Jaguar service be on that bullshit sometimes, you got to watch them. They quoted me $900 to fix my coolant low light that was caused by a broken wire next to the sensor. Told me it was from rodent damage and not a warranty item (I don't have any rodents in my area). I believe it was actually caused because the tie wrap was pulled to tight at the factory and eventually broken with all the vibration and heat.
Fortunately for me they showed me the wire on a video when determining the issue. Took my 15 minutes to fix myself.
The white wire was me testingu before fixing properly with a little solder (unnecessary for this) and some shrink wrap tubing.
