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.

i just had my car in to get turbos inspected i also have jb+ talked to the mechanic hes my buddy, and he said unless they can prove that that caused the problem they cant void ur warranty. as for ur other questions idk. GL

The JB+ is nice, but the other tunes, JB4 and Cobb are much better.

I have also heard from this forum that the JB+ isn't the safest way to tune, but I have no evidence.

Failing turbos is a common problem on 335, JB+ would sure void all your warranty since turbos are running at higher boost.

Don't need bypass, do need scan tool just in case. Easy to use too. Buy from Burger or directly from people who make it.
