Help! I 4B5: DSC Steering column am hoping this community can shed light on this mystery
2006 325i BMW with ~24,000 mi
taken care of - babied - serviced regularly and garaged up until a year and a half ago
2/17 Brake specialist - BRAKE FLUID FLUSHED AND BRAKES INSPECTED, used something DOT 4 fluid and reported no issues, brake pads good
2/17 later the same day - oil change at Jiffy Lube - technician checked brake fluid in the brake fluid reservoir using an electric moisture content sensor and visually and said was okay
Not sure if it matters for this story, but the battery died and was replaced a couple of months ago
FLASH FORWARD ONE WEEK…
2/25 Raining, I rushed to get into the car parked on the curb in front of my house. I start the car and drive two house lengths to the end of the street, apply the brakes, pedal drops and brakes fail. I roll through the stop sign 3/4 way into the four way intersection before I was able to stop the car
Took car back to brake specialist around the corner after I determined I could press really hard on the brakes to get them to stop.
Brake specialist inspected the car, called me and told me they see that the car has damage on the drivers door that they didn’t see the week before
They keep the car overnight and call me to tell me that they have found a problem with the STEERING ANGLE SENSOR
When they reset the steering angle sensor and drove the car, the brake light and traction control light would come one and the brake pedal would go soft
They were able to reproduce this multiple times.
They were unable to fully diagnose what the issue was
They advised having the car looked at by a BMW specialist to determine what was happening with the brakes.
I picked up the car and saw the damage to the door. The brake specialist believed the issues were related to the damaged based on the position of the damage
The BMW specialist advised to contact insurance first.
Insurance contacted and a claim started. Car flatbedded to an authorized repair facility.
Authorized repair facility has car a little over a week and replaces the drivers door, but couldn’t diagnose the safety issues and told me they would send it to the dealer, but that in their opinion they do not believe that the safety issues are related to the car being hit.
Dealer gets car after body work completed at the authorized repair facility and does an initial inspection.
They inspected brake fluid reservoir and found BRAKE FLUID LEVEL WAS FULL but BRAKE FLUID CONDITION POOR AND RED IN COLOR. They found that the brakes had excessive play and were spongy and no leaks were found
The dealer performed a vehicle test and found fault codes 0094B6, 0094B5: DSC steering column switch center internal fault.
Code 005E43 DSC steering angle sensor adjustment
Dealer performed test plan “DSC STEERING ANGLE SENSOR” and determined the steering angle sensor internal fault stored 13 times
Dealer recommends replacement of the STEERING COLUMN SWITCH CLUSTER and reprogramming
Insurance company says I have to prove the safety issues are related to the accident and are not willing to pay for the repairs
BMW NA will not assist until liability is determined and say even if the determination is the car has an inherent safety issue, they will not guarantee assistance
Okay, so I asked a separate BMW specialist if the accident could have caused any of these issues. This is what he told me:
The BMW expert cited three links:1) the impact to a stationary car could cause jarring that could damage the sensor, 2) the wheels may have been turned out when it was hit and shifted abruptly affecting alignment and steering, and 3) when the car was hit it may have been dragged and rocked hard against the curb, further affecting alignment and steering.
The insurance company says I could have gotten this information from anywhere and are still claiming it is not related.
SO THE MYSTERY>>>
Is this all a bermuda triangle type coincidence/twilight zone freakishness?
How can a does brake fluid go bad in one week - if indeed it was bad when the brakes failed? Or in two weeks when the dealer inspected it? How does a car in perfect operating condition coincidentally have steering and brake issues after being hit - related to car being hit or inherent BMW fault with the vehicle?
Do you think that the steering and brake issues are not related to the car being hit? Why?
Do you think that the steering and brake issues can be related to the car being hit? Why?
