e32 fault is overheating due to water or transmission
both are on the the line you have stage 1 and stage 2.
i have this problem with a couple of truck i look after if the themosat has gone it will over heat all the time make shore rad is clean and air filter is clean and the transmission box is clean.
if truck is use at high revs and been use in small areas the truck will get very hot and keeping foot on inch pedal make shore oil is clean after cleaning truck fault not there reset code fault
