Do These Codes Equal New DMEs on My F02 750Li xDrive

[jeorgi_siris_7]

Well... had the Beast (2014 750Li xDrive F02) out on the wide open happily spiriting from a casino win, when all of a sudden felt like the engine was choking off for air while in Comfort+ Mode.

Took foot of the gas and switched into Sport 1 Mode, and it seemed fine. Went back into Comfort+ and gased it then it threw a DriveTrain error. Ended up having to use cruise to get home to be on the safe side.

Went to a shop for a diag, and the tech said he got the following codes:

[My Engine is the N63TU1]:

140001 - N63TU_L0 - DME2
-- Combustion misfires, several cylinders: Fuel injection is switched off

140004 - N63TU_L0 - DME2
-- Combustion misfires, several cylinders: Damaging exhaust gas

140010 - N63TU_L0 - DME2
140010 - N63TU_R0 - DME
-- Combustion misfires, several cylinders: detected (BOTH ARE SAME)

140101 - N63TU_L0 - DME2
-- Combustion misfire, cylinder 1: Fuel injection is switched off

140104 - N63TU_L0 - DME2
-- Combustion misfire, cylinder 1: Damaging exhaust gas

140401 - N63TU_L0 - DME2
-- Combustion misfire, cylinder 4: Fuel injection is switched off

140404 - N63TU_L0 - DME2
-- Combustion misfire, cylinder 4: Damaging exhaust gas

140501 - N63TU_L0 - DME2
-- Combustion misfire, cylinder 5: Fuel injection is switched off

140510 - N63TU_L0 - DME2
-- Combustion misfire, cylinder 5: detected


Based on this he suggested replacing plugs, which could use a change since I did them little more than a year ago.

Replace the coils, which I assume have never been changed since 2014 and I've never changed them.

Air filters as "Optional", which actually I just replaced less than a year ago.

Something called Run-Rite (fuel injector cleaner).

Then he spoke to someone else and came back and said both DME Modules!?! Another shop looked at it and said if my DMEs are capturing all these info, they are fine and other shop is looking a for 6,000+ pay day, as DMEs are expensive.

I do push the car on things like the PA Turnpike and other open mountain & flat areas... Keep it gased with either 93 or 94 fuel, and occasionally run the Berryman's B12 ChemTool for cleaning injectors if I am going Long-Distance travel drives. I stay up on oil changes as well: Castrol 5w30 High Performance Oil (US Formula).

I have a gut feeling that changing out the coils (gonna get the Dinan Coils) and new Bosch Double Plat Plugs are what is needed, along with the fuel cleaning.... Can anyone with a bit more experience guide and confirm this based on what I've provided?

If I have to bit the DME bullet then fine... but I sure don't want to. Thx everyone!
