ESP Malfunction. Car won't start.
Car was stored for winter.
Trunk battery disconnected.
Installed 550cc injectors.
Throttle Body shaft grind.
ECU and TCU tunes.
Double checked hoses and electrical connections as I reassembled.
Charged auxiliary battery once a month.
Reconnected battery. Good voltage.
Engine rolls over but will not start.
ESP Malfunction, Visit Workshop.
Turned steering wheel left/right.
Disconnected batteries for 15mins.
Still the same.
Any suggestions?

Did you install all of that stuff after storage and prior to starting for the new season? You pull codes? Pickup an ELM327 and a $6.00 Android Torque app. Every E55 owner should own one to pull,erase codes, and IATs,etc.

Yes, I tried Dyno Mode, Manual Mode, Sport Mode, Comfort Mode.
In Dyno Mode, alarms came up ESP diagnostics unavailable.
Moved the car back and forth a couple of feet.
Turned on/off towing alarm.
Still no go.
Star not an easy option for me. Car is in basement, will be very difficult to get it out of basement and nearest MB dealer is 80 miles away.
Would a OBDII handheld reader be of any use?

Something I forgot to mention.
Before attempting to start the car. Key was turned to #2 position to allow fuel pump to fill fuel rail. ESP Malfunction appeared at this time.

Call your local auto parts store and see if they can lend you an OBD2 scanner. Some do it and they use your credit card to secure it. Worth a shot just so you can see what codes its throwing.

crank position sensor allows the car to crank but not catch or start. Does it say ESP malfunction or ESP unavailable? If it says unavailable, its because the battery was disconnected and you need to resync the steering angle sensor by turning the steering wheel left and right lock to lock.

I have never seen ESP malfunction cause the car not to start. So it just crank and cranks and doesn't start? Change your CPS then give it another go.

Before you replace the CPS (yes it is a common failure but go back to the basics first) if the ESP light is on and the engine will not fire I'm thinking a fuse is out or some electrical plugs were not properly connected during your upgrades. Check all your fuses to rule out any shorts, then recheck every electrical plug you may have touched and all around them, then replace your CPS, if still no luck I would suspect your ecu needs to be sent back and reflashed.
Also from my experience, sometimes the pins inside of electrical plugs bend and will not contact the receiving end of the female plug, check that as well.
Best of luck!

maybe a shot in the dark but, check your TB. I think you can unplug it and plug it back in and it will reinitialize. Make sure it is fully closed. If the ECU sees accelerator and throttle at different positions, it will shutdown the TB and throw an ESP code. My 80mm ate a gasket. The gasket held the throttle slightly open while the accelerator position was 0 or closed. I got the ESP code.

I had disconnected Throttle Body plug and checked pins/connections and cleaned with electrical contact cleaner. Appears OK. I rechecked all Injector connections. I disconnected and reconnected ECU connections. I had checked all fuses in the ECU fuse box. I checked bypass valve and MAF sensor connections. I will re check TCU connections and purchase a CPS sensor. Strange that I never had a code/alarm/issue for two years and something failed during storage.

Disconnected battery again.
Turned ignition to #2 for 1 minute to allow ECU to read TB position.
While waiting, I received another message: Oil Level Sensor. visit workshop.
