Ahhh okay, that clears things up regarding the speaker on the dash.
£160 odd just for the ASC speaker and housing?! Yeah I think I'm with you on that - not worth the time nor money. I'm guessing the repair would involve taking the dash apart which can bring it's own set of problems too. Fake engine noise isn't really my thing - glad they give the option to turn it off.
Thanks for the effort man!
