Hello , I hope I’m in the right part of the forum, I would like to contact the Lima and electrics experts. I have today developed a Bosch LiMa for testing and clamped it into a vice for the test setup. I had previously cleaned all the contacts and removed the windings with Caramba brake cleaner from oxide and corrosion. I always checked with the beeper of the multimeter whether the contacts have connected again. So the controller again in d test lamp on D+ from the controller (two small pins, one probably without function?) and B+ from the Lima on B+ from the battery and B- from the battery on the vice by bridge cable. test lamp also lit. now I turned the Lima by drilling machine and wanted to see what happened. At a certain speed the test lamp then went out, that should usually mean that the LiMA starts to generate power, but when I started the drill from the test lamp did not work anymore and I can no longer get a signal with the through-checker when I hold the D+ pins of the controller and the pathogen contacts or the connection to the small screw. Can it be that due to the vibration of the drilling machine the crocodile clamp has come to both pins at the D+ connector and has caused such a short circuit or does this have a reason? I am just about to understand how the whole thing works and stand j on the hose why I can’t get the test lamp to run anymore. Thanks lg midnight blue79

Halli Hello, I’ve been looking for a few hours but I didn’t find anything really interesting! I have a 12V Power Bull car battery and a microchip controlled charger! Unfortunately, this is not possible because the battery is probably deep discharge, now my real question : Does it bring me now what the battery a quarter of an hour with a starter cable to hang on to the battery of my running car and after that try again? If yes I buy today still en Starterk abel! Achja and do I have to screw up the battery when charging? There is nothing to be found with the manufacturer, thank you already in advance!

Since in my Alhambra there is still G11 inside I have once read into the problem of the cooling fluids. One must not mix G11 with G12, but with G12+ or later already. The G13 is supposedly not on glycol basis but something else. Since I rely on a silicate-free glycol-based KF on my motorcycle I wonder how the liquids differ in how much heat they can transport away. But I have not found any values, neither a NORM nor Is it blind? EDIT: There are such miracle remedies as “engine Ice” which supposedly can remove more heat from the engine. Will the engine be cooler? (Not that I would need it, my two motors here have not been very hotly constructed)

Hello! I would have a question… The air conditioning (Climatronic) in my Octavia 1U was switched off for quite a year now. The reason was a leak in the climate condensator. I have changed this now (including dryer). My question now: How do I best go about putting the system back into operation? My mechanic only has a filling device there with which he could fill the system normally. And then I could just turn on the air conditioning in the car. Achster Weg. However, I have also read things about cleaning, rinsing, disinfecting, etc. the air conditioning system. That would be one thing, should I have something done? Do I have to go to the specialist plant for this? What about the oil that should lubricate the bearings of the compressor? Does that have to be filled in extra? And then because of the compressor: could be that the bearings are a little tight now, after a year. There would be good to turn it slowly and loosen it. But if I had the climate on switch, then the compressor blows directly in. Is there a possibility? Thank you!

First hello to everyone, am new here, therefore I have no idea whether I have sorted my request thematically correctly. But now directly to the matter. I have now extensively informed myself on the Internet and found out a lot about all-round lights and front flashes. Blue light and yellow light fall away anyway, red light and green light seem to be generally forbidden in DE and with white light unfortunately I found no unambiguous information. Now my question is: Would theoretically be a cyan colored or turquoise front flasher + all-round light legal? In fact, this is neither blue, nor green, as these are their own shades and therefore do not have to be registered or regulated by law, right? I’m not interested in spending myself as an emergency vehicle or something like that on this point either. I just want to be able to point out to other road users that something might not be right. Both behind me driving vehicles and vehicles in front of me. I have it in front of me. d, after I am a frequent driver, unfortunately more than often enough experienced that enormous danger situations of all kinds have arisen, which were partly in their intensity so enormous that a simple brake/warning light was not sufficient as a hint. These only in the rarest cases traffic jams, but nevertheless sudden accidents, which happen directly before or behind you. Likewise, people who are of the opinion to drive on the highway in front of you, one to 20 km/h slow down To have n and then make it impossible for you to overtake them, because at home they are probably constantly only finished by the woman, have nothing to say or maybe are simply completely alone, what do I know what these beings see as a “justified reason”. Anyway, there have been such situations several times on the route that I drive, and just at night (wedding of such minor mediated) a cyan-colored or turquoise light could warn the traffic behind me and at the same time scare the serious traffic danger in front of me and thus lead to the ending of the serious danger situation. Likewise, especially for such cases, it would be good to know whether auditory signals are generally forbidden, or whether this depends on sound, melody or completely different points, also mentioned points, if present, would be good to know. Thank you in advance for the answers! Lg, Kirschi

