Hello, since I can’t get into the Saab forum for unclear reasons, I’ll try it here. I’d like to buy a 9-5 combination from EZ 03 to approx. 80 Tkm soon. Motorization 2.2 TID, 2.0t or 2.3t 185 hp each hand switch (the large diesel is eliminated from the known cause). Now to my questions: 1. Do the above engines have control chain or ZR? When ZR, when must be changed? 2. The diesel should be quite unproblematic, what awaits me with the two turbo ottos? Special Mack 3,0 TD? 3. What about your experience with the above-mentioned petrol engines with the consumption (please don’t use BC!) 4. I read that some gasoline engines tend to form black sludge with the result of accumulated engine damage and Saab should therefore allegedly grant 8 years warranty on the engines? What about it? 5. Am also interested in tips on these types! Thank you for your advice!
