Mercedes W212 | Removing Rust & Center Console Repair

Removing rust on the tow hitch (code 550 trailer coupling) with rust remover. I believe is som kind of phosphoric acid. Also had some issue with the center console compartment, the lid did make some weird noise. The old credit card from previously owner left there was the issue for that. I believe this kind of problem with center console lid are really common. I did not include to much details as part-nr in this video. Check my channel I have another more detailed video for console repair.
