Btw it also confirms the compensation for aging... "Tolerance Adaptation The damper force is diminished as part of the operating time function. Diminishing damper forces are compensated by current (amperage) reductions which are calculated by the tolerance control. This also individually compensates for mechanical damper wear on each axle." ...as well as reset/clearing adaptations: "Notes on Service Mechanical wear causes the dampers to weaken over the service life, therefore a running time memory adapts the damper curves towards a harder setting (over time). Faulty dampers must be replaced together (in pairs) on a single axle. After a replacement, the running time memory for the front or rear axle must be reset with the BMW diagnostic equipment" Interestingly it speaks only about function over time rather than mileage. I would have thought mileage/driving have a greater impact than potentially parking over long time, good to know. Last edited by Helmsman; 03-01-2024 at 09:22 AM.. |

Yes there are interesting data referred to, if it only was possible to capture.... As mentioned I haven't seen any EDC "live data" on the couple of tools I happen to have. Also what I can see of BMWs own diagnose intructions/possibilities indicates there aren't much data being possible to accesse? There is a tool mentioned in the end for measuring on the EDC module, assumingly when it is taken out. Other than that damper needs to come out and be put in test bench? |

Technical Lit -- "Resetting" EDC Dampers due to Age
Quote:
Looks like the solenoid controls the valving of these dampers rather than through a fluid. M3SQRD So a couple of take-aways from the technical training regarding "age" and adaption reset:

I’m the one to blame. I specifically asked him if there was coding that had to be done when replacing edc dampers. I kept emphasizing “coding required” in all of my communication with him. I’d like to thank you and Helmsman again for setting me straight on the incorrect use of coding. I asked him if BMW required any test plans and/or procedures to be executed when replacing an edc damper. He said there was. Also, he has a copy of the vehicle dynamics document linked above as well as other training documents related to edc. So it was my continued incorrect use of coding that was the problem.

I want to replicate to verify that at least I'm getting a voltage difference between settings. To recap for others, when I test my EDC in ISTA (and even other scan tools), I see the following:

I did a new measure the other week, the fact that Protool and apparently ISTA doesn't show a difference is some other error but it doesn't affect that actual setting/current change. Let me know if more questions comes up! Edit: earlier thread with some further details: https://www.m3post.com/forums/showthread.php?t=1646115 Cheers Ps. Finally with new battery in place I plan to reach out to Bimmergeeks to get them to implement the EDC adaptation reset, which curently isn't there but Bimmers confirm the function is available. They need a car to add the feature so I'll plan to volonteer remotely. (tad strange that they don't have a chunk of mates/cars closer around in order to develop their product).
