Hi sorry about your bad luck,the same happened to me a few years ago with a female police officer,light on dash she asked if it was ok to drive half/mile home and like a Pratt I said ok.car siezed 100m along the road she came into the garage and told us to deliver it when we had repaired it,with no bill I said why no bill she said what would it look like to a judge female taking advice from a professional,we had to pay in full I now tell everyone not to drive with a fault or light on,that was also a audi.terry
