Its caused by missing engine limits from the EEC.
A red bar on the oil temperature vertical scale/bar indicates that the recording in the DEU non-volatile memory of the downloaded engine limits data are missing or have been erased.
Fixed on the ground by putting the start switch to CONT for 10 seconds. The EEC will re download their info to the DEUs then.
I have seen it only once in 6 years on the NG
