Honestly, you are amazing to watch!!! You have a great way of explaining and very calm and collected while explaining, i could watch you all day!! I jusy ordered those vacuum hoes from mercedes, it was cheaper than online. Im having a little bit of engine shaking, i fixed the valve covers since they where leaking, then changed crankshaft position sensor, maf sensor... Cleaned the camshaft position sensor but looks like i need to chage it, and Map sensor looks original from 2004 so might change that one too.... I hope that fixes the shaking.... I have brand new motor and trans mounts so its not those.... Wish i had your patience to be able to film and explain Hahaha, keep it up!

@@L35inColorado Good morning L35. I need your advice please. I own a 2004 ML500 that hasn't been started in 6 years. I want to start using it. I don't want to just charge the battery and turn the key. I want to lubricate the bearings first. I know I can't prime the oil pump manually so I thought I should change the oil and filter but also overfill the oil by double or more. Than I could turn the car over by hand a few times; then drain the excess oil and wait a day and then start the car. Perhaps there is some access like the oil filter housing unit or the oil expansion plug that I could remove and observe the oil level with my borescope? I was thinking about removing the oil pan and squirting oil but that actually could end up being a more time intensive job than I have time for at the moment. Many thanks for any thoughts you can offer. Steve M.

Always love your vids! Super well explained and shown. So glad i came across this vid, as not that long ago i replaced my map sensor (W211 E500) and the hose behind it was pretty well rotted at the end and all stretched out.. I was aware prior about that other scary vacuum hose, the one you mentioned not to touch. Yup thats the nightmare one if it dislodges or leaks where it goes into intake manifold. Massive scary job to fix something so stupid. Love my Benz but some ideas Mercedes came up with are absolutley horrid. Biodegradable wire insulation being one of them 😬🤬. Well i was so worried when i spliced in a small section of hose for the map nipple thinking maybe it was the same hose as the nightmare one. Praying it wasnt dry rotted alway back. Had me worried. Much relieved now seeing your vid. Now I'll go back in and just replace the entire map hose and secondary air pump switchover solenoid hose too. Thanx again for the great vid 👍👍

[@L35inColorado]

Oh man, I know the feeling! Yes, I don't understand why MB made some of the decisions they did, and we've had major issues with the wire insulation apparently being so "tasty" that mice can't resist it! haha : ) Thanks for watching!

Definitely not putting my trust in old rubber hoses & sensors after all the trouble I went through rebuilding her . I just need new fuel injectors before I can fire her up again , a few got stuck open after cleaning them in ultrasonic cleaner but after a few taps they closed but leaks , can’t trust them either !

@@L35inColoradohey there . Have you ever encountered code p2004 ? . I’m assuming is some external issue because i recently rebuilt my intake manifold for my w163 ml500 & I didn’t replace the vacuum actuated solenoid on it during my engine rebuild , so far the rebuild has 4k miles and have had no issues, just this p2004 code . I replaced just about everything except for that specific part lol .
