156 2.4 jtd

UDC Failure

I have a 156 2.4 jtd multivalve which has recently started to give the message "UDC Failure, Go To Dealer". This does not always happen and normally switching the ignition off and on a few times corrects it. The glow plug light does not illuminate when this message is shown so i presume it has something to do with that. Once the fault clears itself the car starts straight away. Other than that the car is fine.
Can anyone suggest something that i can check or is a dealer visit necessary.
