Hi, I've just joined on behalf of a damsel in distress, she has an R reg disco that is developing lots of niggly faults. The main one causing problems is that she has no speedometer or gauges working. Where should I begin to look for the problem? Also because the fuel guage is not working she has to brim the tank full of diesel which then leads to a leak somewhere at the rear of the vehicle, leaving puddles of fuel everywhere. Not even had chance to look at the vehicle yet but any pointers would go down well!!!