Hello guys, need your expert advice. We wanted to go on vacation on Saturday and therefore have another air conditioning service and oil change today. Peugeot 306 Diesel HDI 2.0 After the service the climate no longer works. If you turn it on, the speed in the stationary gas is slightly lowered at regular intervals (about 3 seconds) and again up, If you drive you even feel a delay as if you were going on the brake for a short time. a service is fixed? That’s what’s ever heard. Maybe what about the electrics? Thank you cool, by the way, it doesn’t do anymore

Hello and Merry Christmas on everyone’s part, we went on vacation a few days ago and the wind noises with the roof box bother me pretty much. I voluntarily do not drive more than 120km/h, although I would not drive faster than 140 without loud wind noises. I have original Mercedes basic rack for a CLS C218 and an original Mercedes roof box with 450l, but an old model, I guess 10-15 years old. The T-nut is covered with a rubber strip and for the screw I have drilled holes into the rubber strip. As far as I can remember, wind noises were only noticeable with basic beams when I got the roof box. I don’t know now whether the basic beams are the problem or whether the roof box is even worse. It’s not a whistle, but just loud. Make users write that the wind noises are very well bearable or hardly noticeable up to a certain speed. In the appendix are pictures like me the Dac From Mercedes there is now a new roof box, similar to the Thule Motion. Manufacturer of the new MB roof box is also Thule. The new box is flat below, which is why it could be significantly better in terms of noise. However, the one type of claws that grip around the base beams. These are in turn additional interference contours in the wind. Are there any tips regarding position of the roof box or better products?

Hello. An employee at a contract workshop said that the car was also well maintained if the service was made at another contract workshop OR even at a free workshop, so long it is guaranteed that the manufacturer’s specifications are met and that this can be verified. Google says something else, namely that when the service is done in a free workshop, the car is no longer considered as a staple. Does anyone know this more precisely?

Good afternoon, I have a theoretical question regarding the cooling system of an excavator (similar to the Japanese cooling system car) Key data: -coolant cooler with cap (lower & higher pressure valve) -storage tank whose position is below the cooler -storage tank has an overflow hose and a hose to the cooler cap (cooler) Is it possible that if the coolant level in the cooler is low (due to air in the cooling system or poor filling) and the pressure rises, so that the pressure relief valve opens in the lid -> air in the hose (because air is located in the top of the collection box) comes in the direction of the storage tank. Then in the hose there would be only air (no more coolant) so that a resuscitation can no longer work and thus no coolant can flow from the storage tank into the cooler? Is this possible in theory or must already lack a lot of coolant in the cooler or is it never possible? the case that in the collection box of the cooler so much air collects in engine operation, because the coolant actually circulates? I hope I understand my special question. I am happy to answer.

Hi, who doesn’t know the statement: If the airbag control light is lit, the whole system is switched off. I’ve heard of workshop masters, but I can’t believe it. Example: Vehicle has 6 airbags and the side airbag has a fault (Zündstromkreis hohhmig). Do the remaining 5 airbags trigger in the event of an accident? Should the software be prevented, that borders already on negligent killing. Example: Driver shifts the driver’s seat and thereby interrupts the V binding to the side airbag, 5 minutes later he drives against a tree and dies because the driver airbag did not work because of the fault. That it is of course so in case of sensor errors, is clear, therefore explicitly related to “interruption ignition circuit” of individual airbags. Does one know more? Thanks. PS. No, I don’t want to try it. Greeting Metalhead
