Electrical gremlins strike again!!!!
 

Hello guys and gals



Im sorry its taken so long to get on the forums! ive been stalking the site for a little while now and has helped massively with problems on my 2004 MG ZT-T 190+ in monogram nocturne blue.



but think my new problem is not going to be something i cant do myself :duh:


so from what ive researched i believe it to be a k bus issue but if anyone else has any suggestions please fire away:D


Problem

- Indicator stays on for a few extra seconds longer on the dash.
- other times indicators work fine outside but nothing happens on the dash

- high beam light comes on dash even though highbeam isnt on.
- headlight warning lights come on when door opens even though all lights are off

- central locking telling me a door is open when everything is closed.


- recently wipers have not worked until a few minutes after the car has been running, heater showing errors or screen,





all of these issues are intermittant and can be perfectly fine one minute and a nightmare the next.


things ive already tried.
- inspected lsm, bcu both fine

- checked every fuse for condition and continuity

- both plenums bone dry
- disconnected tv modules in wheel well.
- done many hard resets on battery



have had a look at the t4 map and looks like cb750chris is not far from me at all what is the best way to contact him?



thank you for any help in advance

Suggestion :

Try disconnecting the white 12 way connector, hidden on the underside of the engine fusebox. Clean the contact for the thin yellow with blue wire. This provides power for the k bus, and has been known to make intermittent contact.

Chris is highly recommended.

Thank you for the suggestion :} Chris has given me a few extra things to look at but will try that first as will be easier to get to :D



Ah that's good to know!

Thanks when I first made the account I didn't have the option to pm him hense I was getting lost :duh: But panic over I've now pm'd him and currently trying to get to the bottom of it :)
