2011 x5 35d with 10 Fault Codes

Problem with ignoring CELs and codes is that it can make diagnoses so much more difficult.

The MAF sensor also should include an intake air temp sensor inside it... all wires/connections/harnesses good?

Cleaning the MAF is on my list of things to do this weekend. Hopefully that takes care of those 2. It's nice to know the IAT is inside the MAF

A dirt maf will NOT also cause an IAT issue....

The commonality is the wires on the maf itself...so a bad connection or rodent damage would cause both errors.

Speaking of...any signs of rodents nesting?

No signs of rodent nesting under the hood, but there are rats in the neighborhood which doesn't mean one didn't chew at some wiring while scavenging for nesting materials. I'll add that on my list for this weekend.
