Following Parliamentary approval of redrafted legislation, computer discs detailing vehicle emission levels will be distributed to every MoT station.
Hugh Roberts, director of the Independent Garage Assoc-iation, blamed car manufacturers for the chaos. He said: 'A lot sent the wrong information - either wrong engine codes for vehicles without a 'cat' at all, wrong oil temperature data and wrong information as to what emission levels could be achieved. They also missed out model ranges and in some cases manufacturers didn't respond at all. It has been a real mess-up.'
