Do you have to reset computer after installing a battery
We found at odd times the alternator shuts off leaving only the battery to drive the engine which soon shows
warning lights and then a total shut down and a dead engine, yet the Ign warning light never gave advance warning.
After say half an hour you could jump start the engine after which every thing is in order and the alternator charging
up the battery
Undo your negative battery terminal and turn on ignition key leave on for a couple of minutes, turn off key and install negative terminal. It sounds to me that your altenator needs to be replaced, it is working until it gets hot, the altenator is faulty, would not have anything to do with computer, however if u are going to chang it yourself make sure u disconnect negative terminal from battery to prevent shorting the altenator wires against something that would be grounded.
Hi there Jwhalen, a nice tip about the ignition key, It's when a problem comes along there are so many interesting things that pop up Probably the best way to learn just how things tick Yes I'm thinking it's the alternator and happy to hear about the computer side of it, hopefully I will get my hands on the X machine next week and have some fun. O' yes I sure will disconnect the battery before work. Many thanks
Hi guys, I ran to flat battery and RACV guy who came to fix it disconnected the + terminal and reconnected it. now computer is asking for a code before it starts, I have no idea what is the code. does anybody knows how to reset this code please? Is it OK to charge the battery with external Charger through the jumper points while the battery is fixed in the car?
I don't know anything about the code. You can charge the battery in the car. Start a new thread so people can respond. The thread you are on is four months old.

I have a 2005 x3. Replaced the starter a month ago, the alternator 2 weeks ago, 3 days later alternator is fried again. replaced alternator Now my car will not stay charged still. Both battery and alternator our testing good. Will the battery reset resolve this issue?? I also read the IVM module may need to be replaced. Need help, the mechanic I took it to said he couldn't figure it out.
There is no need to disconnect the negative as stated above. Reprograming a key after a battery change, which I have done, is a very simple procedure. Check YouTube for easy 30 second procedure.
