I have just purchased as 2004 2.8 Ford engine V6. The Engine Management Light is constantly on so, firstly, I checked all fuses and they are fine. After I checked them, I started it and the EML went off. I drove 10 mins up the road, switched the engine off and re-started only to find the EML back on! Any ideas on what the problem maybe or how to resolve this? Is it right that a 'Vag-Com' diagnostic check cannot find all the Ford faults? If so, can anyone suggest the best diagnostic check? The car runs and drives like a dream, but this light is worrying and I need to get it sorted. All help appreciated! Cheers...
