Mercedes S-class W220 door lock pressure leak. PSE system 

Hi, thank you for the video. There is no need to remove the window. The actuator is a major pain in the ass to remove though. I couldn't get it to detach from the door handle bracket so i took it out with the entire bracket. Really stupid designs.

I remember doing this when I was a MB Tech. I can only imagine what the dealer charged for these repairs.

That door lock unit cost around usd150/unit. Isn't it work on vacuum system?.

Damn i was gonna attempt this but its very hard to take door apart

congrats for the video and coaching ! I do have a similar problem in my car S350 2006, can you try to fix it ? How to best contact you ? Tks and best, Umberto

how much should this service cost? I replaced the pump in my 2006 s430 around Feb of this year, and it burned out again...so there is a leak somewhere, I suspect its the rear passenger door, because I noticed the door lock doesn't work and my front driver seat often acts up, it won't do the massage function anymore, and when you adjust the lumbar it does not stay. How much should I look to pay?

do u fix 05 s430 pse pump for central locking?

Is there an airbag in rear right door?

My left passenger door will not shut at all... do you have a video on what the issue may be?
