Warehouse damage of the Wapu or Lima? Hello, from the area of the V-belt there is a loudening klakkern and looping. In two workshops it could not be identified. In addition, a loudening howling/circle/squeaking occurs from time to time during motorway rides, which can possibly also come from a defective wheel bearing, which will soon be replaced (see thread) A removal of V-belts/squeeze rolls is to take place etc. But this is already with corresponding costs. The workshops want to earn money and offer the complete program immediately, if you can not make any suggestions for tests yourself. My question: Can you not test the function of the Wapu and the Lima without building something up. Have googled, but because I have no idea, here are questions: 1. Couldn’t you just pull off / disconnect the cables of the Lima. If the noise then should not be present, can it not be the Lima?? Or in the stand all electrisc Should the noise then be louder? The voltage of the battery is ok, by the way. Shouldn’t a defective Lima also be noticeable due to poor functioning or failure of the electrical system? Also no warning light available. 2. The water pump has been changed after a timing belt crack at the last owner only in Dec. last year, but a cheap part for 21 €. The car was then no longer driven before I bought it at the end of May. Since c a. 4000 km. Is the probability not very low that a Wapu should be defective during this period? Should not a bearing damage of the Wapu also be noticeable by coolant loss, which is not the case? Or by water stains under the car?? Can one remove the belts and check by where the noise comes from. If it is not there without belts, then it is not the Wapu, right? If one turns Wapu with the hand, a grinding sound would have to be heard s a, right? Can you locate the noise with a screwdriver, listen to the parts on it and hear where it is loudest? Where is the wapu at the Twingo?? Is it right that you can repair the bearings of the Lima at the Twingo? Perhaps it should also be the climate compressor. Should the noise then be louder in the running climate? Perhaps also the belts/clamp rolls. How can you check this? Thank you for the help! The upcoming repairs will be expensive (wheel bearings etc.) LG Dawso n
