Fuel Temp Sensor Issue & Problematic Water Temp Gauge?

[driveforward]

On my way home tonight I noted that my water temp gauge didn't reach the usual 90 degrees, instead, it barely budged from the 60 minimum.. only moving a few mm off it at one point. Given the outside temperature was 26 degrees and my drive home was 22 miles I was a little suspicious.

Upon getting home I have checked the water and performed a fault scan. Apart from the obligatory climate control positioning motor errors which I cleared, the engine has listed the below fault which will not clear no matter how hard I try!

Controller: 045 906 019 AT

Component: G000SG 1532

Coding: 10002

1 Faults Found:

17571 - Fuel Temp Sensor (G81): Open or Short to Plus

P1163 - 35-10 - - - Intermittent

Readiness: N/A

Now, I wouldn't have thought this would effect the water temp gauge, however, given I'm unable to clear it, I think it's a little less intermittent than the ECU is letting on. Output tests verified that my dials are all working correctly

Are these two instances connected, or just random coincidences?

Thanks,

Ian

Hi Ian
I suspect the two problems are not related.
When my temp gauge started to wander between 60 and 90C, VagCom did not detect any fault codes. After wasting money on a thermostat I changed the temp sender unit and that fixed the problem.

If you have not already checked, this is what RossTech say about the fuel temp sensor
