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 mobilize me with a used throttle. I refused, preferring to wait for a new part. A few days later, the delivery from Sweden was there, the Saab repaired and I 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. That's how I felt when I was picked up. New part installed, test drive, 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 this is how it happens. 60 kilometers later on the A3.
Unlike the first defect, the car continues to run after the tinkling, as if nothing had happened. So he does not become lying down, he does not call for a tow truck. But he is sick. After the throttle, the TCS has given up the ghost. A Saab innovation from 1992, first introduced in the 9k. An ingenious predecessor of the ESP, which regulates the traction in bad road conditions. Starting with powerful front-wheel drive was until his introduction a problem and called for a sensitive gas foot. 9000 Aero drivers can sing a song of 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 is causing trouble in the 9000, which is why versions with TCS have little friends. And even in the 9-3 I, the modules die after electronic death after 20 years. The good news: you can fix it. So the Saab has to go back to Frankfurt, where the Anna project is already. Now 2 Saab are ready for the repair, and the circle of friends makes a variation of the Jaguar joke.
Why do you need 2 Jaguars? Because one always stands in the workshop. And why do you need 3 Saab? Because at least two are always in the workshop. A bad assumption! If two vehicles that are around 20 years old have their diseases, 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 remanufactured TCS modules in stock, unfortunately fits None for my 9-3. So I have to wait, and it takes a good week until the news arrives and a few more days before I make it to Frankfurt to pick it up. The queasy feeling does not come this time, I feel like the Aero, and he seems to be in good form. With a new throttle and TCS, it runs perfectly, makes you happy, and the people of Frankfurt did 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!
