95' 750 il and lately i have noticed this clicking noise from the engine.

Hi Wayne!
I have a 95' 750 il and lately i have noticed this clicking noise from the engine. Turned out it is coming from the climate heater valves. Giving me constant sounds like on and off but it does not happens every time. Just sometimes. other thing is i found my fuel tank leaking... Do you have any suggestion on that one?
Few electrical issues as well, mostly my fuel level does not accurate . After fill up it shows around 60 liters,but goes down to 0 ,light comes up etc. Look empty. Next day it does show about 45 liters again. Annoying right? Any suggestions are appreciated. Thanks

Are you saying your fuel tank has an external leak? If one side of the tank is leaking, the fuel level will display incorrect until the siphon can fill that side back up. Repair the external leak and the problem should go away.

I have something similar on my 96 750iL only mine seems to be related to OS temp and engine temp that never changes. A battery pull reset and it captures current reading on reconnect. Fuel tank did similar but tank popped back to normal when I filled it up on its own. i am going to look into body K bus , it may be my cluster. Have you tried to unlock the cluster function and check tank levels there ? I would be curious to also know your inst voltage as mine says 6.8 but probing all pins ( breaking them out at connectors ) I get 13-14V. K
