Customer: replied 7 months ago.
Just trying to trouble shoot y check engine came on. '07 ml350 4matic. Gas cap is sealed. Dipstick reads halfway down. Its 301 days past service d. It doesn't get much driving.its my brothers car so i don't know how many miles since last service.
Customer: replied 7 months ago.
It gets driven every 2 or 3 days just 10 miles.

ok got you, so do you have a scan tool or is there a local parts store close by? they read codes at no charge. without the code i cannot tell you even where to begin,

fuel caps are rarely the issue,

low oil will not set a check engine light

usually on the mL it can be fuel vapor leak, air pump,, lean fuel trim, or o2 sensor, but without the code it will be really hard to advise.

Expert:  Lou P. master tech replied 7 months ago.

so do you think you can go get the codes read? i think you can even rent the scan tool from the parts store for free you just put down a deposit. that way you dont have to listen to them try and sell you everything on their printout of the codes.

i have to step away for the moment i will check back soon.
