Hi All,

Sorry if this has been asked before but,

Had an error code of P0406 with the glow plug light flashing.

Assumed the EGR valve had clogged up so took it off and cleaned it and then replaced.

Drove for about an hour without a fault then the fault appeared again the following day.

So my question is has anyone had the small motor in the valve fail because that's the only thing I can see that could be wrong and can this be checked with a multimeter etc?

Any help is great!!!

Cheers
