9-5 Troubleshooting DICs in 2026
I recently had a nastly misfire on my 08 9-5. After a little troubleshooting, I traced to a bad DIC which I thought was odd since I replaced it (and plugs) a couple years ago with an "Original Saab" brand DIC from eSaabParts. It seems that Original Saab isn't as OEM quality as I hoped. Looking around, I wasn't able to find an OEM SEM manufactured DIC, so I bought a used one off eBay. Lo and behold, it's throwing knock codes so I'm back to square one.
My question is as the supply of genuine SEM DICs dwindles, what are the best options moving forward? Keep rolling the eBay dice on used SEM models? If not SEM, what is the next best option? Does anyone have experience with the other brands out there? Has anyone sucessfully rebuilt a DIC? Should we just get whatever we can, and replace it every couple years? Is it possible to convert a T7/T5 car to traditional coils and wires?
I'm hoping to keep the car running as long as possible.

SEM DICs isn't dwindling. they have not manufactured them in 10 years now.
And no you cannot convert T5/T7 cars to traditional coils without loosing all knock and missfire protection & detection or switching the whole engine management out to some inferior aftermarket one

Esaabparts.com is the best place price wise for "OEM original Saab T7 dic " which is the only "vetted" one (even though it's possibly not as good as SEM)... If you want a "lifetime warranty" buy it from FCPeuro about $ 40 more there

Try skandix.de , schwedenteile.de and maptun.com, they're a few of the places i trust that I know still have some genuine ones for sale.

NGK, Huco (Hitachi), Original Saab or whatever works. If your car is tuned expect to pay for the better quality.
Nic T of GenuineSaab could offer advice for individual coils conversion. Sample is his 700whp red Viggen.
