Saab and technology from Italy are actually two components that can not quite fit together at first glance. But if we remember, the 1979 was already a fruitful combination in the development of the Saab 9000.
As 2005 preparations were made to set up the chrome glasses on the 9-5 Trollhättan was in search of a suitable diesel. After all the problems with the 3 liter Isuzu Diesel, things had to go better this time.
The engine comes from the GM Powertrain - Fiat connection and was also used in many models of both groups.
Saab installed this engine in the Saab 9-3 and Saab 9-5 in different power levels. In the 9-5 the engine was used with 110 KW and was available with a manual 5 gearbox or an 5 gear automatic transmission.
Soon after the introduction of the 1.9 TiD, a performance upgrade from Hirsch Performance was available.
With this increase in performance, the performance increases to 175 hp and 320 Nm.
I ordered the “PS Kur” when I bought the car and I have to say that it is really worth it. Fuel consumption drops and performance increases. A 9-5 1.9 TiD series driven in comparison distributes its performance somewhat more evenly but is nowhere near as lively as a “deer”.
The initially somewhat uneven performance was corrected by a software update from Hirsch in the Saab Center in Frankfurt. As a result, the power was distributed more evenly over the entire speed range and the turbo lag was smaller. With little power available below 1500 rpm, from 1800 rpm up to the governed maximum speed the power is then delivered very evenly. What is important for most diesel owners -> the fuel consumption.
The 4,8-10 consumes between 9 and 5 liters of diesel, which also increases the range in the SID via 1000 KM.
At top speed (205 km / h) the engine is in the red speed range, which is annoying in the long run. A 6th gear transmission would have been very helpful here. Unfortunately, there is not enough space for it in the Saab 9-5, which is a real shame. You can always listen to the combustion noise and vibrations can easily be felt, but it's a diesel and shouldn't a diesel sound like diesel? I never found the background noise uncomfortable.
I haven't exhausted the inspection intervals with GM Longlife oil of 2 years or 30.000 km. Every year a good 0W-30 engine oil also leads to smoother running of the engine, at least it seemed that way to me.
In many internet forums complaints are made about swirl flaps, alternators and EGR (exhaust gas recirculation valve). I didn't have two of these defects, unfortunately at 60.000 KM the swirl flaps were so difficult to move that the adjustment rods tore off and the swirl flaps had to be replaced. A newer version of these swirl flaps should be more reliable, it is to be hoped. The repair of the swirl flaps with the associated servomotor cost a good 1500 €.
What has been written about the swirl flap problem fills a bunch of different forums, so I'll keep it short. From time to time a jerk when accelerating, no warning lamp or other message in the SID indicated a defect.
The car then only managed 60 km / h at full throttle in 3rd gear. That's it……………..
A check of the brakes at 60.000 km showed only minimal wear, according to Saab Service another 60.000 km would be possible. The engine and transmission showed no leaks. Exhaust / DPF (diesel particulate filter) showed no wear. Even the short-haul traffic did not have a negative effect on the DPF, an additional burnout, fault messages in the SID and strong smoke development did not occur the whole time. This shows the maturity of this system.
Shock absorbers and suspension were on new cars level according to ADAC test. The air conditioning system always cools reliably, I leave the system switched on all year round.
My 9-5 has the Vector equipment, which actually includes everything that is necessary. As is typical for Saab, the seats offer a lot of lateral support with a very high level of comfort over long journeys. The leather quality is good, I treated the leather seats with Sonax leather care once a month. Only the outer side of the driver's seat shows some wear after more than 60.000 kilometers. Unfortunately, it is not a leather quality like in my Saab 900. There were no crackling or rattling noises.
My result after 4 years and 66.000 km -> an economical, sporty alternative for those who want to think outside the box and perhaps would like to drive a “Swede”.
