No. According to a query on the Audi official website, the Audi a655 generator problem is a problem that many car owners have responded to. The manufacturer has not provided a clear solution as of June 19, 2023. The Audi A6 is a luxury car produced by Audi, available in two models: sedan and station wagon.
Why is there an abnormal noise in the Audi A6L generator belt position?
If the engine starts cold, the engine sound will be louder, then become quieter after a minute. When the engine starts hot, the sound will be very low. It's normal. Because after parking, the engine oil will automatically flow back to the oil pan. During a cold start the next day, the engine oil will slowly return from the oil pan to the vicinity of the cylinder head. If it is a hot start, the oil in the engine is already in place, the lubrication and sealing are good and the noisewill naturally be weak. Therefore, the cold start sound will be louder, but its duration will not be very long, up to 2 minutes. If the engine roars for a long time, it should be checked as soon as possible at the service station.
If the engine makes a loud noise and grinds when starting from cold, check the engine oil usage. If poor quality gasoline is used, engine power will also decrease. deposits inside the engine will increase and engine noise will also increase.
If the motor has resonance, the motor will also make a loud noise. The squealing noise must be caused by the water pump belt or engine belt slipping after aging, or by the water pump impeller, water pump bearing or generator bearing and so on. other parts that have worn out due to lack of lubrication. This can also be due to friction betweenre the engine claw and bracket when the engine shakes strongly. If you check these items item by item, you can find out the cause.
So for a defect it is very important to know the cause because if the cause and location of the defect is found accurately then it amounts to more than half of the defect a been resolved. , so the car owner cannot ignore the importance of the cause.
Some time ago I wrote an article about a failure case of replacing the alternator belt of an Audi A6L with 140,000 kilometers. The cause of the failure was an abnormal noise in the position of the alternator belt. Unexpectedly, in less than a week, I saw this Audi A6 L again at the auto repair shop. Where did Audi come to repair it this time? Let's go as a group to find out more about the repair process for this Audi A6L!
As shown by the green arrow sIn the image below, the mileage of this Audi has exceeded 140,000 kilometers! I asked the auto repairer and learned that the reason why Audi came to the auto repair shop this time was that there was another abnormal noise in the position of the generator belt. This mainly involved replacing the tensioner roller and the bridge pulley which are closely linked. to the generator belt.
It turns out that when the auto repairer replaced the generator belt that made an abnormal noise last time, he suggested the car owner to replace the roller tensioner and the axle pulley together, but the car owner thought it was just the belt. There is an abnormal noise and needs to be replaced. These two wheels have no abnormal noise and do not want to be replaced.
Unexpectedly, less than a week later, the ownerThe car owner felt that there was a slight abnormality in the engine. If there is a noise, the mechanic will check that it is a problem with the tensioner. This time, the owner agreed to replace both wheels! As shown by the green arrow in the photo below, the mechanic removed the engine cover to make it easier to remove the generator belt!
At my request, the auto repairer took out the new tensioner roller and the axle pulley! Shown in the orange area in the image below, this is the generator belt deck pulley; shown in the green area is the generator belt tensioner pulley! The car repairman said that the thing making the abnormal noise was the tensioner wheel and that its deformation was quite serious!
After inspection, the auto mechanic found that it was relatively easy to remove both wheels from under the engine, so he removed the motor protectionur. As shown by the orange arrow in the image below, this is the old tensioner pulley; as shown by the green arrow, this is the bridge pulley;
Since the two wheels are held in place by a single screw, their removal is relatively easy. Soon the auto repairer removed the tensioner pulley. By comparing it with the old tensioner roller, you can clearly see the difference! As shown in the green area in the photo below, we can see that the old tensioner is badly deformed! The car owner was surprised when he saw this situation. He didn't expect the tensioner roller to be so deformed!
Compared with the old and new tensioners, the effective wheel surface is very different, and the old wheel surface is seriously worn! The auto repairer told the car owner that if the wheel is not replaced, the wheel could be damaged by the generator belt.At that time, the consequences will be more serious!
As shown in the orange area in the picture below, the auto repairer installed the bridge wheel! As shown by the green arrow, the auto mechanic is installing the tensioner! Their installation space is relatively small, so the installation speed of the auto repairer is a little slower!
After the auto mechanic installed the tensioner pulley and deck pulley, he began the final step, installing the generator belt! As shown by the arrow in the picture below, the auto mechanic is installing the generator belt!
After the auto mechanic installed the belt, the car owner started the engine. There was no longer any abnormal noise in the generator belt position and the problem was solved! Car owners lamented that when replacing the yardgenerator king, tensioner pulley and deck pulley linked to the belt should also be replaced. If I had known this, I would have replaced them together! Fortunately, it's not too late!
Finally, the auto repairer told me that not only did the tensioner need to be replaced when replacing the generator belt, but the parts closely related to the belt needed to be replaced. also be replaced when replacing the belt. timing belt. The tensioner pulley and deck pulley are designed to have a similar lifespan. If you replace only the problem part, the other part may soon have problems, making the repair time-consuming and laborious. loss!
Normal car maintenance involves not only repairing problem parts, but also a complete inspection and maintenance to nip problems in the bud! I hope thisThis repair case could be useful to our car owners!
