Battery charger for reflash

[Lambobimmer]

Is anyone using a battery when they reflash using their AccessPORT? I have not, but I am concerned about the battery dying during the process. If so, what brand/type are you using?

Also, is there a way to turn off the angel eyes. When you power cycle the car my angel eyes come on and they will not turn off with the switch.

I didnt purchase the AP for my 1 yet, but I had it on my EvoX and I was having problems with the maps and had to contact cobb to fix the problem and during all of that time my battery didnt die. they tell u to be cautious, but you should be fine imo

It won't die

had mine in and out. our cars are new enough that the batteries should be solid enough. Now say in a few years as the battery is getting to the end of it's life it's probably worth it. I did have the problem in the past with a shark injector where it wouldn't update my 6 year old car on it's original battery, put charger on and no problems.

No charger used here, turn off all accesorries, including running lights (Those are controlled via the stalk settings) and you'll be fine, the whole install only takes about 15 minutes.

So how do you turn off the running lights? I have yet to figure it out.

with the engine running, use the rocker switch on the left stalk that controls the dash read out. If you push that rocker switch up or down it will take you in the the Settings menu on the dash...look for the picture of a key with a check on it...use the button on the end of the stalk to select.

use the rocker again to scroll through the different things you can set, until you come to the option that has an icon that looks like a sun...end button to select it, scroll down to off, select again...done and done

its all in the manual, page 75 i think...I just had to reset everything after the hpfp reflash.

An inexpensive battery charger will give you an added layer of protection and a whole lot of comfort. They are under $50 at your local autoparts store.

With the gigantic 50lb BMW battery you should be okay but I would use a charger anyhow.
