Hi there, I have a 2002 Saab 9-3 SE. I live in Ontario Canada. My cassette recently failed on me and I had trouble finding not one original Saab cassette for sale available to ship to Canada. So I purchased an aftermarket Standard Motor Products UF577 one off of rockauto.com
After driving for one day my engine light flashes like crazy when i'm really on the gas. I guess it is a bad quality cassette. Does anyone know where I can get a genuine Saab cassette for my T7 car? Or should I trust a used one off Ebay?

A used (Ebay) one is a crapshoot as it were. Might be OK, might not. They are usually good for 70K miles. If you figure 15K/year typical, that would be 5 years old max. If you look at a SEM, there's a label with YYWW (Year / Week) of manufacture. Many of the sellers out there are junkyards who have no idea if it's actually good and doesn't throw codes under load. Best bet would be buying one from another Saaber in CA who will tell you if it ran without any codes.

Or, as Jvan suggested, Rock Auto, new, NGK, done.

The NGK that RockAuto sells is almost certainly a SEM. You can do a search, it's come up lots in the 9-5 forums. I don't know what the absolutely latest info is.

You can get an Orio (marked up) T7 cassette from this Canadian shop:

Budd's in Oakville will do the same, I don't know their price.

If you are somewhere vaguely close to Toronto, Beacon or Zoom may have a good used cassette.

I can verify that Mike's and Cookstown don't have any DI cassettes in their you-pull yards. You may have luck with some other yards. Make sure it's a genuine SEM and look for a date code that's hopefully past 2010, although 2005+ is not too bad.

Rock auto NGK Red Cassette (received mine monday and fitted it yesterday)
It's working 'Fine'... so far.
Does come in an NGK box which has a 'made in sweden' parts identity sticker .
Also does Not have the SEM date code stickers on the Ali casting. Glue residues visible where it was removed tho..
Casting date grids look to have been dremeled off, albeit before painting
Also the detail finish of the Black plastic towers part is a little bit lesser casting quality than the SEM ones I'm comparing against.
Hopefully insignificant artifacts from aging molds..
Does come with Dielectric grease in the spark plug holes
Few other choices though.. besides possibly hoarded 'old stock'.
Don't believe Gustav's (nordic) are Genuine, albeit only based on casual observation of the actual items.

Easy telltale for a failing DI ...in stages.. are:
1) cracks on the Base of the black plastic piece
2) Leaks of green oil on the white Coils (remove the black plastic to see)
Although when a well advanced failure ..Green oil is visible on the spark plug top(s)
3) Cracking of the Blue relay case
4) pinholes where the Transformer arcs against the ali casting (tiny /hard to see.)

By the time one spots green oil leakage, the DI is well and truly on it's way to the trashbin.
Rest of the visible damages only confirm it's moribund condition.

That's curious about the sticker being removed... although I am not familiar with the red DIC's as much as the black. Last I heard, NGK was shipping with SEM labels intact.

I wonder if this relates to my other post about ORIO now selling a different cassette. Perhaps there are now licensing issues with the SEM name, etc?
