SOURCE: 1999 bmw 528i replaced battery and alternator

Replace your battery when its being tested there not testing it under a heavy enough load. A battery could have a dead cell in it and still show good on the charger. I've had that problem a few times.

Alternator not working

What is year--make--model of vehicle? I'd check alternator connections to and from alternator. Check battery and battery connections. Check for charging system trouble codes, see if any?

I had the alternator replaced. Now the AWD disabled light comes on along with the battery light (four dings). Drove it around the block and it cleared. parked it overnight and next am, the same thing

in replacing the alternator most mechanics will disconnect the battery to prevent shorts during the process. This in turn corrupts the CPU program and sometimes it is necessary to reset using a scanner . People use the remove and wait method to reset but it normally doesn't' fix a fault or creates other faults.

My daughters 2000 2.4L Cavalier won't start.

The following are the general instructions on the start of diagnosing any electronically controlled engine or transmission problem.

The engine and the automatic transmission (transmission control is only for automatics, engine is still computer controlled no matter the transmission type) in this vehicle are computer controlled and in most cases when a fault occurs a fault code is stored in the memory of the computer control module. There are exception to this, such as the Mass Airflow Meter and fuel pressure problems. What must be done is to have all the basic testing done such as a scan of the system for fault codes as well as a check with a live data scanner tool for engine functions that are not within range of normal, a trained technician is required to know what is correct and what isn't, then based on careful diagnostics done from a factory repair manual the correct part is replaced or the wiring repaired or the computer replaced (known as the PCM or ECM,ECU), which is very rarely the problem. Other basic checks must be done as well such as mechanical problems with the engine as well as engine state of tune and mileage on the engine. The transmission can have mechanical issues as well such as no gear engagement at all or a failed pump or other pressure related problems. Also engine mechanical problems can and do cause many drive-ability related problem such as rough idle and other symptoms.

Replaced battery and alternator in our 2001 ford windstar, the battery light remains on, took it back to the shop that fixed it and they said everything checked out ok. could the computer need to be

There is no "reset" of the computer that is going to fix a battery light flashing on and off. There is a problem with your charging system that needs to be diagnosed. The computer network should first be scanned for any possible fault codes. If there are no fault codes present, then I would probably replace the alternator again. I get junk remanufactured alternators all the time (it seems there just isn't any quality out there anymore - too much stuff being exported just so greedy businessmen can have children clean them up, stick them in a box and ship them back). There have been some that I have had to replace 3 or 4 times before I finally got a good one.

Computer says 'trans fail safe prog'

Your car is in "LIMP" mode. The computer sensed a fault from transmission and has set it in "LIMP" mode so it's still drivable but it needs to be inspected by BMW. It could be something as simple as a dirty connection or moisture or possible early warning a more serious issues, but have BMW dealer look at it before it gets REALLY costly and leaves you stranded.

My battery light started flickering a couple weeks ago and then my check engine light came on. my car then started freaking out and died. we tested the battery and the alternator, the battery was fine, but...

OK, try to replace the alternator with one that is 'lifetime' warranted rather than one with a '1 year' warranty or less.

Return the bad alternator to the auto parts retailer, and get a higher quality one.

I've had several bad experiences with one year warranteed alternators, some that were bad right out of the box.

I would say that the alternator is, again, at fault, but this time due to cheaper components causing your problem.

Persistent 'Battery / Alternator' Fault

Alternators are expensive parts, especially at dealerships. I'm inclined to agree with you, they should have got it right the first time. No shortage of tools with them, but in fairness to them, intermittent faults are the hardest to detect.
They might come back and say you need a new battery, although it does seem odd that a little testing the first time might have caught that.
Those are the two main items in the start circuit you are having trouble with. Well, the battery, the alternator, the starter and the ignition switch, those four items are the main parts of the start circuit. But with a good battery and an alternator to keep the battery charged up, it will crank over every time. Ideally, that means it will start and run.

Actually a 2008 650i -- battery trouble?

Sounds like an alternator problem. A bad diode can drain the battery(feed back). Replace alternator and if battery is more than 3 years old replace it too. It takes 20 amps just to power the fuel injection. The Bosch alternator should be rated at 100 amps or better. Low output will affect everything you described. Perform an OBDII scan for a look at stored faults. Let the scan be a guide to any other problems that may be present
