Long story short my wife was driving the car yesterday and it threw up the MIL and IPS fault lights. She said it shifted rough for a second then acted fine. I pulled the following info off of the car using Torque on my Android phone:
Vehicle Manufacturer: Lotus
Vehicle Calibration ID: Not present
Current Fault Log
------------------
P0700: Transmission Control System (MIL Request)
RXE: Unknown code - More information may be available on the web
ROR: Unknown code - More information may be available on the web
P0751: Shift Solenoid "A" Performance or Stuck Off
P1613: [Chrysler] Loss of DIM Serial Data
[Dodge] Loss of DIM Serial Data
[Jeep] Loss of DIM Serial Data
[Seat/Audi/Volkswagen] MIL Call-up Circ Open/Short to B+
[Volvo] Throttle unit communication. Signal too high or signal missing.
Pending Fault Log
------------------
ECU reports no pending faults
Historic Fault Log
------------------
ECU reports no historic faults
Other discovered fault codes
(possibly pending, current or manufacturer specific)
----------------------------------------------------
C1116: Unknown code - More information may be available on the web
P13<R: Unknown code - More information may be available on the web
ERR: Unknown code - More information may be available on the web
Freeze frame data showed nothing. I cleared the codes and started it back up for a drive. Lights immediately came back on and car was stuck in third. Additionally the stability control light was on this time as well. Sport mode would not engage also. Tried numerous restarts with the same behavior. Pulled codes again and same codes. Freeze frame this time showed this:
Vehicle Manufacturer: Lotus
Vehicle Calibration ID: C13����
����
Freeze frame information:
------------------
Engine Coolant Temperature = 71 °C
Fuel Trim Bank 1 Short Term = -0.781 %
Fuel Trim Bank 1 Long Term = 0 %
Fuel Trim Bank 2 Short Term = -0.781 %
Fuel Trim Bank 2 Long Term = 0 %
Engine RPM = 715 rpm
Speed (OBD) = 0 km/h
Timing Advance = 7.5 °
Intake Air Temperature = 48 °C
Mass Air Flow Rate = 6.46 g/s
Run time since engine start = 16 s
I then went inside in despair and searched the forum. Went out and jiggled/unplugged and replugged the throttle body connector. It didn't seem to be loose. Cleared codes again and started it up and it ran like nothing had ever happened. Ran up and down the gears several times in sport mode and all was peachy.
I am guessing this was likely caused by one of three things: 1. Radium Intake 2. Throttle Body Connector 3. Old ECU/TCU firmware. I suspect the culprit is number 3. I bought the car in January and the dealer allegedly updated the ECU and TCU to the most recent version immediately prior to my purchase but based upon the dealer's conduct in other areas I have my doubts. I am 4 hours from St. Louis and 5.5 hours from Atlanta which are my two closest dealers so it is no trivial matter for me to pop in to update the ECU and TCU.
Any input?
I still love the car but was a bit delusional to believe it to be a DD, especially in IPS guise. I am literally counting down the days until my MKVII Golf gets here so that the Lotus can sit in time out in the garage when it acts naughty and won't cramp our style to such a large degree.
