Does anyone know the difference between these codes?
I found something online to check codes but I'm not sure it's right. My codes from my S8 on the left vs another one I looked at a while back. Something about glass I think
Current S8 first followed by previous S8:
3L4 vs 3PN
4KP vs 4KV
4GP vs 4GM
Also what is 1N3? something about variable speed??? Mine has this but I'm not aware of the function
Thanks
Rich
