Passenger mirror tilt on reverse
 

When reverse gear is engaged the passenger mirror tilts to ease looking at curb. This is absolutely cool, but when I start driving forward the mirror doesn't return back to it's original position at all. Did anyone experience this?

Is it a software bug in mirror control unit?

Any ideas how to approach fixing this?

1 out of every 7th time my S8 also does this! (Not very helpful, sorry)

Singh, it maybe not just a software in mirror control unit...

I think the problem can also be connected with memory seats function, i.e. it seems car doesn't memorize original position of the mirror when we press "memory+1" buttons. When it comes to restoring the position during driving it just doesn't know the original position or thinks that current tilted position is already the right one...

To test that theory just put the mirror fold swich to the center position. If the mirror comes up then there may well be an issue with the memory function.

Conan, as far as I remember the mirror is designed to tilt only when switch is in passenger position.

When the switch is in center position the mirror won't even come down.

That's my point. If it comes back up when you switch from the passenger positin to the center position then thgere is no fault with the motors etc, just a logic fault.

Checked today. Mirror doesn't come back when switch is returned to center position.

Another thing I noticed: when reverse is engaged the mirror inclinates, but doesn't return. When I engage reverse again the mirror inclinates even further as if the system completely forgot the mirror had been inclinated already. The third time I engage reverse the mirror inclinates even more and just stops at that position as there is no more technical possibility to inclinate...

There are a couple of motors in the mirror housing that adjust the mirror. Can you adjust the mirror using the up/down/left/right buttons?

If not I suspect that either a wire is loose or a motor gearbox is US in one direction.

Yes I can adjust mirror position with arrow buttons without any problem.

Mystery :-)

Weird! Must be a memory chip issue. Ian's the man for this sort of thing. He'll be along in Due course.
