Following on from this thread:
and a few other threads that unfortunately seem to die off without resolution (so at least I know I'm definitely not the only one finding this)
I would like to at least clean the Throttle Body before taking car to dealer.
The symptoms I'm getting are exactly like what others have described when the Idle Control Valve breather hole gets blocked in petrol engines but given that I'm driving a Diesel engine, there isn't one to go wrong.
There doesn't seem to be any pattern to it wrt to driving style (agressive/crusing), engine temperature, fuel type (supermarket vs. Shell or BP etc), idling while stationary or driving along as normal.
...and it's not the rubber joints on the turbo vacuum pipes kicking me into limp home mode. Already had that problem previously and thankfully sorted that quickly and without costing a fortune. It went into limp home mode in that case, this is very different, you're lucky to limp to side of road.
Occasionally if you switch engine off and back on again it comes back immediately but more regularly now it takes maybe a dozen goes at it over maybe 2 or 3 minutes. And then sometimes after that it can run perfectly for the rest of the day.
It's like it has dirt or water in the diesel but have already had this checked and apparently that's ok and fuel filter only had a small amount of condensation that I was told, "wouldn't be anywhere near enough to give you what you're experiencing anyway". Airflow sensor checked and reported to be fine and no cat problems.
Also tried a dose of redex but didn't make any difference.
Anyone any suggestions as it's becoming dangerous now when it dies while driving along and I can't get it cleared within 2 or 3 restarts while coasting.
Really frustrating part... NO ENGINE MANAGEMENT LIGHT!!! At least if I got that sodding spanner light, I would feel justified in taking it along to try to get codes read, but at minimum if someone could point me in the direction of how 2 clean the throttle body it would be much appreciated.
