Hi All.
Thought i'd share this success story in case anyone else has a similar issue.
I have a MK1 412d sprinter. Last 3 years or so its been suffering intermittent power loss during acceleration or under load.
Classic turbo boost pressure loss or fuel starvation issues i hear you say. Not so. None of the other usual internet search suspects either.
It was a faulty MAP sensor. No fault codes registering. The issue got steadily worse over the 3 years (more frequent) until it was unbearable. I'm guessing the MAP sensor was just throwing out false voltage readings and fooling the ecu into thinking the pressure in the manifold was different to what it actually was and then telling the IP to fuel for an incorrect pressure.
New sensor and the vans driving better than ever
It took so long by the way to find the issue as it was initially very intermittent and i just put up with it and also there was an issue with my IP housing that was creating other issues.
