  • Determining braking TÜV

    Moin, my girlfriend just dropped the HU with her small car. The car reached the following measured values: front: li 150, re 160 rear: li 70, re 40 total braking power: 37% I calculated this time and did not get this brake value. Approach: F=m*g The brake values are in daN therefore 10N. So the calculation for the braking power in %: x=brake force/weight force x=(1500N+1600N+700N+400N)/(700kg*9.91m/s2) = 0.61 = 61% Clear, the deviation from right back to left is behind with 57% much too high, but the overall braking performance should be right or not? Does the repair effort make a bigger difference. So can someone explain this to me? Thank you Dennis

  • Audi A2 – Advanced lightweight construction technology? – And today?

    Hello, I asked myself several times, since we had an A2 in the family, why Audi could achieve such a low weight for a fully grown car (one observes the space in the interior). Sure, the A2 had an aluminium body. So far so good. But the new i3 is heavier than the expired Audi A2 1.2 TDI. Even with the battery of the i3 the Audi would have been lighter.Weight A2 1.2 TDI (without driver) – 855kg weight i3 without REX (without driver) 1195 kg battery weight of the i3 – 230kg So why is the i3 heavier, despite the carbon fiber passenger cell? Carbon is about 50% lighter than aluminium. Is it because the thermoplastic planking weighs extra weight for the i3? It is also important to remember that the engine and the gearbox weighs significantly more than the electric motor from the BMW. Since all the auxiliary units from the Audi bring a lot of weight with them. It is clear to me that the carbon is not the same as carbon and that there are also differences in aluminium. Audi simply did a job that was too good as a lightweight world champion at the time, or why is the i3 heavier now?

  • Small capacitor question

    How does the fire department know that a condenser is not installed in the car?? Do the fire department have to jam both? Battery and condenser??

  • Car purchase

    Hello together, first praise to the really good community here. Now to my concern. I start an education in August after Abi and look for a new car. Budget approx. <900€. So I prefer to stay under 9000. I want either a nice limousine or a fast sports coupe/cabrio. I then have to drive about 50km. daily. The majority of the route is federal road, on which also often LkW's and tractors are on the road. Therefore the car should have some power so that a züzü For me, the acceleration is more important than a high maximum speed. For the equipment: leather seats, bright, and an integrated navigator, looks simply noble, cruise control, etc., but can do without things. The limousine should have automatic. I like Audi A4/A6 from 2005, where not only the rings silver are bordered on the front. And the A4 convertible is also very chic, but should probably swallow quite a lot?? If you need even more information says Eid Oh and I would also like to have one or more reasons why this car. Mfg

  • Aral Benzin at Sportster 2017

    Servas- I’m just making my sportster (Ez 2016 is but model 2017). I now have 5200 km, of which about 95% with Aral Super lead-free. For the few km very strong deposits in the combustion room and also already in the intake area or on the valves. So nothing increased but for the few meters already crass I find. At least up to the combustion room I expected new value. Far away from it! I thought something good but with the result I refuel from now on cheap. Or I try a lot t with Shell. Same great propaganda. Let’s see… What experiences do you have? Greetings Michi

  • Tyre choice Z900

    Hello together, I’m looking for a good tyre for my Z900 as shown on the title. I don’t know myself very well because I’m relatively new and that’s going to be my first tyre purchase. I’m actually looking for the best possible compromise between grip and durability. So it doesn’t have to be a high performance tire, but it should still be able to take a curve with a little momentum. After some research I came across the Diablo Rosso 3, someone can say something. or do you perhaps have much better or cheaper tips? Cost-effective is not meant to pay as little as possible, but rather so that I don’t want to pay unnecessarily much. Perhaps as a hint, the first tire is the Dunlop D214 Z and I’m quite satisfied with that. (I think at least, but I don’t have any benchmarks, just a little more longevity I would like) Thank you and LG

  • Curricious problem: battery is not charged

    Servus people, maybe one of you can help me! My KLR650 got TÜV 4 days ago and is already standing still. After I could flex for about a quarter of an hour without any problems, it went out during the ride. Keys turned around again but indicator lamp Neutral does not glow. E starter does not work either. Pushing is relatively easy, then it also works well. However, from there on the light did not go right. Quite dark and flickering. If you slow down, the Light brighter, also when blinking. Also very funny: temperature indicator and rev indicator only go when the light is switched on during the ride. When the light is switched off nothing is displayed. New battery (full) installed and new indicator rear with load independent relay. While doing so maybe something wrong connected ? E starter and light also a few days later does not work. Push no problem. Someone an idea ? Gracias!

  • Complete system Z900?

    Hello together, I have a Z900 and wanted to ask you a question, do you know or are there any legal exhaust complete systems that might bring the sound over a little more satter than it can the original system? On the Internet there are some providers but how do I recognize whether the are legal? What I really don’t want is that I suddenly get the further drive in the middle of the Black Forest, then I prefer to stay with the original system with Euro 4 “Sound”. I hope you can m I’m helping!

  • Missing trailer load Ford F150… what to do? Too low maximum ZGG?

    Hey, I wanted to get a pedestal with ABE for max 3.5 ton of trailer load on eBay, as I would like to take the class BE driver’s license soon. Again for safety reasons in the vehicle papers and what do I have to see there? Under O.1 and O.2 absolutely nothing is registered. Today immediately with the local TÜV examiner on the phone and he said that I should buy the AHK anyway. And then with this + the values of Ford USA come to him and then one can enter a pedestal afterwards It was very friendly, but somehow I’m uncomfortable to buy this thing if I don’t have any certainty that I can really pull the truck. In addition, he said that he can’t enter more than the maximum permissible weight of the F150. There’s about ~2,83To in my bill. My emptiness already weighs ~2,6To. How can that be? That’s not true, that I can only charge just under 230kg in the debris? I’d like to have the 3,5To trailer load. With my combination si nd according to Ford USA 7700lb possible, have even the tow package as factory option. What is your recommendation? Can you do anything at the maximum permissible total weight? Greeting, Johannes
