I'm thinking about buying a 240 or 300d sometime in the future, so I'm doing my research before hand to see what I'm in store for. You learn about a particular car and learn about it inside out (mine being Volvo 240's).
Just wanted to compliment you on the great video's you have. Very informational!

nice video! ive got a -83 240D but has no problem with the vacuum locks, just noticed a bit of delay for the rear left door (locks last) to go down but only like a few seconds.. they are as good as bulletproof these cars, gotta love´em!!

I have a 1998 ml320 and the door locks will not pop up with the key. The remote is lost. If you close the door it is always locked. To open the lock I have to insert the key and hold tension on it and open the door handlel. If the key is in the car and I close the door then I"m fu__ed. Got any ideas what it is. Are these vacuum actuated??

thank you

I've watched a couple of your videos. Awesome stuff. I don't own a MB right now but I want to get a 300 SD. I will definitely be getting some of your tools if I find the right 300. P.S. You would make a great auto shop teacher.

I run my w123 on used sunflower oil, there's no difference with gas-oil

Smoke machine is your best friend when I look at vac sys issues.

verry helpful
good video! question...when I lock the driver's door, the other door locks take about 2 seconds to go down. is this about the right amount of time?
btw, i have spent over well over $1000 with mercedessourcedotcom for parts and my 123 is now tip-top. the $'s i have saved and Kent's instrux manuals are VERY worth it, as i wouldn't have been able to afford to keep the car on the road as my daily driver otherwise. thanks kent!
