flashing o/d light?

Recommended Posts

i took a drive over the hills the other night (quite spirited driving) about halfway through i notcied my overdrive light was flashing i proceeded to drive quietly home with the light still flashing... the next morning when i drove to work the light was no longer flashing and everything seemed fine.

any ideas what was the cause of this? is it a temperature warning perhaps? or warning of iminent disaster comming my way?

Possibly a code 42 error. These can happen once several conditions are met, two of which are:

1) coolant is up to temperature

2) travelling at over 45mph ish.


Get the error codes from the ECU using the paperclip trick.
