany... So, about $2800 wholesale just for parts. Then add $400 for an AD wheel alignment...
I'm getting ready to sell the vehicle; so, no way I was dropping $3300 on shock swap for a $6000 car... Especially after dropping $2500 earlier this year on other maintenance; (H2O pump, AC compressor, front crank seal, DISA valves, fluid leaks, etc)... I ordered non AD Bilsteins for all 4 corners, new bumpers and cushions, and had to replace front springs since one had broken in the strut. Replaced them all without any issues. Will always get the "EDC Malf" on startup, but the car rides and handles much better. I don't believe it can be coded out, but frankly IDC... As a note: the front and rear AD sway bars will not work as designed, since the AD system completely disables itself if any part is inoperative. The E60 series has standard struts with AD swaybars, and works fine, but the E70 is all tied together (according to the local BMW stealer). Bilsteins: $670 Cushions, bumpers, and hardware: $130 Used springs: $125/pr Total: less than $1000 If you plan on keeping the car long term, and go the standard shock route; you may want to consider replacing the AD swaybars (and mounts) with standard ones from a wrecked E70. It will also require plugging the hydraulic lines from the PS pump that supply fluid to the AD sway bars... Good luck whichever path you take. |

Say to read someone will pick up a used car and have to report "yeah the prior owner hacked that all out".... There are no aftermarket or OEM replacements that I know of. Only option is OE BMW parts. (or used) When I face this, I will try and find someone to rebuild mine. Probably need to ship them to a company that works on race cars, a real shock specialist. Finally, I recall back in the day the early 1990-92 Q45s with the adaptive suspension...people would hack them up, then finally the car would arrive to a true nut who would restore them. Sigh. |

Ard, I would think you might enjoy a rebuild project like that and could handle it. I’m not looking forward to the same dilemma. I’m at 160,000 and counting. What’s the failure rate on the AD struts? Have these struts been stressed less than non AD struts due to their design?

Lol
It isn't. Unless you are talking to a shyster dealer/shop looking for excuses to $crew you. Then there is the whole 'I wanna get rid of it, so not really gonna be honest nor push for anything thaty doesn't support what I want' |

It’s funny. I have a shop near me in Charleston (supposedly reputable) that charges extra for vehicles with adaptive drive. Needless to say I did not use them. I think the price was $130 without adaptive and $170 with.

A friend owns a tire store. BMWs have all sorts of 'special pricing'.

I also asked him if the alignment values were different for AD vs. non-AD; and he said yes. I can give you the shop's name and number; and you can throw your snark and condescension directly at them, if you'd like... Last edited by n64456; 08-19-2019 at 07:28 PM. |

That shop lied to you one on one...posting to the public as if it were a fact was your call. Happens. In the M world it is common for service salesmen to wind up owners about how 'special' their cars are, as a way to extract $$$. Just beware. I wouldn't trust the guys you spoke with... |
