When chatting with my riders in the group, I talked about the frequent cases of Passat’s water board cracking in the sun.
If the situation is in bad condition, it may have fallen off in the sun, and the owner has not even noticed it.
Because they are both plastic parts, there are also drivers who report that the seam of the sunroof tape is tilted.
I usually use sunroof frequently when I use my car, especially when opening at a small angle, there will be abnormal noises on bumpy roads.
After checking that my car also had the sunroof strips tilted, I drove to 4S to prepare a claim for the sunroof strips and check the bumps of the sunroof.
Although sunlights are used frequently, not every gear is used.
After the inspection, the master told me that if the rubber strip was to be replaced, the effect after construction might not be as good as when the original car was delivered from the factory. He even encountered leaks after replacement, so he gave up the claim.
After inspection, the master also said that my skylight track was a little dirty. It had not been cleaned and maintained for a long time.
In fact, I haven’t cleaned it since I bought a car. The master checked whether the drain outlet is blocked during daily maintenance.
So I simply did a sunroof maintenance operation.
According to the recommendations of the maintenance manual, in addition to checking the drainage function, it is necessary to carry out cleaning and grease maintenance.
The maintenance kit from the 4S warehouse looks like it was bought outside, not like an original accessory.
It has many functions. In addition to cleaning and lubrication, the anti-aging adhesive strip also has a noise reduction function.
The scope of use is not just the sunroof. After the rear sunroof was maintained, I also applied the remaining material to the door hinge.
The maintenance instructions are listed in quite detail. In fact, this set can be operated by yourself if you have conditions at home and if you have hands-on skills.
The clean sunroof track still lacks brightness and is very dim
After touching the detergent, the brightness of the gel was restored immediately
The air gun blows down the skylight drain hole to blow out the impurities remaining in the drain pipe
When the water outlet is near the tire fender, you can observe the removal situation
Finally, apply lubrication grease. If you do it yourself, you need a handful of silicone qiang
Put on the sunroof with lubricating grease and try again several times to see if there is any abnormality in opening and closing.
Taking advantage of the fact that the master had not used up some grease after the construction, I put some on the door hinge myself. If the door becomes too twisted to open and close, it should be improved.
Finally, I used a computer to check and found that there were no abnormalities after the data was checked.
Summary:
In normal maintenance, we should only check the water outlet at the drainage outlet. Some of them are even ignored without inspection. As the saying goes, it will not be damaged and will not be repaired. If you can, you can save. But in fact, after cleaning and maintaining the track and drainage holes together, not only will the appearance be improved, but also the aging of plastics and rubber strips be alleviated. It should also have some effect in function. When the car passes through bumpy roads, if it is cushioned and comfortable, it will not produce abnormal noises. As for how to maintain it, I think those who are capable can shop online for products and construction work according to the post, and the operation is not very difficult.
