#44 of 61 Battery problems by steubenville

Jan 21, 2010 (1:33 pm)

I have a 2001 bmw x5 4.4. I had the battery go dead on me and then I had a jump after that the car started fine, but i still purchased a new battery. a month later the car would not start and they replaced the battery, 3 weeks later it does not start and always after it sits overnight. I had the charging system checked and the starter and all the power system. 3weeks later it would not start for the next two days needing a jump. my license plate bulb also burned out but i replaced the bulb and it still would not work. Do you all think I have short draining the battery overnight, because thats when it happens! I am at wits end on this mystery.

#45 of 61 self level inactive warning by steubenville

I have a BMW X-5 2001 4.4 and The self level inactive warning message came on and it stayed on. I talked with the dealer and hesaid if its level it is probably just a sensor, but he gave me no remedy! Did anyone else have this warning message come on? What did you do?
 
Thanks

Yes! The problem was the regulator in the alternator. The problem was intermittent so when I had the car checked they said the alternator was fine. The problem kept recurring every few weeks. Finally a new mechanic said it had to be the alternator (which I had replaced less than a year before). I had the company that supplied the alternator test it - they had it on the bench running at max output for almost 2 days before the problem showed up. Since it has been replaced about 8 months ago there has been no recurrence. Hope this helps.

#48 of 61 Ultimate piece of S...T! by ih8bmw

60000 dollar garbage! My first ever X5, V8 still has 12000 MLS on it since purchased in 2008. Why? Because it spends more time at BMW service than I can get my hands on it!!!
Do yourself a favor and research before buying it!!!

I had the trans failsafe message appear before. Shutdown and restart cleared it. That was over a year ago. Recently it started doing it more frequently. I read a thread about the alternator/regulator causing a similar problem so I hooked up a scan guage to the OBD port that displays voltage. It read 10.9-11.4 volts while driving. That seemed low. I hooked a regular volt meter to the battery post under hood, it read 13.5 volts with engine running and 12 with engine off. That seemed right. I rechecked the guage connected to the OBD again and it now read 13.4 volts with engine running. That is a definate inconsistency which needs further investigation. Also, I've had an intermittent problem with trans initiating a shift or a disengage then re-engage( can't determine which because it doesn't complete a shift and it happens very quickly, like a hiccup). This happens around 30-40 mph when the automatic trans is in 5th gear. The last time the trans failsafe message appeared, it would not restart. It acted like a dead battery. A few minutes later it started, but the clock lost its program. The service engine light came on, but the car ran great and no more transmission hiccup. I checked code, it was P1890 trans control. I think the symtoms are related. A year ago, dealer had told me the hiccup problem was the trans valve body. They said $5500. I don't believe them. I will post results after looking into regulator and connections.
