Hi there,
I have a 2005 SL500 which has a BATTERY warning light and visit workshop message on the dash. The battery has been meter read as has the alternator and both read healthy. Any ideas?
thanks in advance.

There are 2 batteries, have you checked both?

I have. Both starter and auxiliary are testing good!

First, try clearing the code and see if it comes back. The red battery message is a common appearance and doesn't definitively indicate trouble. You need a scan tool, such as the Foxwell or Autel, or someone who has one.

Thanks Tom,
I will have a crack at that. Thanks for the insight.

Try checking your charging volts, should sit about 14.1 V
I used my iCarsoft and it cleared the red battery warning.
