The enclosure of the A3 between Aschaffenburg and Hösbach. Friends from Austria call them mockingly avalanche barrier. In fact, it is a local noise protection project that does not just have friends. In the enclosure, it always comes back to fatal accidents and traffic jams. You are happy when you have them behind you. Like on this day.
My 9-3 Aero has almost left the structure behind when all the warning lights come on in the dashboard and the charismatic “ding-dong” sounds. Surprised? I expected that ...
60 kilometers before. Saab Service Frankfurt in Fechenheim. Readers on the blog may still remember the Havarie with my Saab 9-3. A multi-day “business trip” for the blog ended on the wrecker. The Saab team in Frankfurt offered to make me mobile again with a used throttle valve. I refused, preferred to wait for a new part. A few days later the delivery from Sweden arrived, the Saab repaired and I was on the way to Frankfurt.
There are moments when you have a strange feeling. You can't say why and why, it's just there. This was how I felt when I was picked up. New part installed, test drive made, patient healthy - at least in theory. I am leaving Frankfurt, driving south on the A45. The Saab runs well, the queasy feeling remains. I move it carefully, listen to the magical “ding-dong”. I suspect it will come. And so it happens. 60 kilometers later on the A3.
In contrast to the first defect, the car continues to run after the tinkling as if nothing had happened. So he doesn't break down, he doesn't call for a tow truck. But he is sick. After the throttle, the TCS gave up the ghost. A Saab innovation from 1992, first introduced in the 9k. An ingenious predecessor of the ESP that regulates traction in poor road conditions. Starting with powerful front-wheel drive vehicles was a problem until its introduction and required a sensitive foot on the accelerator. 9000 aero riders can tell you a thing or two about it.
The first generation was not switched off, only from 1996 could the traction control in 9000 by pressing a button off. Even in the 9-3 Aero, the TCS already has its authorization with the 205 PS variant. Even more, if, as in my case is a more powerful deer version. The TCS functions were added to the ESP system years later. The engineers from Trollhättan were pioneers in networking the 90ern different controllers and very far ahead.
Today it causes trouble in the 9000, which is why versions with TCS have few friends. And in the 9-3 I, too, the modules die electronic death after 20 years. The good news: it can be fixed. The Saab has to go back to Frankfurt, where the Anna project is already. Now 2 Saab are ready for repair, and a modification of the Jaguar joke is making the rounds among friends.
Why do you need 2 jaguars? Because someone is always in the workshop. And why do you need 3 Saab? Because at least two are always in the workshop. A bad assumption! When two vehicles that are around 20 years old have their illnesses, you have to go through them.
Some time later I pick up the 9000 and put the Aero in the yard. Saab Frankfurt always has a well-stocked selection of overhauled TCS modules in stock, unfortunately none of them fit my 9-3. So I have to wait and it will be a good week before the news arrives and a few more days before I make it to Frankfurt for collection. The queasy feeling doesn't come this time, I'm in the mood for the Aero and it seems to be in good shape. With a new throttle valve and TCS, it runs perfectly, puts you in a good mood, and the Frankfurters have done a good job.
At the end of the article, the question arises as to whether there are leading indicators that indicate a TCS default. I suspect yes, because an unexplained symptom has disappeared after the repair. In reverse, the automatic produced for years a slightly jerky ride. The 9 3 of a friend does the same, in Bamberg it was explained with the age of the Aisin-Borgwarner automatic. For me that sounded very plausible, especially since I was not alone with the symptoms. Well, after the TCS repair, the problem is gone. The Saab now also moves in reverse like any modern car.
What are the experiences of the readers? Has anyone observed a similar behavior? I would be interested!
