I can see the problem before go to mechanical. It can check BMW and good price.

Great tool for many usages. I bought it to register a new battery on my 2014 X5, and it worked like a charm. Easy to use and without trouble. Great job.

This is an amazing device a must have for a Mini Cooper owner.

Does what is says it does for a good price

The battery in my 2017 Mini Clubman S died. Not only are the batteries more expensive than standard ones (glass mat), you have to disassemble a third of the engine bay to get to it. There are many videos showing you how to do it step-by-step and it’s not difficult but you just take your time to do it. The surprise comes after you put the battery in and find out you have to “register“ tye battery. This tells the car’s computer not to overcharge the battery with the alternator. If you don’t register the battery, you can fry it and possibly damage the electronics in your car. None of the automotive stores in my area had the scanner to register the battery. I did some research and found this one online and bought it for under $100. There are online tutorials on how to do this with the specific scanner and it’s relatively easy. It verified the battery was registered within a minute. This also allows you to see codes and clear many of them.
