After two trips to my BMW dealer, the recommended solution was to replace the other 3 wheel sensors and the control module. This is only $1400 dollar on top of the $600 I just spent on the 90K mile service.
The problem started with the ABS/ASC lights coming on intermitantly -usually in wet weather. This also, occasionally, prevents use of the cruise control.
The diagnosis is cracked wheel sensors. The extended warrenty covered the first one replaced two months ago. But as they have now been informed of that other three are cracked they won't cover them because this is not a "Safety" issue and has been determined to be a design flaw on models manufactured in Canada during the 1999 model year.
Is there an alternative fix or temporary repair? It's not that I'm being cheap. I am putting $600 of new tires on it next week before the weather turn foul and would like to delay this expensive repair.
Also is this a repair I can take care of? I cannot find a repair manual for my 1999 5 series. I have moderate mechanical skills, mostly timing belts, tune-ups, exhaust , and suspension experience.
