As per title, haven't posted for ages, some stuff going. In fact had a nervous breakdown and everything but thats a different story.
So for now I need your help for a zed (not head) related issue.
In the car last week and both the abs and brake warning light came on accompanied by a very erratic speedo, after some time fault disappeared. The brakes were fine, i tested them and no malfunctions. Today again lights came on and speedo crazy and after a few minutes went off. The only thing I have done recently was fit some grooved discs to it but that was about 4 weeks ago and there were no problems since then. I checked the reluctor rings while discs off and no Probs (the fronts were changed last year)
The fault first happened last Tuesday after that really cold snap. I've looked in the Haynes and know the ABS sensors inform the speedo but apart from checking abs ecu connections which I'm due to do tomorrow am not too sure where to go after this. Any help appreciated and its nice to be back again.
