CTEK is what BMW uses. Reason CTEK gets warm is it charges differently than the Noco.

A good couple of years down the line, and just wanted to thank you for this. I’ve just installed mine panel in my g31 and it’s working a treat.

I hope you're using the under-hood (bonnet?) battery posts for charging.

Hmm...I wonder if Mc535d saw this info in post #3?

Take note of the yellow & green highlighted text...if you do get check control warnings after trickle charging the battery...it may be due to bypassing the IBS (intelligent battery sensor):

Good point - But I have bypassed the IBS by not charging at the negative terminal. The positive, yes, but not the negative. That’s at the chassis grounding strap. This is as per the BMW instructions on trickle charging in their video https://youtu.be/bIqDU9sQwT8 (listen to the narrative that accompanies the video)

It’s reading across the terminals fine, but will be cautious and double check with BMW on their instructions), before I plug it in for a proper trickle charge
