Hello, my 330d suffers a problem with an orange DDE light coming on when is given some beans.
The DDE light is like a diesel glow plug symbol with DDE written underneath.
However, it doesn't seem to do it when the engine is not up to normal operating temperature.
When this happens, it goes into a kind of limp mode, but nothing too drastic.
If I switch it off and restart, the light goes away, however, sometimes the light will stay light after restarting but then doesn't appear to then be in limp mode.... Wtf.
I have replace the fuel filter and had the fault code scanned which comes back as low rail fuel pressure.
I have had no starting problems whatsoever or rough running at all.
Any ideas??
