Electrical issues ?
Hi
I need some guidance, i keep getting random error messages pop up on the screen, i think they are all related to the fact convenience functions error, they can be anything from a mirror turn signal bulb, a tire pressure sensor, auto light sensor etc they come on and then go off.
I have had both batteries replaced but im thinking it may be the auxiliary battery relay.
When i drive the car the convenience functions error goes away and it says the functions are available again, but if i park, turn it off and turn it on then the error comes back....

If your aux battery is low when you start the car, it will be unhappy... some will reset on their own.
A quick check is to test the battery voltage BEFORE you start the car... then after it is running, check it again... a lot can be told from these 2 values alone.
Been debugging my 2003 SL and had this issue, and a brand new die hard that went bad in a week...
