Hello I am having problems with my mates e60 530i n52 engine .At first it had a coolant leak at the bottom of the radiator so we replaced it.
We have now found that there is no heat from the near side centre vents. I have bled the cooling system at least 4 times and it is no better.
I have checked the heater control valve on the near side inner wing and it is ok. I have also jet washed the feed and return pipe to the heater matrix and it is still no better. I have swapped the heater control panal and heater exchanger sensor in the top of the heater box and still cannot obtain heat from the near side vents.
Any help or advice would be appreciated.
