With the latest diagnostic equipment such as Bosch KTS, Delphi diamond 2 and Denso DST we are able to access most vehicles management systems to check faults and carry out actual value tests on the systems sensors and components allowing much more accurate diagnostics.
The ability to plug directly into fuel pumps fitted with their own ECU’s (as fitted to Vaux Vectra, Astra, Ford Focus, Transit & Volvo FL6 to name but a few) is now possible, again leading to more accurate diagnostics.
