    The reason i ask witch relays stay active and the mechanics cant find the cause is that the the power down of the system goes in steps. First it goes from 3 amp to 1.5 amps, then it drops to 0.7 amps and finally it drops to 0.03 amps. Its the last step from 0.7 amps to 0.03 amp you cant test by removing fuses or modules. In that case you need to monitor the SCP network to see witch module keeps sending a message witch prevents the system to go to sleep.

    You need a diagnostic tool that can monitor the SCP network after the ignition is turned off and this can only be monitored with IDS.

    Good morning all Iím finally picking my car up later today . Itís been nearly 3 months so looking forward to driving it once again .its not quite fixed ! They have fitted a switch so I donít physically have to remove the earth lead from the battery . Iíve asked for a detailed invoice so I can show you guys later how far they got with the battery drain problem so hopefully you knowledgeable guys can maybe spread some light on it . Was told on the phone yesterday they know whatís causing the drain but canít find a way to stop it . Theyíve fixed the aircon and fitted a new horn and the bill is about £600 which to be fair Iím quite happy with as they have spent hours upon hours trying to fix it and only charged me a few hours . Considering the local garage charged me £500 for a part I didnít need Iím quite happy JCAT have only charged me a few hours . Anyways Iím waffling a bit . Will post details later today

    This is whatís written on the invoice ;check quiescent drain current - measured after shut down with car in locked state at 700mA.goes on to say current drain discovered to be related to rear general electronics module - when disconnected drain within spec at 70mA. Tried substituting in another rear gems module but drain again at 700mA . Drain must be due to a Cct driven by rear gems module . Discuss with customer labour time already charged and unknown time required to try to identify the cause . Fitted battery isolator to prevent drain

    What year and model do you have?

    Which relays stayed powered upup?

    Now that we know which module was not shouting down we can look at the wiring diagram to see if we can get anywhere with it.

    I gather it's an STR.

    Voltage drop across each fuse is likely to be a fairly easy way to see what's staying on once the 40 mins or so shut down time has elapsed but first it would help to know whether that 700mA is after that period.

    It did state on the invoice that the 700mA was After the 40 mins shutdown period 04STR

    It could be as simple as the boot courtesy light not turning off when the boot is closed, if it's driven by the rear electronic module.

    Looking at fig 3.06. The only relay that is controlled directly by the the rear module is the fuel pump

    Will print it out tomorrow to have a better look.
