Hey FIS-X,
I don't know how much you know about our "TÃœV" or better the "HU" (Hauptuntersuchung, it means the inspection you have to pass every two years).
My brakes didn't fit the minimal deceleration of the complete vehicle. I guess it was the inspector, that was not so happy with my car.
I had to replace the braking caliper, cause the one on the left side didn't move on the pivot and was braking only on the inside of the disc. Ironically my brakeforce doesn't get better, but I passed the test cause the front brakes was getting better in a big way. Don't know why... I guess the inspector didn't push the brake really hard. And the other inspector said that the brakeforce on the rear axle was high enough.
The second problem was the AU, the emission-test. The catalytic converter and the lambda probes had no function, I had to replace them too.
I replaced the lambda probes with new ones and the catalytic converter with an old one. And I failed the test again. But the emission values get a bit better.
I'm very sure it was the inspector, cause he didn't heat the engine right and the catalytic converter was cold, so the emission values was terrible... I replaced the catalytic converter with a complete new one and again I failed the test with the same inspector and the same values. I was so terrified about that and didn't know what I could do.
The next day I risked a further failed test. I asked an another Inspector if the failed test could cause of the cold engine. He told me, that it's a plausible reason. But he said that he pays attention to that very carefully, but cannot speak for all inspectors. He recommeded that I drive the car hot, so the catalytic converter is definitely hot.
So I had do that and pass the test with excellent values. So I'm very sure it was the inspector and a resentment about old cars.
So my car passed the inspection without defects.
Why I replaced an old catalytic converter with an old one? I was replacing the catalytic converter in my very exaggerated restauration/maintenance in precaution. It's very possible, that the catalytic converter was okay so I was risk to try out the old one before I was buying a new one.
The roadtrip with the car was from Berlin in Germany to Switzerland. It was about 2830km and more than 200l gasoline. The car was doing it excellent without any issues. I'm very happy about that very trusty car. Would do that again with my big whitey. He climbed the mountains as if they were hills.
It was very funny, me and my friend was shooting pictures of the landscapes in Switzerland. Very nice country.
If you are interested about the pictures I was shooting there, you can see them here

I hope my english is well enough for you to understand the content and it's anyway better than google translate, I guess.
