2007 polo club 9n 1.4 electronic problems

[aslloss]

Here problems I amd experiencing
The car is 2007 polo club 9n 1.4L auto

Air bag light stays on

Abs on-> electronics in centre console blink and turned off-> warning light and beeping sound, power steering light on-> interior lights including one on dash board start become dimmed and off completely with head light off

During driving, few seconds later all come back up and seems to be normal except airbag light

On stop, power off, won't start again (even not make any sound when I try to turn it on) and a bit later start again with airbag light on

There is other issue that I am not sure whether it's linked to the problem I mentioned. The issue is that sometimes engine is shaking so that I can feel it and hear the sound, which get worse with aircorn on. Also, fuel gauge is fluctuating,,,

This issue happened couple months ago but was okay driving besides airbag warning light. However now it seems to be more frequent.

Is this problems arisen from ecu issue? Or something else?

Cheers

I had one of these once do all sorts of crazy things, similar to what you're describing. I tracked it down to a loose earth point in the engine bay, on the left front strut tower.
