Mercedes ML350 bluetec sputter misfire

15 Nov 2019 •
Hi I have an 2013 MB ML350 Bluetec diesel suv with 50k miles. It misfires sputters at 1600 to 1800 rpm. I have since done an oil change. Changed engine air filter. Run a diesel Stanadyne additive and changed the fuel filter. Did a leak test on the turbo and air intake and replaced the o rings. Also did an ecu reset. Mass air flow sensors were changed not long ago. None of this has solved my problem. No engine light is coming on. Anyone else have this problem or a solution? Thanks in advance.

How connect my phone for music

Hello, I would like to know how I can connect my phone to be able to read Spotify, youtube or others. I found a port in the glove box, but I don't know if I can use any adapter to have a Bluetooth or jack output. It's a 2008 ML 320. <img alt="Plug" data-entity-type="file" data-entity-uuid="5f22cbf6-68bc-4dbc-babb-099b21476cf5" src="…; />

ML 430 Differential

15 Nov 2019 •
I was changing the ball joints on my ML 430 and ran into 2 issues. The first is I ended up taking out both transaxles at the same time and now it seems a rod has dropped down in the center of the differential so the transaxles will not go in far enough. How can I fix this? The second question is the reason for the first. The passenger side upper ball joint bolt was tilted over at about a 30 degree angle. This is why I was changing them. When I attempted to reassemble that side, it was very difficult to get the top control arm connected.

Mercedes ML350 A/C Issues

15 Nov 2019 •
My wife has a 2005 Mercedes ML350 (I believe it's a W163) and her A/C is blowing hot air. I'll save you the incredibly long troubleshooting background, and instead will tell you all of the pertinent information of things I've done and parts I've changed. 1)Replaced pressure sensor. 2)Replaced expansion valve. 3)Replaced cabin air filter. 4)Hooked up to a buddy's computer and found the compressor to be bad, so it has now been replaced as well. 5)After compressor install I hooked it up to an AC machine and ran a 30 minute vacuum.
