Hi

Can any one please tell me what are the symptoms of the di cassette failing,
is there an intermittent element to the failure initially?

Not with mine. The car ran great right up to the failure.

I can only tell you what happened in my case. It only happened once; my
93' 9000 CSE LPT 104k miles is on the second DI, so it's not a big deal.
The symptoms went over a period of two weeks or so. The engine would
sometimes refuse to start, but OK after waiting 5 minutes. The engine
finally lost power on a dual carriage way incline, so I couldn't push it
out of the way. It was quite scary. The AA man correctly diagnosed the
dead DI, although I didn't believe him at the time. He demonstrated the
absence of sparks by dismounting the DI & leaning it on the block
while turning the starter.

Mine started missing under heavy acceleration. Never did die, but the
missing just started getting worse. The day I took it to the dealer to get
it fixed I'll bet that I wouldn't have gotten home.

In a former Saab, a 92 9k, I experienced missing, at first under load,
but i am given to understand that it is more frequent to totally fail
without warning.
If anyone has an explanation it would be interesting.

My guess is it has solid state power components, the usual failure mode of a
power transistor is for it to short, which will often cause a catastrophic
failure without warning.

From what I hear, yes. If you're asking this for the obvious reason,
now would be a good time to get one on order, keep it in the trunk with
the tool you need to install it, and wait for the inevitable. Or, replace
it now and keep your suspect one as a "limp-home spare".

David,
With a BT Openworld account I guess you are in the UK.
If so, then you might like to consider these guys.

I guess their prices are better than you will get from a main dealer, though
it's probably best to check first.
