2005 Jetta. 2.0 BEV Got a code of P2181. Anyone know exactly what the problem is? I know it's a "engine system coolant performance" code but need to be a little more precise. Coolant has been changed 2 yrs ago with no issues since then. Thanks.

 

VAG Error Code: 18613
EOBD II Error Code: P2181

Fault Location:
Performance Malfunction in Cooling System

Possible Cause:
-

Possible Solutions:
Check Engine Coolant Temperature Sender (G62).
Check Coolant Thermostat.
Check Engine Cooling System.
Put the key on, fan speed on 1, and push the a/c switch. Are both fans kicking on? If not, you found the problem.
Put the key on and fan speed on 1 with temperature set to hot. Does heat come out readily from the vents?
No. Probably the water pump is gone.
Yes. Probably the thermostat is gone.

Special Notes:
Check the stored Freeze Frame data with this fault code. Freeze Frame information will be found in the fault code description (if the module supports it) or in Generic OBD-II if the vehicle complies with those regulations.
Freeze Frame data stored at -40*C is generally an indication of a faulty ECT or wiring.
Freeze Frame data stored at +140*C is generally an indication of a faulty ECT or wiring.
Freeze Frame data stored with in the 68*C ~ 80*C range is an indication that the vehicle was close to, but not within, the cooling systems normal operation range. The Thermostat itself or Cooling system components may be at fault.
