FRM module error/ not communicating

[Julius02]

I'm seeing FRM errors in ISTA D and they appear sporadic. Sometimes the unit responds and other times it doesn't.
What things would I be noticing if this unit is failing?

I do find the auto wipers and lights are slow to respond at times and the lights can stay on in daylight.
Additionally sometimes one of the electric mirrors doesn't fold out.
When trying to initialise the rain sensor in ISTA-D i've also had a communication problem with the RLS...

Any help would be great, thanks.

Windows might not work as well.

There's an extended warranty for it (at least in the US). https://www.1addicts.com/forums/show....php?t=1550971

I think there are other threads discussing it too.

sounds like it's fried, no reset will fix it
needs a new one, also needs to be coded to your vin

you could try pulling it and reseating it, in case of any contact issues,
I did see a youtube video, were a guy pulled one apart and there was a fuse blown in his one
