A few days ago I drove my car (2015yr VW Golf MK7 Estate) out of the garage & noticed that the outside temperature reading was high (+8C) when I know it was less than +4C. During the drive (1hr) the reading got steadily higher & when I got to my destination it was showing +20C as the outside temperature, when there was snow on the ground!!
So obviously something wrong with the sensor, but did not have time to look at it properly until I got back home later that day. So removed the grille (two TX star bolts) & unplugged & removed the sensor (G17) along with the sensor bracket, as the bracket comes off easier to allow you to remove the sensor as getting the sensor off the bracket is quite tricky, & best done outside the car.
So a stone had hit the end/tip of the sensor splitting the outer plastic & revealing the inner white thermal paste & the bead itself. OK so order new sensor from dealers (couple of days to arrive as not a "line" stock item).
Here's the interesting part:-
Decided to remove the sensor & plastic bag the connector, as I thought its better to have no data than incorrect data being used. Now I knew it would throw fault codes for the 09 Central Electronics & the TPMS (03 ABS) modules...
Start car, warning message on dash re TPMS system error, ok that's fine...
Loud beep & parking sensors button blinking orange at me, ok that's strange...
Notice that the engine fans are at max speed due to noise, ..ok that's very strange...
Reverse car down driveway & fans are still at max speed & I know that the outside temp is +2C & the car is cold. So drive back into garage & fans still at max speed, lift bonnet,....yep both fans max speed. Switch of ignition, I ain't driving car like this!...
Refit the G17 Ambient temperature sensor, & everything behaves all ok, no flashing lights, no error messages & no engine fans at max speed.
So when the new sensor arrives I fit it & do an auto scan &........look at the all the fault codes!!! Now I had run a scan only a few weeks ago, so I know car was fine & ALL those faults have the same time stamps, so same creation date.
What gets me is how many modules rely on information via the data bus from that sensor!!! Some you expect, others are like WTF??
Anyway moral of the story, if your G17 Ambient (outside) Temperature Sensor is faulty or playing up, DO NOT unplug it, just order & fit a new one ASAP!!!
