Video showing ATE Brake Booster seal replacement done inside the car
Hello everyone, wanted to show this video where I replace the leaking plunger seal of the Brake Booster without removing the Booster from the car. The video was done on a Volvo, which uses the same ATE Booster as several Mercedes models from around 2000-2014. Hope it helps everyone with this issue
I'm posting this also on the W204 forum since both models had this booster

Hopefully they've improved the seal in the updated brake booster. There's now a new PN for the entire assembly.
When mine started leaking (slight occasional hissing sound) I just jammed a pile of thick silicone grease into the seal. Now there's only a slight hiss when the pedal is being released, but I can live with that.

Packing with silicone grease can surely help limit the leak. Also good idea to put quality some silicone grease even if the seal has not started leaking - however I believe the main issue with leaking is less the lack of grease and more the fact that as you mention, the rubber in the seal gets too soft over the years, which obviously prevents a proper sealing given the quite important vacuum pressure it's submitted to.
