MES will probably not see a coil problem. You would have to work it out from other symptoms.
There are many parameters that affect fuel consumption - air filter - air flow measurement - engine temperature and anything onwards from there. All you can do is get the readings and look for discrepancies.
I don't know if the MES free version will give what you need. Try posting in the relevant forum section.
