If so, I might have solved my constant “ABS and ESP Currently Unavailable see manual” Msg.
Having cleaned both front sensors and reluctor rings ( not very gunky) with no joy. Purely to rule out the sensors (as MBII said visually inspect all 4.)
Note my guess is its all really an undervoltage thing.
I drove to clear the msg. By driving and steering left and right . Parked the car msg. Free and then
I cleaned the back left sensor and reluctor ring.. lots of grey brake paste/ brake dust on the reluctor ring.
Started the car ... up came msg.
Restarted x5 no msg.
Having all the kit out, I thought lets clean the right back sensor and reluctor ring
That too was quite dirty.
Restarted the car. Dam msg. Came back
Somewhat dissapointed as the shutdown voltage was at 12.7V so pretty high for her. And upsetting my undervoltage cause theory :-/
Drove the car 15ft clearing the message ... and parked her.
Went to neighbours BBQ ... sod the car.
This morning opened door. Voltage at 12.2V ... more like it.
Let her shutdown, and it climbed to 12.5V not great, but as normal.
Started the car
WTF ... I was defo expecting due to low voltage the Dreaded Message. But hey No msg.
Restarted the car .... thinking no chance ... NO Message
Restarted the car again No Message
Restarted it 5 more times ... no message .
I don't feel lucky enough to believe it but hell....
Far too early to celebrate after all we are talking about a “high end mistress ... “ and all highly strung thoroughbred fillies arent easy to live with ...
I then thought, what if the act of unplugging the sensor, automatically triggers a requirement to reset the steering angle. ( like disconnecting a battery does ) Then maybe I solved it on completion of the left back sensor , then by undoing the back right sensor it triggered the reset requirement and then now it is cured?
Too optimistic I know
Note for the wheels to spin ( to clean reluctors) , the key has to be left in the car, albeit in the off position .. so not absolutely turned off?
Course I still have to sort my 2nd dodgy Mb battery, but thats easy; either they replace it or I just buy a new one.
