alchresearch Posted April 7, 2015 Share Posted April 7, 2015 Have you checked the wiring next? What's a diagnostic showing? Link to comment Share on other sites More sharing options...
elvis1935 Posted April 7, 2015 Author Share Posted April 7, 2015 Had all sensers done had a test keeps saying one on back not working then one on nearside Then I remove all the dash light go for a drive do the test again and it comes up with the other two not work and the speedo keeps dropping out so thinking that it's got to be the abs module Link to comment Share on other sites More sharing options...
geared Posted April 8, 2015 Share Posted April 8, 2015 I had my brothers ABS pump on his Suzuki rebuilt by ECUTesting. They did an excellent job, IIRC it was about £250. We had the codes read at a Suzuki dealership first to confirm it was the pump at fault - they wanted close to a grand to fix it!!!! Link to comment Share on other sites More sharing options...
convert Posted April 8, 2015 Share Posted April 8, 2015 Try here http://www.bimmerforums.com/forum/showthread.php?1395944-HELP!-ASC-ABS-Problem-E39-523i PS I had problems with the ABS on the wife's Audi. Got the lateral acceleration sensor repaired by a chap in Germany (via ebay) for £50 with a 10 year warranty. Link to comment Share on other sites More sharing options...
