Help No Coolant Reading Showing On Hidden Menu, Cooling Fan On!
Hi everyone urgent help needed!!!!
Just purchased a mini cooper 1.6d 59 reg, with 99k miles. I noticed right of the hat the cooling fan is constantly on even from cold, however it goes off after 5 minutes from shut down. I checked the hidden data option 7 and the coolant reading is showing ttt0c with no reading from cold and even when warmed up no reading. I do get hot air and a/c is never used.
There is also a hissing noise from brake pedal when depressed.
Can this be related to the whole coolant housing the mechanical thermostat stuck with the combination of a after market temp sensor? Is there another sensor that detects the coolant temp that triggers the fan? I ask because there is NO readings of the coolant temp at all under the hidden menu.
The hissing noise from brake pedal can someone tel me what part i would need?
So far i changed the coolant sensor after market the green bit but nothing changed. Please advise needed.
