How do I reset engine light on 2013 ML350. Have tightened

Customer Question

How do I reset engine light on 2013 ML350. Have tightened gas cap and need to know if this is what initiated its illumination.
JA: How has your mileage been lately? Has the car been starting normally?
Customer: Good and yes
JA: Are you hoping to fix this yourself? What have you tried so far?
Customer: Yes. As stated, told by son he read on gas cap door that improper tightening could cause engine light to come on. I unscrewed and checked o-ring on cap and retightened. Light did not go out. I am 100 miles from dealership.
JA: Anything else you think the mechanic should know?
Customer: About the light?
JA: OK. Got it. I'm sending you to a secure page on JustAnswer so you can place the $5 fully-refundable deposit now. While you're filling out that form, I'll tell the Mercedes Mechanic about your situation and then connect you two.

hi there,

im cam, a licenced diagnostic tech.

the only way to turn it off immediately, than it will need a scanner to access and turn reset it.

if you do not have one, most of the larger parts stores will scan and reset your code for free.
if you are miles away, than i would not be concerned as this will not affect running of the engine and once the computer goes through its own diagnostics and onces it sees a cirtain amount of iginition cycles and the problem is corrected, it will turn off by iteslf
