A207 - AdBlue fault diagnosis

An E class recovered in, in a no start condition. The calibration data for the car had become corrupted and the car thought the tank was emtpy when it was not. We re-calibrated the level sensor after confirming it was functioning, added some more fluid to ensure it went up by the added amount, and confirmed all faults. The customer saved approximately £250 by coming to us over the main dealer.
