Is the Sunroof Rattle a Common Issue in the Magotan?
4 Answers
Sunroof rattle is not a common issue in the Magotan. The causes of sunroof rattles vary, but they can usually be resolved by tightening screws, cleaning, and applying specialized lubricants. Taking the 2020 Magotan as an example, it belongs to the mid-size car category with the following dimensions: length 4865mm, width 1832mm, height 1471mm, and a wheelbase of 2871mm. The curb weight is 1445kg. The 2020 Magotan features a front MacPherson strut independent suspension and a rear multi-link independent suspension. It is equipped with a 1.4L turbocharged engine, delivering a maximum horsepower of 150PS, a maximum power of 110kW, and a maximum torque of 250Nm, paired with a 7-speed dual-clutch transmission.
My car is indeed the 2018 Magotan, and the sunroof really creaks whenever driving on bumpy roads. Several fellow owners have complained about this issue too. There are mainly two reasons: first, the aging rubber seals rubbing against the frame, especially noticeable in northern winters when low temperatures make the rubber harder, causing harsh friction noises. Second, there are slight tolerances between the roof panel and sunroof frame during assembly, which over time create gaps leading to resonance. Last week, I applied special lubricant at the 4S shop and it improved significantly. The technician said this is a common issue with this type of frameless panoramic sunroof, and regular cleaning of the sliding tracks and replacing the rubber seals can help alleviate it. It's advised not to disassemble the roof lining randomly, as improper handling may lead to even more rattles.
With seven years of quality inspection experience at a 4S shop, the Magotan ranks among the top three in the case database for sunroof rattles in German cars. Assembly line workers may not have properly adjusted the slide rail base, causing excessive stress on the frame. A typical symptom: no noise when opening the sunroof, but a squeaking sound when going over speed bumps after closing it. This is due to the deformation of the guide rail stopper from compression. Although Volkswagen's aluminum alloy frame has strong rigidity, its buffer design is insufficient. The new solution involves embedding 3mm soft rubber spacers at the roof panel seams, but this requires removing the headliner. Recently, it was also discovered that blocked drainage holes causing corrosion of the motor bracket can also lead to rattling.
As a mechanic, I recommend performing three self-checks first: open the sunroof and wipe clean the sand and mud on both sides of the tracks with wet wipes; spray WD-40 lubricant into the track grooves, but avoid spraying it onto the rubber seals; check if the sealing rubber strips at the four corners of the glass have come unglued. Last week, I fixed a Magotan with 30,000 kilometers on it—the noise was caused by sand grinding against metal pieces in the tracks, and it became quiet immediately after cleaning. A reminder: cars with modified audio systems or dismantled headliners are particularly prone to rattling noises due to increased play. This issue isn’t a major fault, but it can be quite annoying to hear.
