Cooling system : P2181
Hello, I have a 2006 audi a4 2.0t quattro. My check
engine light went on recently, then went off.
However, it had now came bsck. The code read for
cooling system. Main problem is in the mornings,
or hours after I haven't driven the vehicle it has a
tough time turning over. A mechanic said he thinks
I need to replace thermostat. I wasn't sure because
the car does not overheat. I thought maybe the fuel
filter? Sorry for tons of info. I don't know much
besides basic maintenance. Thank you!
2181 code can mean new thermostat, it can mean a bad coolant temp sensor or bad wiring or connection to the coolant temp sensor. It can also mean a low coolant level in your recovery tank. Not sure why the car has trouble turning over. what do you mean by that exactly, does it turn over slowly, does it turn over fine but not start, what?
It turns slowly, it starts just not in a normal manner. Sometimes have to give it gas to start
