Mirror adjusting fault Octavia MK1

[Madsen7711]

Hi

 

My mirror adjustment doesn´t work. When I select the rigth mirror on the knob and adjust, the rigth mirror moves. When I Select the left mirror, the rigth mirror moves. The left mirror motors works when I supply them with 12 V directly. Also the left door won´t lock/unlock with the central locking. I have changed door lock actuator, and it didn´t solve the problem. 

 

Anyone who knows what´s wrong?

I don't know what's wrong (with the car), but strongly suspect broken wires in the driver's door bellows.

As above check the wiring in the bellows but also the connivence system does have some basic diagnostic help and some measuring block data which can help.

I have inspected the wires, and found no obviously fault. Also tried wiegling the wires, while engaging the central lock, with no result. I suspect the central lock module perhaps?

Broken wire in door loom, or most probably the electric window motor in the door, fills with water and corrodes the pins in the connector block, loads of threads on here to show you how to replace or repair.

Thanks everybody. I will start checking the wires and connectors, when I get back from holliday.

Hi everyone I have the same fault, any progress yet? 🤔🤪

[Madsen7711]

HI

Yes. 

 

The wiring in the door loom had seen better days. Soldered new wires true the loom without result.

I suspect the window motor. It was full off water and the connectors corroded and one broken. A new window motor cost 5500 danish crowns, the same as 630 £, so I´m looking for a used.

If you mean that when you adjust the left mirror the right one moves as well (or it may be the other way round) then it is normal behaviour programmed that way from the factory but can be disabled/enabled using VCDS, it took me several years to work out what was going on, why I was always having to reset a mirror that I had only just set, when adjusting a mirror I am looking at it and cannot see the other one moving nor would never have expected it to.

 

I am blind in one eye so others may see the unwanted movement of the other mirror.

 

I cant see any reason for the function other than if a PORG drives the car they would move the seat forwards and adjust the mirrors down and this way they only need adjust one, problem is it does the same for the side to side movement.

 

I do hope you havn't spent hours searching for a fault that is a "feature".

[MiloFrance]

Interesting. I'll go and look again, but the left (drivers side) doesn't move at all...

[J.R.]

Yes, having reread your posting I understand that now but it does explain why the other side moves so one less thing to consider.

 

Others have already advised re the door loop cable breakage and corroded connections.

 

I scrapped my MK1 when I could not open passenger doors and fuel flap, had I known about VCDS or the common door loop fault I would not have needed to, it was so reliable I became totally out of touch.
