Hi
I have had my 2003 C-Coupe for about aweek now and find that some of thefunctions keep resetting after I have programd them in.
1. Seat memory function lasts for a few days.
2.Folding rear mirrior in reverse works for a few days and then resets itself, and I have to program it.
3.External lighting needs re-setting after a few days ?
Does anyone have a idea ? , perhaps I am doing somthing wrong ?
thanks for the help

 

if the battery voltage drops below 8 volts during starting, then this problem can happen.

nobody else is using the car?

 

Loose Battery Connections ?

As Sleepwalker states...

"if the battery voltage drops below 8 volts during starting, then this problem can happen"

I would have the battery tested.

If the battery is weak, the voltage can dip down causing that problem.

Does it seem to start pretty strong ? and does it do it consistantly ?

 

At the moment there are 2 of us using the CAR , I have de-actiavated that multi key feature and use the 1,2,3 settings for our individual seating mirror positions.
But maybe I will take the car in and get them to have a look at the battery.
thanks
