16500 Enigne coolant temp. sensor (G62): Implausable signal
P0116- 35-10 - - - Intermittent

Bad info from the coolant temperature sensor can throw your mixture off.

Check the value from the ECT, both with the engine hot, and after it's been sitting overnight. Hot it should read 90-110C. After sitting overnight, it should be within a few degrees of ambient. Meas. Blocks, Group 001, Field 2.

Since the code is "Implausible signal, intermittent", I'd have a look at the wiring and connectors. But VW has installed a huge batch of crappy sensors some years ago and updated replacments are pretty cheap.

I had the error so replaced the sensor. The old one is black in colour and notorious for failing according to my dealer. Replaced with the revised green coloured sensor and it's been fine.

 

[Redcupra20vt]

did you replace it or the dealer?

eithre way, how much did it cost ya?

If its the one I am thinking of they are about £20ish. 2 minutes to fit. COOLANT COLD.

yeah myself but be warned like h100vw said, make sure the engine is cold as u loose quite a lot of coolant when u change it and u dont want it hot!
