Bizarre Wing Mirror Behaviour


Recommended Posts

My memory wing mirrors have started playing up recently and ending up in random places every time I get in the car. This is not good as sometimes its trying to move the mirror beyond its limit. I've also noticed that with the adjuster set to move the right hand mirror, the left hand is moving in unison. With the adjuster set to move the left, only that one changes.

Is this likely just to be the switch playing up and needing to be replaced, or do I have a more serious problem?

Hi -- for mirrors moving in unison check your manual -- it's most likely a setting you need to change. (Attached is from a 2004 Cayenne S owner's manual and covers mirror synch.) And be sure you are using the same key -- unique memory settings can be associated to a specific key.

For the other issues it may be time for a main battery replacement -- strange issues such as memory settings not being stored, etc, often surface when a main battery begins to fail. Not sure what year or model your Cayenne is so I'm not sure how old your battery is and if you've replaced it recently.

Edit: add image.

Ok problem still not fully resolved. Sometimes when unlocking the car its still trying to point the mirrors too the sky, beyond the lock stops. It seems like maybe the system needs centreing and reseting? I'm not sure what the prob is, but it seems to be as if the keys are out of sync with each other and because its moving out of bounds its recording positions for each key that are not possible hence ramming into the lock stop and making a bad noise...

Any ideas how to fix, or am I kidding myself and need a whole new comfort settings control system?
