Dealt with problem without fuss
Engine management light came on when driving car home on the M25. It was an EGR valve fault. This probably would not show unless they has road tested it on the Motorway, so I accept it is unexpected and bad luck. I should Automotive have test drove it on fast road as well.. Superbia fitted a new EGR valve (I can see its new) without any argument. Its a really good diesel Toyota Yaris Mk2 that does not show its 100k miles. Now 5 weeks and 1500 miles later with no problems and actual 65.5mpg! I did not pay a bargain-basement price but the car is is better than average condition.
