After 50 KM I drove my M3, the screen showed "Dynamic Damping Control
Failure". Next day, the screen further showed another two signals: first, EDC
Mulfunctioned; second, DSC Mulfunctioned, on the way to the service dept.
I can understand why the signal of EDC mulfunction showing up since the
signal of "Dynamic Damping Control Failure" showed first. But I wonder if
there is any relation between Damping system and DSC. If the mulfunction
of DSC is related to EDC due to the complicated computer sytem, then I
suspect any minor issue will cause serious safety issue, right?
Last saturday Dynamic Damping Control Failure happened again, but this time
I asked the local service Dept. of BMW to send a technician today to drive
my car back to the service dept. for repair. Therefore, I have no chance to
check whether EDC and DSC still function or not on the way to the repair
factory.
This afternoon, the manager of service dept. told me thru telephone that
after computer diagnosis, they found there is a wire not well connecting to
the sensors and therefore it resulted in the failure of Damping control system
again. For conservatism, they will check and test my car tomorrow morning.
But I doubt what he said because I think when the issue happened first time,
service dept. should carefully check the whole related hardware system
including sensors and wires. I will ask the service department give me the
these two repair records. I am afraid that there are seriour flaws in the
damping control system. Just my guess. Will keep you posted if there is any
progress. Thanks.
