I have heard that the saab 9-5 engines tend to have sludge problems?

I have heard this, and also heard that the V6 version tends to have less a problem than the turbos 4's, so i just wanted some clarity and explanation of what the problem is.

Hi. When I considered my second Saab vehicle (new), I was told by the service tech the opposite, the V-6 tend to have more issues.
