I have been having an intermittent problem with my ST TDCi (Mk3 - 05) in that we have been driving along for the past few weeks and the dials suddenly all drop to zero, swish around to max and then resume their normal position. In addition, the fuel range drops like a stone and the ESP light activates itself.
There is no loss of power and the next time the ignition is switched on, the ESP light switches itself off.
I have noticed once or twice that the battery light flickers for 1/2 seconds about 1 minute before the dials have their dance.
Do I have a battery problem or is it an electronics problem?
