Hi all, This is on a 2012 3.0TDi S-Line Avant. Had a couple of 'false alarms' recently with the car telling me it's short of coolant, when it obviously wasn't. The first time it simply went away when I restarted the engine, the second time it persisted but went away after I waggled the wires on the sensor unit. So it's maybe a loose or dirty connection there. I couldn't make out if the sensor has a plug/socket arrangement, or if it's hard-wired in. Does anyone happen to know? If it's a plug I couldn't see how to get it out.
