I learnt my lesson the easy.
Bought 330i M54 in Durban. Drove it down to Cape Town. Looked at the expansion tank when I got here and found it was the original from 2001 :hammerhead:
Then I found the thermostat was stuck open :hammerhead:
Replaced the expansion tank, thermostat and waterpump a week later after buying the car.
Luckily car was fine, but it could have gone so wrong.
