Dashboard electrics cutting out, but turn on over bumps?!? Help!

[henry]

Hi,

Apologies for posting straight away

Just getting her ready for MOT - changing discs and pads.. Already changed filters, oil and battery...

Suddenly this morning - dashboard, radio and windows started flickering during driving!! As if the key had been turned on and off - speedos now stuck and stereo and display are off

However - very strange!! - When engine revved or sometimes over a bump or brakes are pumped hard all of the above springs back into life...

Im hoping this is a known issue - maybe a dodgy connector?!? or a connector coming undone..

Anybody have any experience of this?

(By the way, all engine bay electrics still functioning - she starts drives and the lights work etc.. And fuses seem fine)

I'm hoping just a loose connector behind the steering column or maybe something like a connector loose in the engine bay - proximity to the engine vibrating or the like.

Please help!! and Hello!

cheers

Henry

It sound like a dodgy connection or a chafed wire.From a distance I can only suggest you check everything in sight,earths as well.Good luck.:thumbsup:

Right,

Checked all fuses I can see without buying a haynes manual..

Took her down to the stealership for a quote.... and they said get a new BSI that will be £500 pounds!!

Will try and send for re-programming - anybody have a link to BSI location and removal? I have done a search but nothing obvious on how to get at it!!

Many thanks

Personally (and I claim no great expertise here) it doesn't sound to me like your BSI needs reprogramming. Have you tried the BSI reset first? I would still go down the dodgy cable/connector route. I think you're going to have to dig further than the fuses I'm afraid.

Hi and thanks for reply!

The problem is, that I can't do a BSI reset as the drivers window is fully up - and the window switches along with the dash, display and radio do not function... So I cant put the window down!! Other items listed as being on the steering column fuse box are functioning though..

Don't think the dealers really checked properly tbh..

Should I just buy a haynes manual and check every fuse?

The MOT runs out on the 10th

Other than the fuse box in the engine and under the steering wheel, where should I check?

cheers

Have you checked the connectors to the fuse board? Not the fuses or the fuse holders but the actual connectors on the edge or behind the fuseboard. Have a look up behind the steering wheel and see if anything is loose up there as well.

This is almost certainly nothing to do with a faulty BSI. The dealer probably knows that too.
If the display is intermittent on a bumpy road then as has been suggested, the cause is likely to be
a loose/corroded connector or earth There are quite a few earths to check and you need to remove each one
and refasten it preferably using new shake-proof washers. HTH
