Hi folks, I have a 2007 Vito 111 CDI For some time now, my EML has been on, and my Vito has been down on power. A few weeks ago, I found a blown fuse in the main fuse box, and when I replaced it and took the car out - full power had returned and the EML went out. This was short lived, as a week later the light re-appeared and I lost power again. when I checked the fuse I had replaced earlier, it was fine. I took the car to Mercedes, who put it on the computer and told me to change the EGR valve and the Air Flow Meter. I changed both of these, but the light is still on and I'm down on power. Interestingly, I still get full revs, just not full power. The computer report from Mercedes also said there was a funny reading from the Lambda sensor, could this be a possible cause? The car has been de-catted as a previous turbo failure blocked the original cats, so I wondered if that would be the cause of the funny Lambda reading. I've spent a load of money on this already and I'm reluctant to keep throwing money at the problem. Any suggestions greatfully received, Brian.
