Master reset Procedure

1- Disconect Battery Cables ( Negative & Positive Cables )you can use any electrical wire as an extension if battery cables don't reach .

2- Hold cables Together for 60 secs ,then let go

3- Wait 15 minutes

4- Make sure all doors are closed

5- Reconnect battery Cables

6- Lock & unlock the vehicles using the key from driver door side (if you have a key fob with no blade key, just lock & unlock using the key fob buttons)

Hi Chad
On the 500SL there are 2 batteries! I assume you talk about the small one in the luggage compartment? Can I connect plus and minus on this battery with the main battery still connected?
I might add that the car is starting and working just fine! No warnings( other than low battery)

Hi Chad - me again
have been through all your steps. Everything seems ok but still the problem with the CD player. This little metall blade is still there. As it looks it must come up from below and blocks any attempt to insert a CD. It looks rather thin , is about 5 mm wide and is just to the right of the left steering pin for the CD,s. The mechanism for both steering pins seems to work. I have also tried to hold the eject bottom down for 5 secs or so- absolutely nothing happens
I get the impression it is some kind of "blocking" of the system? Is there any kind of "unlocking code"
I might add that the display says no CD in place and no CD in the 6- pack magasin behind the drivers seat . If I put a CD in the 6 -pack magasin -I can play it without problems!
Any suggestions?
Kind regards
Jörgen
