Had an cam belt engine blow-arhhh! bill was £1800...all parts changed,etc. EML came on shortly after driving the car and car was really flat(about a week) problem stated Particle filter 1901? Had new bulk head sensor fitted, still EML kept coming on. The whole system was blown through and cleaned....still light kept coming on. New Pirticle Filter fitted £800(engine re-callabrated), Still ran flat but this time the particle filter issue on the EML became a turbo sensor issue, had that replaced and reclalabrated,still running flat! Help Car is a Vauxhall Signum 1.9 Elite..
