Dear engine talk community, I did a test drive with an Audi A3 today (https://suchen.mobile.de/vehicles/details.html?id=377550217). It was all tip top, I’m generally thrilled. Except that on the inside of the oil cover was this white slime. Photo: https://i.imgur.com/k8hh9P9.jpg (or attachment) There was also a relatively large amount of white smoke/Qualm out of the exhaust (but only at the beginning). I approached the seller and he pushed it to that that the car came out of the exhaust (but only at the beginning). I find the price of 20980 € also relatively cheap compared to other Audi A3 vehicles with similar data (kilometre level, year of construction, equipment) on mobile.de. That makes me a little suspicious. However, I am a car noob and wanted to ask about this forum, in which I was so far only silent reader. How do you value the white surface on the photo (link above or also in the appendix)? Look forward to your input, thank you already!

hello and good evening, have a question about the possibilities to get a car with long translation. Here I have read threads from GOLF – which offer the option to translate the 5th gear longer. With a reasonable effort. Question: so: translate longer : which cars are particularly good – have you experienced – possibly also tables or diagrams of standard translations.

And that’s exactly what I want to know. I’ve already read a lot about the KW camp not to break. But if, how does it sound? Can you imagine that through a defective/unbalance flywheel, the KW camps can break? In the long run.

In almost every older car (about 10-20 years) there is always a certain smell. By this I mean now not the classics like dog or cigarette, but simply the car smell, which even cars have never been smoked in and in which a dog has never been driven. In summer in heat the smell comes most intensely when you enter fresh. Are these any material evaporations that become active only after years? The interior filter can actually auc h not be when the smell is the most intense in the car. I am not concerned with the elimination of the smell, I want to understand where it comes from. Can someone explain the smell technically?

Moin. My distribution gearbox died without obvious reasons. Although I only drive on paved roads and at moderate speed with my Discovery3. Basically, I drive with prescribed air pressure. However, the air pressure on the rear wheels is often about 0.2 bar higher than the table value. Also, the profile on the rear wheels is higher. Thus, I ultimately drive at different speeds at the central differential in the distribution gearbox. Sometimes up to 1,000km Can such small rotary differentials permanently destroy the central differential?

Hello, as is well known, electric cars and burners have a “starter battery”. I would like to know how much watt you can take from the above-mentioned starter battery in the operation of the vehicle. My wish would be 2kW “safe continuous power”, possible peaks up to 3.5kW. Would that be possible with a suitable voltage converter 12v/230V which is connected directly to the battery? With the burner I know that for example at traffic light phases of the generator the battery is not enough nac What about electric cars? So again: 2kw of continuous power up to 3.5kW tips would be desired. Is this possible with current vehicles, whether electric or burner? Although I am layman, I could imagine that the electric advantages would be, since the battery from the batteries will probably be supplied permanently regardless of the speed. Thank you

Maybe the question is a bit “female” and “blond”, maybe both, but I’m really at a loss. At the moment it’s still winter and as a short distance driver I thought that one or woman could do something for his car and the battery care. So the much recommended CTEK MXS 5.0 bought. Well, now I’m faced with the problem that the battery is built in such a way that the poles of the battery are not exposed, i.e. you can’t attach terminals of the charger there (see photo) . In the case of the negative pole this could still be painful, since the clamp should not be on anyway according to the instructions, but on the vehicle body (which is also difficult, because there are no unpainted parts in the range of the cable). What do you do now? Just clamp to the screws or nuts of the fastening? Does someone have a piece of advice, as with such a built-in battery to proceed?

Hello together, hope someone can give me a tip for a car relay. I have a button contact and want to be able to switch between two circuits back and forth. Either the one circle is active or the other one is never at the same time. The last state should be maintained until the next touch signal is similar to this old power shock relay for the stairwell where a wheel is switched on and switched at the output alternately 0 -> 1 -> 0 -> 1 etc. My Switching contact should have 3 connections that I can always switch contact A to B or A to C through the button. Does anyone have an idea which relay is suitable for this?

Hello It’s about a Sprinter Diesel/Hybrid of the latest generation and this vehicle is specially designed for use in medical transport and intensive transport. Among the special features is that the vehicle will have an additional consumer with about 5kW on board and is operated around 8 to 9 hours, but has no possibility of charging at a power outlet. As is generally known, this will not be possible over the Lima. tzgeneratoren / Unterflurgeneratoren aus or has someone a different idea? Unfortunately, most run only at 3000 revolutions in the required 220 volt range, which makes the thing difficult. Therefore, the devices known to me are eliminated. A generator solution based on diesel is eliminated, because of the noise (yes also with Panda generators) and emissions. In addition, the solution would not be really practical, since actually “one engine” is already on board. Maybe who has a tip! EDIT: 5kW not 5000 kW

Hello motor talk community, I am very interested in cars, however, my knowledge in this field is quite limited. I would like to learn more about it in order to talk more profoundly and to develop a deeper understanding of cars. Can you please give me some tips on how to effectively and systematically acquire car knowledge? Maybe you can recommend me which books, websites, videos or forums are especially helpful to basic knowledge about cars, their Are there special resources that are particularly suitable for beginners? I would also appreciate advice on how to interact with like-minded people and learn from their experiences. Are there local meeting places or online communities that are recommended for car lovers and newcomers? I am happy about every support and thank you in advance for your help!
