Hi all, I have 2006 sri 150 diesel, which recently broke down, spanner light on, and would not start full stop. Recovery man read codes stored and only on there was p2279 which he said was air intake system leak which he could not fix at road side, after looking at some forums for advice I cleaned the egr valve, boost pressure sensor, and checked all the vac and boost pipes all seem ok. I then removed the DPF filter and again following advice cleaned out all the soot and refitted. The car now starts up but there appears to be no boost, as there is a lack of power, there is also a kind of whistling/ humming sound coming from around the turbo unit which is audible from inside the car so is quite loud. If driven on the motorway spanner light comes on and the fault stored says p1901-75 Particulate sensor high differential pressure. Any advice on sorting this would be appreciated guys,
Ps the car had no problems with boost, before I cleaned the dpf have I done something wrong maybe ???
