Hi Bill, Thank you for your advice. Is the pump not attached to all the brake pipes? There is however, a control unit attached to the front of the pump which has 4 screws and a multi plug, was this part you exchanged? The ECU is located behind the passenger glove box although they are all interconnected due to the complexities of BMWs. I had a diagnostic test done on the car when the ABS light first came on, this showed up as a fault in the front and rear off-side sensors which I replaced. The light still came on and now the speedometer and MPG indicators stop working (but not always). regards, Eric

I have exactly the same problem Bill on my 523i SE AUTO, It is all intermittent though, sometimes the ABS light comes on and the speedo and MPG works and sometimes the other way around and even sometimes the whole lot doesn't work. I changed two sensors (ABS) as the code check said they were not working but the lights still appeared. Do you think it is worth trying a scrap yard for a replacement pump (if that's the Problem) it would certainly be cheaper for an OAP like myself???

Hi All, I am new to this site and live on the Isle of Wight. My main question is "How do you remove oxidization from all the external aluminium trims"? BMW's trims are made of very hard aluminium and the smoky discolouration is very hard to remove. Is there an easy way? or removing them and having them re-anodized a better option. I feel sure buying new could be very expensive. Your thoughts please
