Message on the dash came up that coolant was low. I opened the hood and coolant seemed at an adequate level but I will top off to see if after that it comes up again. But upon opening the hood I saw what looked like leaking coolant. Can anyone tell me what they think is going on. I did the AEM update and have the extended warranty, would this be covered ?
Depends on the date of production for your GL350. Up to and including April 2014, BEVO spec is 326.0 (blue-green). After April 2014, BEVO spec is 326.6 which includes Zerex G-40 (pink).

Yes, that's correct. The spec changed mid-year. That's why I double checked the owners manual. I hope MBUSA didn't forget to update that manual as my model was made right around the changeover time!

Curious. I checked the manuals on the MB website and for 2014 and 2015 the recommendation was 326.0. For the 2016 manual the recommendation changes to a direction to check the BEVO operating fluid recommendations for 310.1, which is a generic spec.
BEVO 310.1 provides general information about all coolants used by MB. BEVO 325.x are concentrates. BEVO 326.x are pre-mixed, typically 50/50 but at least one spec is 40/60.
BEVO 320.1 provides is a table which specifies the applicable 325.x/326.x for each MB engine. Above you mention your manual requires 326.0; but 325.0 mixed 50/50 is the same thing.
