Now I have other issues popping up. 2 weeks ago, air conditioning went out and now blows hot and last week, engine fan began cycling on and off every 10 seconds. Seems my water pump may be going out.

I have a Carly adapter to run a diagnostics and I have a couple of codes in need help dissecting:

- Fault: Air mass plausibility: air mass too high
- Code: 102001

-Fault: Engine Cooling: Coolant pump speed is outside the tolerance
- Code: 20A701

- Fault: Boost pressure control, plausibility: pressure too high
- Code: 120208

- Fault: Boost pressure control: shutdown due to reaction
- Code: 120408

- Fault: High-pressure fuel injection upon release: too low pressure
- Code: OBD 02 P11A401

- Fault: High-pressure fuel at or after the release of injection (second environmental condition set by time delay) to low pressure
- Code: OBD 02 P11B401

- Fault: :Interface DME / DDE: forced upshift requested by motor overtemperature or invalid signal (status switch warm-up drive 0x3FB)
- Code: 421722

- Fault: :PWM reduction due to excess temperature / PWM reduction due to overtemperature
- Code: 800334

- Fault: :Parking heater: not done Leitungsbefuellung / Stalemate irreversible module error
- Code: 8011FF

- Fault: :Compressor: shutdown due to low pressure in the refrigerant circuit
- Code: 801225

- Fault: :K-LIN 6 xAUC Sensor: Internal sensor error
- Code: C90D60

Where do I start?
