Hello everyone! I have a problem: When folding the rear seat I noticed that the “carpet”, or this patchy felt cover under the seat of the rear seat behind the driver’s seat water has entered. This felt was totally soaked. Under the felt is such a lid in the sheet metal with four screws, which practically goes into the vehicle floor. Does anyone know what it is for? I have already screwed it up, there is also ́ne seal, which certainly looked something “kneaded”? Ka Did any of you ever have such a case? Where do you think water could penetrate under the back seat from outside? Thank you for your help! Best regards Michael
