I had simalar problem on a customers car. Turned out to be the inlet flap motor on the front of the engine. It lost its position sensing and the engine ecu would not go to sleep causing battery drain. The inlet flap motor was making a noise all the time trying to find the position it wanted. Have a listen for any strange noises under the bonnet with it switched off. |

The engine ECU give up after 5 cycles of failed flap repositioning and stores an error.

Total drain should be 0.023 ma when car has (gone to sleep) shutdown it takes 30min to shutdown ,when removing each fuse this waiting time will be needed to get a true indication that the circuit is not the cause.the CAN bus will wake every time a fuse is removed .

Tony the car was delivered to the dealer last night and a courtesy Freelander delivered but due to my expired driving ban I cannot drive it Interesting about the 30 sec delay I would have thought that the LR technician should have known about this when I suggested it to him. The twin electrics were all fitted by the main dealer so even any probs there are not my problem Simon 2007 Freelander 2 Rimini Red HSE Auto (Daily Driver) 1991 Range Rover CSK No. 98 (Toy) |

Simon,delay required on removing each fuse in turn is 30 mins, fl2 shares many things as its built from the Ford parts bin with the same PSA engines as our mondeo and smax (dw12),I cannot give you any more help than this as Landrover software is different but shares the same IDS platform,I have done this test many times and have found bugs in audio/Nokia comunications modules software from bluetooth pairings (Blackberry storm) keeping the unit awake and drawing current. Hard reset and the car will be ok on a temp basis,but ford have us download from a flash drive straight to the comms module but this is car specific,and may not be your problem,please let us know how you get on at the dealers,this will help build known fixes to probs on this forum.

Had a flat battery after a few days without using the car. Started with no problems via another battery, call out mechanic said it was a very common fault with modern cars due the systems being on stand by if the car is left unlocked as mine was. The answer, confirmed by Land Rover, is to always lock the car with the remote; this then shuts down virtually all systems. If the car is left locked for an extended period, say 3 weeks or more, the car goes into complete shutdown and can only be opened with the metal emergency key. Putting the main key into the ignition slot will then bring it all back to life. Have had no further problems since I started the routine of locking it. Hope this helps. |

Had a flat battery a few months ago, AA man checked everything, jump started it and tested battery and it was charging fine, gave it a while and restarted and no problems. AA man could not find a cause.
