MISS BM 712 Report post Posted September 21, 2013 For E38, 728i 96Randomly last night, my Speedo stopped working periodically and my ABS and Traction Control light are now permanently on. Have tried turning car off and on etc. I think it may be the vibrations as I got my exhaust modified... I am assuming it is the sensor, but can someone give more advice, and possibly a DIY on how to test and fix? Should be similar to an E39.. Quote Share this post Link to post Share on other sites

MISS BM 712 Report post Posted September 24, 2013 Seems to only being doing it when it is wet - fine in dry weather.. typical right when it might ever be required! Another thing has started coming through - petrol gauge, and range gauge are going a bit funny on me... Light goes on, goes off, beeps at the 50k mark, did this the whole way home... Only when the ABS/Traction Control, and speedo stopped working. Quote Share this post Link to post Share on other sites
Ahmedsinc 414 Report post Posted September 24, 2013 Possibly a knock-on effect from jump starting the car? I know nothing of E38s other than the electronic wizardry starting getting fairly complex from then on. Perhaps Hotwire would have a theory? Quote Share this post Link to post Share on other sites
