My car is running codes P0011 and P2181. Can you tell me what that is please. 2004 vw jetta gl


P0011 - Camshaft positioning sensor
P2181 - Engine cooling temperature sensor.
If you have a repair manual (chilton/haynes/etc) these should be fairly simple fixes.
Camshaft positioning sensor for my car was $35 and took about 15 minutes to change.

2carpros.com suggested the P2181 is also fairly easy to replace

The check engine light stays on and the dealer said I need a themmostate, however it doesn`t leak or run hot. Can this be right?


If the check engine light is On the owner would have performed a scan on his car which would have given him some error code and the code will indicate that thermostat is faulty. Is the code p2181? if it is i think the thermostat is faulty and needs to be replaced.

How do you translate what the hand held computer diagnoses to the issue. Hand held said cooling system P2181?


it helps to tell what engine you have, there are 8 engines used in that model., but its a coolant sensor issue. I would pay a shop thats familiar with VW to check it out and recommend repairs.

What does the diagnostic code P2181 mean on a Subaru Impreza WRX?


this is a coolant performance code. Usuallly sets this code if the connector was left unhooked to the coolant sensor or the thremostat is stuck open. By any chance do you have a gauge that seems to be on the cold side ??

Engine light wont turn off


P2181 is a overheating engine, the engine is probably dieseling because it is badly overheated, dieseling is when the engine keeps running after the key is turned off and makes a knocking type noise, this can be caused by a defective thermostat, low coolant level, blown head gasket and other thing as well. You need to get this looked at before you destroy the engine.

CEL is ON. OBD code P2181. I already replaced the ECT 3 mo ago due to OBD code P0118.


P2181 is a overheating engine.  
Can be:
Bad fan themoswitch, temp sensor themostat water pump impeller fan motor or fuse on battery
check to see if fans work by turning on Air Conditioner (fans should run with A/C on). Turn A/C off, warm engine, check to see if fans come on, if they do NOT it may be thermo switch on radiator on lower left side, has 3 wire plug, takes 1-1/8" wrench/socket to remove.  This thermo switch controls fans when temp reaches 195F, if fans do not come on at engine temp 190-195F try  replace switch VW part number: 1J0-959--481-A  You can verify if the switch is bad by shorting wire 1 and 2 (fans should come on when jumpered).

Trouble Code


Hi Kevin,
There probably isn't a single answer every time. I found this for you on my hard drive...

"18613/P2181/008577 - Performance Malfunction in Cooling System
Possible Solutions
* Check Engine Coolant Temperature Sender (G62)
* Check Coolant Thermostat
* Check Engine Cooling System
o 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.
o Put the key on and fan speed on 1. Does heat come out readily from the vents?
+ No. Probably the water pump is gone.
+ Yes. Probably the thermostat is gone."

Check the electrical connector on the G62 first - make sure it is clean. Try running the engine with the G62 disconnected - does this make a difference?

Let me know how you get on. Cheers, D.
