My car is presently in at the dealers (UK) with a chassis malfunction fault which keeps coming up. When it does, the first thing you can notice is suspension goes to a very firm setting, steering becomes heavier, rearview cam doesn't work. Its also impossible to switch or adjust the steering settings or suspension settings. Checking through fault codes its saying something like an EDC short circuit. Anyway, I dropped the car off yesterday morning, by lunchtime I had a short video message showing me the problem. One half of the fuse box isn't powering up. They've ordered a new fuse box as its a complete unit, and it will be fitted today. Personally i'm not convinced its the fuse box but who knows. Funny they found the fault so fast and also had one for delivery next day. Seems suspicious, as if this may be a common issue???
Anyway, I did get a loaner brand new M5 for the day yesterday but had to return it as it was a sales demo. They gave me another M4 until my car is fixed. They also tried to get me to part exchange into an M4 CS. I'll let you know what the result is. ps, the M5 is an absolutely awesome machine. The engine is so powerful and smooth, car is super quiet compared to the M4, it handles like its on rails with the 4wd system. Pity they cant transplant the M5 drivetrain and engine into an M4. The M5 is a boring looking car but probably one of, if not THE best car i've ever driven, from a drivers perspective.

Error Code Fixed by Replacing EDC Sensor and Cable - DIY
Hey guys,
I just had this issue and with the help from this thread and others, was luckily able to fix it and make the error code go away. For those of us out of warranty it was about an hour DIY and $155 in parts, pretty easy to do once you jack up the side enough to take the wheel off. The car is non-ZCP 6spd with EDC and has 47,000 miles on it and all of a sudden it started throwing the Chassis Malfunction error, turning the suspension ultra-firm and not allowing Sport settings. I used my Bootmod3 app to diagnose the system and got this code: Vertical Dynamics Control (Suspension) VDC1 482941 Rad acceleration sensor - front left - sensor 1 - below threshold In reading some other posts it seemed like a good idea to spend a few bucks to also replace the cable, so I found BMW Northwest as the cheapest online - Part numbers: 37156871465 Accelerating sensor (same part for both left and right) 31307850609 Cable, wheel acceleration sensor https://parts.bmwnorthwest.com/p/BMW...156871465.html https://parts.bmwnorthwest.com/p/BMW...307850609.html Install: Take front wheel off, take cover off the front inner wheel well, unhook the old cable and install the new one, unscrew the old sensor and install new one (one screw), reverse the above. Again it took only an hour or so. I live in an apartment with no garage or tools so I found a local DIY garage with all the tools for $40 per hour and it was a lot of fun! I attached some pictures but it's pretty straightforward. Have been driving around for a couple days now with no error, where before it would throw the error every time I turned on the car. Cheers!

have the same problem since a few days
but in my case it is the rear left wheel i can't find a acceleration sensor for the rear axle only the front axle has an acceleration sensor Vertical Dynamics Control (Suspension) VDC1 482948 Rad acceleration sensor - rear left - sensor 3 - above threshold 482949 Rad acceleration sensor - rear left - sensor 3 - below threshold 48294B Rad acceleration sensor - rear left - sensor 3 - value implausibly 482969 Rad acceleration sensor - rear left - sensor 3 - supply undervoltage it happened in december first time, on a rainy day, appeared a few days and than it was gone but this week it was rainy again and the warning pops up again should it be enough to change the acceleration sensor cable with the part number 31307850599? or do I need the acceleration sensor too? where can I find it for the rear? thanks a lot |

I'm having the same problem... the dealer replaced the accelerating sensor BM37-15-6-871-465 and it seemed to fix the issue. Prior to this it was constant... I now only get the error when backing up and turning all the way (locked) to the right.
I am scheduled to take back in today... I hope they don't blame the H&R suspension. |

bump.
can anyone confirm that replacing the EDC sensor and cable solves the “482941 - Rad Acceleration Sensor - below threshold” code? i’ve been getting this code every day and it’s irritating that my suspension goes to straight Sport+ mode on these NYC roads.

I just replaced my front left rad acc sensor too and its still throwing the chassis malfunction. I installed the part, did I have to do anything else? like disconnect the battery and reconnect. Or use bootmod3 to clear it?

was the code for that exact same location (482941?). before starting the car i did clear the code off the car (with bootmod3). other then that, I haven’t done anything else. no need to disconnect battery or anything.

I've just ordered the two parts the OP mentions above as my intermittent chassis warning fault which tendered to clear now doesn't ( I'm getting 482A22 value spool front left open line and 482A30 value coil front left current controller plausibility error ) - googling these seems to suggest this sensor is the culprit.
Do you have to remove the wheel lining to replace the cable - I'll try and sensor first of all and replace the cable if needs be shiftmr2t

Bah I'm getting the same error codes randomly these days.
The only difference is that I have the bilstein b16 damptronic adaptive suspension instead of the stock EDC. I'm thinking that this error may not be related to the suspension, but some electronic gremlin. Hopefully I can take it to EAS next week to get diagnosed and repaired. It's quite annoying that I have to pull over to restart my car for it to go back to normal. |

I've replaced the acceleration sensor today and cleared the codes but no joy - the cable hasn't arrived yet so I'll replace that as well when it turns up. After that any other thoughts on what this could be?
Also running Bilstein B16 damptronic setup.

Which ones did you check on the shocks themselves? I'm going to look at the cable that sits at the top of the shock (no 1 on diagram).

IF youre looking at top of the engine bay and then at the shock, you will see a wire come out of there. Since you have the B16 just like mine, you will see a black wire (kinda shiny) with a bluish plug. That's the one.
