CLK 320 (W209)
Help - Dashboard glowing red when locked

Hi all,

I have searched everywhere and cannot find a reason/solution for this. About a minute after locking my CLK 320 the centre circular display on the dash glows a faint red, as if there's a backlight on. I have scanned the OBD for fault codes, but there are none.
Any ideas?
Thanks,
Hesh

I would assume the instrument cluster is glitching. If you can find a temporarily cluster (e.g. from junk yard) to hook up - you can see if the same issue will be replicated on the replacement cluster (I think it will not). If not - replace the cluster and have someone to transfer all the information from the old cluster into the replacement one.

NO LONGER ACTIVE
i'd check the vehicle's battery voltage. Low or erratic voltage can cause weird problems like that..

Your note solved my 08 CLK350 issues. A check engine light turned on but disappeared on restart, Nav claimed turn by turn was not available. Nav and audio prompts in the cluster were missing (---). Radio stayed on when the key was removed. Cranking seemed weak..but always started. My mechanic replaced the battery and it fixed everything...much to the mechanics surprise. Thanks Rodney and MBWorld!
