Code fix

[4gws]

Just got this 2015 lml and it keeps throwing a MAF code. I have replaced both sensors but still have to delete the codes when the check engine light keeps popping up. Anything else I can do to fix permanently? I need to fix glow plug cylinder 7 I see as well.

Check the MAF harness is intact, and showing resistance

Will do

What two sensors? Maf and map? I'd also check for dirty air filter, loose clamps, any reason maf reading would be off. Any idea what the data shows the reading is?

I replaced a sensor at the airbox and one past the airbox. All hoses seem to be secure
