Heater mirror and static errors
Hi everyone, my heated mirrors are not working. I’m getting the following codes,B11F814 , mirror left and right side
U140600 , a static too high error
B14E115, heated back rest front left for some reason? (Heated seat works though..)
I took both mirrors out and measured the ohm, left mirror gives about 5.5 but the right mirror is a solid 0.
left mirror connectors give about 5/6volts, right mirror connectors 0 volts.
The right heating element is dead, I’ll have to order a new one but the connectors are also 0 volts, any idea on a fix?
Or is ecu cutting power there because of the stored error?
Regarding the static too high, could it be my wired dashcam? This is fused and grounded though.
the heated seat error might be caused by a sensor? Not too sure where this would be located. Not keen on tearing open the seats, as long as it works I’ll leave it be.
All help appreciated

Most likely the control module is not even attempting to send out voltage due to the code, Throwing out codes and not clarifying what control module the codes are from is never helpful.
The correct text for the U code is probably quiescent current too high (current flow out of the battery when the car should be sleeping); yes, probably your non-factory device.
The B9 runs the seat bottom and the seat back heating separately. The seat bottom heats, but does the seat back? You'd have to provide a better DTC text to explain the actual error. For example, something like
Heated Seat Backrest; Front Left
B14E1 15 [009] - Open or Short to Plus
actually gives a what component and "what's the issue".

Mirrors:
fault B11F814
status, static
Heated outside rear-view mirror ’open circuit/short circuit to ground’
priority 5
malfunction frequency counter 1
unlearning counter 123
Gateway:
fault U140600
status, static
static current ’too high’
priority 6
malfunction frequency counter 1
unlearning counter 123
Central Electrics:
fault B14e115
status, static
Heated backrest front left ‘Open circuit/short circuit to B+’
priority 5
malfunction frequency counter 1
unlearning counter 123
Im using OBDEleven for this. Seems like the bottom seat is heating but the backrest is not.

There's a connector station on the floor under the seat. The heating goes through the green one. Pin 3 is the ground. Pin 5 is the seat bottom. Pin 6 is the seat back. If you unplug it, you should be able to make a resistance measurement on the seat side connector from 5 to 3 for the seat bottom and 6 to 3 for the seat back. You'll probably get an open circuit for 6 to 3. If you get a value, it's going to be something with the wire from the J519 to the connector station. If you get an open reading, there is a 2-pin further in the seat you'd measure at. But most likely it's the grid for the seat back is broken.
