Thanks guys... This morning send the car to Autobavaria to diagnose. Hopefully it just the sensor. They did mention there was before the problem from the brake controller..Sure or not this guys..!!
Attach the photo of it. When this happen my Speedometer not functioning and my brake was cut off with no ABS and just operate as normal brake.
Thanks Again.. OK, some update on the ASC/ABS light “on” and when it “on” my speedometer will not function. The light on/off intermittent. Checked other forums and it happen to afew Bimmer before. From the feedback some said base on their experience are faulty sensors ( pulse wheel speed sensor, ABS sensors), some said ASC/ABS relay faulty ( I'm not sure where this thing located), the worst part is ECU.
In my case, there was abit long story regarding this.
Saturday send the car at 10 am to Autobavaria Ipoh and it ready 4:30pm. They said there was a faulty signal from rear left wheel sensor. They found out the a socket is loose and no good connecting. They cleaned it up and connect it back. Diagnose again and reset. - RM192
I took the car and the light was off, drive it home. But just about to reverse to garage the light "on" back again. How frusteted !! Arrggh! Drove it back to AutoBavaria and show it to them but because of they off at 5:00pm i make another schedule on next Saturday.
Call up
Shu/328 Banana Split and got to know Taiping Workshop can check for me. Drove 10pm night to the workshop knock! Knock! the workshop. He check and same thing the rear wheel sensor faulty. Checked again found out the sensor was not tighted by AutoBavaria ( Or may be the screw loosen) OK this time i change the whole sensor to new one!. Tested ok. Pay RM500.
The light goes off. Drove back to Ipoh ..Damn!! just about to reach Changkat Jering Tol the light when “on” back again!! Ahgghh!! Feel bad, drove back to Ipoh and reach home at 2:00 am in the morning with unsolved problem. OK get ready to the worst – suspected the control unit faulty.
Next morning Sunday. When to Taiping workshop again with shu and another rc friend the pomen told me he got second hand unit ECU. OK change it ! Cost me 1K. And I change back the new sensor that I changed that night back to my old sensor. The problem solved till now!!
So the cause my problem is the worst one - ECU faulty!!.
