I have an 2003 XK8 4.2 V8. The temperature gauge won’t work despite my having changed the temp sensor, I bought a new coolant bottle. The car doesn’t overheat. I’ve stopped driving the car because I’m worried I might damage the engine should it overheat. I tried using an bluetooth OBD2 to check the car temperature gauge… Using a mobile phone app Torque… But the message says no data…does that mean there’s no communication between ECU and the temp gauge?
Please help. I miss driving this cat
