Yes the Curt trailer hitch # C13117 will fit your 2013 Mercedes ML 350 BlueTec diesel model! The only exclusion is that it will not fit models that have the Active Curve System.

If you plan on doing some towing I recommend etrailer ball mount kit # 989900. It comes with 2 ball mounts; one with a 3/4 inch rise or 2 inch drop and one with a 2-3/4 inch rise or 4 inch drop. It also includes a 1-7/8 inch ball, 2 inch ball, hitch pin with clip, and a storage bag.

If the ball mount kit does not have the right rise or drop to tow the trailer level, use the link I have included that explains how to measure to choose a ball mount to tow the trailer level.

And for trailer wiring you can use # 119250KIT to add a 4-Way flat connector to the rear of the vehicle.

If you want to use the hitch for a bike rack or cargo carrier in addition to any towing I recommend Draw-Tite hitch # 76141 instead of the Curt hitch. This is because with the Curt hitch Curt requires the use of a stabilization strap # 18050 for non-trailer loads for their warranty. The Draw-Tite hitch does not have this requirement.

Expert Reply (on your website) from your Michael H regarding "Yes the Curt trailer hitch # C13117 will fit your 2013 Mercedes ML 350 BlueTec diesel model!" But your online catalog does not show a listing for this part number for my vehicle, only shows a Curt #C13411 but says "Does not fit vehicles with a diesel engine". I need hitch for Mercedes 350ML BlueTec diesel model. Will this #C13117 definitly work? Modifications to vehicle required? What is price? How do I find this product on your website? Thanks

@Rob Hello Rob, that must have been an older answer, because sadly the Curt # C13117 hitch is no longer available. We sold our last one back in late 2020. At this time the Curt # C13411 is the only hitch available for the 2013 MB ML 350 but it will not fit the Diesel models.
