Tin top (Octavia) - wierd elec fault - help!
Hi all,
Hope somebody can give me an idea of where to go looking....
I have had my Octavia tdi 90 for 6 years now, relay 109 was replaced in the first year I had it.
Yesterday I had a new wierd fault:
Driving along, wife noticed that trip window in cluster had gone blank, then came back.
Switched off engine at end of journey - and cluster was wasn't showing, then slowly came back to life (this inidicates low battery normally - ie
alternator has stopped charging).
Tried to start car but cluster totally died as the coils came on (again me thinks low battery)
Cluster came back up after a minute or so
Faffed around a bit - then went to lock the car, it locked and central locking worked (usually dies pretty early with low battery).
Thought thats odd, so re-opened car (central locking working again)
Put key in and succesfully started car....
So, I appear to have the worlds first intermittent flat battery 
I will check all battery connections this morning but after that I'm baffled - any other ideas?.
Greg

Not unknown for cars with the CAN Bus system get weird electrical glitches that clear themselves after a restart.

I would also check the battery earth to body connection.
Check for damp carpets. ( had a real fairy light episode with my passat 90 treaced to car loom to dash connectors that had got damp due to the bunged
up drain holes )

Check the manual to see if there is a reset procedure. Normally, this is turning the ignition on and off a number of times.

My 04 passat used to do that - it seemed to sort itself out.

Had a mini years ago do the same sort of thing. Completely cut out then go again.
Fault was a loose battery terminal.
Scot's do it better in Kilts.
