My DI died last week. I had been following this thread and had made a mental note to pop into a dealer to ask them to check if mine was part of the recall, but of course other things were more important at the time!
I was recovered to my specialist in Tonbridge from Brighton, and made it to them just after they had closed even though they were expecting me - they then did a Formula 1 style DI change and the car was fixed even before the car had been unstrapped from the flatbed! Very impressive, and my thanks heartily go to Motorvation for service above and beyond the call of duty! They were able to check the following day if the DI was subject to the recall, and got a free replacement from Saab.
Moral of the tail - Don't wait for the recall letter, just go to a dealer or an indie and get the serial number checked out. This would have saved me the hassle of breaking down and the missed appointments that ensued.
I will be annoyed if I subsequently receive a letter from Saab - they could have saved me a breakdown.
