central locking w163 not working

[bignick]

hi my ml 270 central locking is not working it works when i sync it only once then nothing and sync it again and it open or closes once anybody got any ideas

 

[television]

Is it working from the button inside the car or when the car gets to a certain speed

 

[bignick]

it works from the button iside

 

[television]

OK then do try some new batteries in the key, this is not a normal fault

 

[tony jr]

Do you have problems with both keys?

 

[bignick]

new batterys from MB and re syncd and still the same also front fogs sometimes work and when car heats up wont come on weird

 

[television]

I think then it will have to go on STAR, it must be an EIS fault if it losses sync,,,you could try leaving the key in the ignition for 90 mims

 

[bignick]

now alarm wont stop

 

[television]

The siren could be past its best and maybe causing your problem, you can un plug the siren

 

[WG M-B]

The aam's do cause your problem

Put the key in the ignition and turn it!!!!!!
Does the alarm stop???

 

[bignick]

[WG M-B]

If the alarm is going off while driving then as Malcolm says probably the siren gone nuts!

 

[bignick]

where is it. is it under fuse box?

 

[bignick]

will that mess up my locking problem

 

[television]

It can mess things up, it is possibly under the front wheel arch but I have no means to check right now as no computer

 

[bignick]

Had similar issues. Fixed by replacing the All Activity Module.

Not sure if this is in the right place but I also have a problem with my w163 central locking only operating once after a fob sync. The aam does not show any faults. can anyone throw some light on this for me please?
