Car Occasionally Goes Completely 'dead'

[jayvee12]

Hi All,

I have a Mk 2 GS 430 Sport which I love dearly but the course of true love does not always run smoohly!

Occasionally ( maybe one time in fifty) the car will not start and appears to be completely dead or immobilised. Simply disconnecting the Battery for 10 seconds and re-connecting cures the problem but one day?????? I assume there is a hiccup in the immobiliser CPU but do not even know where it is, or want to touch it.

I always lock the car manually as my Landcruiser has had immobiliser problems when parked near the sensor for my automatic garage lights

Has anybody else experienced similiar problems or have any ideas please?

John.

As no one has replied, here is my 2 penny worth.

Remove both Battery cables and clean up, same for Battery terminals.

Go around car and clean all earth [grounds if you prefer] wire fixings.

Look in fuse boxes etc for corrosion or bad connections, same for key fobs.

Thanks Roy. Have already done Battery cables and terminals but have not done earth points. Will do!

I had similar problem at one time and found it was caused by my wireless front doorbell, it only happened when parking in certain areas near it.
