Goonrider 0 Report post Posted March 30, 2011 I have a 2001 X5 4.4 V8. Battery ran low the other day. After getting it started again the car seems to feel like its missing or the transmission faulty. Read on another website when the battery runs flats it sends all the modules and stuff haywire. Can anyone confirm a fix for this. Also an alarm sounds keeps going and doesnt stop and the radio does not work? Quote Share this post Link to post Share on other sites
elmarco 56 Report post Posted March 31, 2011 Get it checked by an expert. A dead battery can take an alternator with it and cause all sorts of havoc with the electronics. And an audible alarm is normally a sign that something is wrong.... Quote Share this post Link to post Share on other sites

So if your altenator is on the blink or not charging the battery, this could be the case. After you get your battery / charging circuit checked .. have it scanned and a reset of the fault codes.. Drive it for a little bit then get a rescan. Quote Share this post Link to post Share on other sites
