To Gary,
I have the exact same problem you have; loss of central locking (intermittent) and temperature display shows random dots. It's a 2002 Espace, 2.2GTD. I bought it second hand and the previous owner has had the same problem; he opted to replace the dashboard alltogether. I'd rather not do that. Did you have any luck at fixing it?
Thx
Mike, June 2009
