2011 Range Rover 4.4TDI random beeping
 

hi everyone,

I am new to the forum.

Right here goes,
I have a RR 2011 vogue 4.4tdi . . . . . When the temperature outside reaches anything over 22°c i get a high pitched beeb from inside the cab . . . . There are 12 beebs in total at every 55 seconds intervals?! This continues until the temperature outside the vehicle cools.
this beep continues when the car is parked and switched off, locked up . . . .regardless. . . .every 55 seconds :dunno:
I also get a high pitched beep that last around 15 seconds every once in a while when the car is being driven (not always when warm outside) I have spoken to a few specialists and they have no clue???

This has been happening for around 1 month now and the pattern is with the temperature outside.

The ecu housing fan is working not sure if its kicking in when needed tho, I applied power to this fan and it appeared to work fine with a separate power source . . . . I've also applied a ice pack to the the ecu in the high temperature to cool the ecu and still the beeps continue.

Any ideas would be gratefugratefully received
