    where would i find said Power Supply Terminal 30? any ideas on how to fix this?

    would rather like to get this sorted.. got two days off tomorrow and friday so im going to be having the beast apart!

    may have something to do with why my xenons are flickering before coming on

    already got to do my MAF, Stat, Temp Sensor, full oil change and have my passenger seat out for airbag connections! may as well do this at the same time!!

    Have you disconnected the battery at some point?

    18010 /P 1602 / 005634 - Power Supply B +
    Terminal 30 : Voltage too Low

    Possible Causes
    Cables on the Battery were removed
    Battery weak ( voltage )
    Generator Disfunction

    Possible Solutions
    Check Battery Cables
    Check/ Replace Battery
    Check/ Replace Generator

    Special Notes
    If multiple Control Module have Power Supply
    Faults stored, it 's most likely to be one common
    Problem like the ones shown above. Otherwise
    when only one or two Control Modules have
    such Codes stored you better start searching at
    the individual Power Supply of these Modules .

    Has your radio ever reset itsself. This fault appeared when my battery was on its way out, not fully dead but crank speed was slower than normal. New battery and bobs your uncle.

    see its really odd like i put a volt meter on it today and it read 12v stood still and when the engine was running 14v and yet i was still having problems with flickering HIDs!!! they would flick on and then die and throw a bulb out error on the dash..again after a few clicks on and off they work fine?!

    Unfortunately using a volt meter will not tell you of a dying battery. Mine read 12.3 stationary and 14 running but was still buggered, you need a load tester to properly test the condition of a battery. Try find someone with a good strong battery (60 Ah or so) and try using it on yours (or jumping even, due to loosing radio codes and the likes) and see of the crank speed is noticably different.

    The flickering headlights are more than likely due to bulbs on the way out or dodgy balasts. Are they a bit pink or purple coloured
