yeah, i was told as it would not affect performance of the car and hence they would not fix it. which is a load of bollocks as i had just got them to fix a dash rattle under warranty. I have a feeling they knew there was a chance they might have to replace the whole seat and obviously they didnt want to fork out. Mine was audible whenever your back was propped up against the chair, i.e. pressing clutch all the way in, brakes all the way in, or just pushing back against the footrest

I've just put a bit of lumbar support, which seems to kill the squeak.
The back panel is a bitch to get off and unless it gets worse I won't be trying that.
