X5M New codes 2D09 2D4b

Starting getting these two codes recently. Even clearing the codes does not help as they immediately come back. Generally when goosing it.
I reset the throttle body by pressing the gas for 30 seconds with engine off and in ignition position 3, then waiting 30 seconds. The codes go away and it it is fine until I get on it again and the codes come back, then limp mode. It will go WOT but once I let off, there they are.

All of this occurred after I replaced the Bosch coils with Eldor coils as I lost 5 of the ‘new’ Bosch coils. My idle is also not as smooth. All plugs checked. #8 cylinder had a bad plug from a coil failure, replaced it, so far good. Plug looks almost new after 150 miles, so not an engine issue.

These do not seem to be common error codes as I did not see them come up for any E70.

So action plan:

1. Check all vacuum hoses as I heard this can cause throttle errors. Update - I do not see any obvious issues with vacuum.
2. Replace throttle bodies, cheap new. Perhaps give the butterfly arm a grind
3. Accelerator pedal
4. Throttle harness. I know these affected earlier E70s, not sure about 2010 and up.

Any other thoughts?

As a followup, as often times folks post issues, get it fixed, and then their gone with no update. I replaced the accelerator pedal with a brand new unit, unplugged batter for 30 minutes, reconnected battery, initiatived throttle body adaptions, and so far 200 miles later no problems.
