I think the problem is that if you encapsulate 4 ignition coils and their drive circuit, and strap them on top of a hot vibrating engine, they fail! There's a very good reason the coil on a C900 is mounted right behind where the bonnet meets the grille - airflow. Coils get hot, as do ignition amplifiers. Locating them immediately on top of an engine is not a good way to cool them. > Is DI failure regarded by Saab as a warranty item, BTW? In the UK it is. -- Grunff
