Hi Guys

Can anyone tell me if they have successfully communicated with the Engine managment system on this vehicle using a Bosch KTS. I know I have managed with the car range using this engine, but am unable too with the vito?!

Its symptons are no boost and came to me with the main intake pipe off of the turbo.
I have managed to get a fault code (P2623) via EOBD and this relates to a HFM fault.

My problem is that even with a known good HFM fitted and everything else (intake pipe) resecured. I cannot clear this fault code even with just the ignition on. Live data is very limited in EOBD and I dont trust the autodiagnos scanner as most of the data is ???

Could it be a star only requirement?

Any info much appreciated

Ben
