How much time?

shendrick · 01-03-2013, 07:06 AM

So my early build 2008 M3 sat for a week indoors over Xmas and now the clock is 7 minutes slow. Naturally this has never happened before so the battery is probably shot. The only question is, for those of you who have experienced this, how much time do I have left? The dealer can't get me in until Monday which is 4-5 days away. Should I just buy a battery now from the dealer, install it myself, and have them code it next week of just roll the dice until then?

you should be fine, I've head of people going a month with hiving to re-set the clock.

I had the same problem. Dealer said everything was okay, charged the battery and sent me on my way. I didn't have a problem until a month later when the clock started losing time and the battery light came on. You should be fine.

I would try getting a charger first if you haven't done so and go from there.

Is there more to these cars than just changing the battery and driving on like any other car?
