I have an 03 Passat with 1.8t engine I recently purchased. The indicator light went off and reads the error code P2181 which I've read might be the temp sensor, thermostat, or water pump.
Is it safe for me to drive 30 miles to work as long as I keep an eye on the temperature gauge? Can I trust the temperature gauge to tell me if it's overheating.
I'd rather take care of it after work rather than losing pay.
