Hi, I'm new to the BMW tuning world and this forum but I was wondering if anyone knew if I had a warranty issue during my extended warranty period...do I need to have a CAN tool or BT tool to clear tuning codes or something?

I've been reading on the burger tuning website that the CAN tool is only avail for 2008+ ...does this mean I don't need to clear codes?

If I have to get a BT tool where and how much is it and is it easy to use to just clear codes before I take it in for warranty work

...also I have it set at 75% ...should I or do I have to do the by pass thing?

Sorry for being such a newbie

Thanks in advance.
