Coolant Temp Sensor CEL
VAG reads the CEL as this:
1 Fault Found:
16502 - Engine Coolant Temp. Sensor (G62): Signal too High
P0118 - 35-00 - -
Readiness: 0000 0000
So I changed the coolant temp sensor under the flex intake pipe. The original one was green and the new one was green as well. Still got a CEL and same fault code. Any ideas? Maybe the new temp sensor is bad as well?
thanks

Maybe wrong one, how about the one in the lower hose. What does your temp gauge say?
Audi has had shi*&%ads of problems with temp sensors, I have had a couple be bad right off the shelf. Can't remember if the latest one is green or blue. It's been updated so many times.

Re: Coolant Temp Sensor CEL
Was there any pink coolant in the connector of the old sensor ? They can leak into the connector and then push the coolant up the wire into the ecu . It's hard to believe but I have seen this 5 or 6 times .

Re: no coolant in the connector...
Do you have VAG? What temp is the gauge indicating . if you have a VAG then go into the measureing blocks and look for the coolant temp . should be in the first few channels . The car should be running at around 88*C . I would watch this value as the car comes to operating temp. It is possible the car is running too hot and setting this code .
The switch in the lower hose is for the cooling fan .

Temp seems to be a little erratic. Tick and a half in about 1 min u pand down. Thermostat or sensor?
