T6.1 Heated mirror not Timing out !

[mmi]

I thought this could be done via VCDS, but couldn't find any settings.

Could you please share adaptation map of 09-Central Electrics

 

[Extol]

Yes, correct. The time can be adjusted if so desired using the mentioned adaptation channel.

that would be very useful if this can be done via VCDS, I will see if I can find my way to check the timing setting.

Could you please share adaptation map of 09-Central Electrics

I will try that now and update, many thanks for your input.

you are correct 100% it has a 600 second timer. see the screen shot I just took.

I just checked my latest Admap excel file, and it is also shown as 600s on my 2022 T6.1

So 10 minutes seems about right for me.

I just ran it for over 25minutes, but it doesn't time out after 600 seconds. it is continually heating ( even after 25min no signs of cooling down) . can hear the relay switching off when I turn the rotary switch off. so that confirms the BCM is switching the relay correctly.
would some one can check this too, to see if this is something just unique to mine.

If I get a chance I will check mine tomorrow

Hi, please see the attached admap.

I was wondering if it comes on with the timer function only when it is not switched on via the mirror switch but with the heated window switch - Just a thought.

No, it comes ON with the mirror heater switch. In the morning I switch both the windshield heater and the mirror heaters to get both cleared. If I forget to turn the mirror heaters on, they won't come on even if I had the windshield heater On.

We're in summer over here now, but if I remember I will test my mirror heater timing next time I go out.

Tried it today and it doesn’t turn off after 10 minutes. Still on after 25. This is just a gut feeling but the control feels quite basic to me as if it’s just a mechanical switch operating a relay and nothing more. Would be interesting to study a wiring diagram to see exactly what controls it.

I had a brief look, it appears a SMD relay controls both mirrors from within the BCU unit, and that was my first question, if any one got a pin out diagram for the three ports of BCM?. If so it would be an easy fix.

Hi, please see the attached admap.

Thank you very much. It seems that the MY24 BCM is similar as the earlier one (MY20-22) I already got. Although they do have different software
MY24: SW:2Q0-937-090-E HW:2Q0-937-090-C
MY22: SW:2Q0-937-090-C HW:2Q0-937-090-C

Tried it today and it doesn’t turn off after 10 minutes. Still on after 25.

It appears that they stay on as long as the engine is running,

Astounding

I Have the Current Flow Diagram if that helps you? I believe you can identify the Output Pin in the plug.

I tried mine today while out and about. I turned the rotary switch to the heater position, and had no indication that the heaters were even working, and becase it is summer here the mirrors were quite warm anyway. I also turned the rear window heater on (switch on dash) and that had the indicator lamp light up to show it was working, and then turned itself off after around 5 minutes as expected.
Is there a visual indicator to show when the mirror heaters are operating or are mine just not working?

 

[Alster]

There’s no visible indication that the
Mirror heater s are working. I used a clamp meter and checked the current draw.

Can't you see it on the DIS. There is usually a list of stuff switched on eg AC, heated seats mirrors etc.

Checked mine yesterday, 2024 Highline Kombi, definitely don't turn themselves off.

Edit: and yes they appear as a consumer on the display.
