I fill up at my tesco garage every 2 weeks. Last time I filled up was on Sunday. I have since driving 200-300 miles since then. Anyway last night I drove for about 20 seconds turned round the corner and my car went dead. I thought maybe I never had enough power to keep it going in 3rd. Anyway I tryed to start the car and it wont start. Error message coming up saying engine fault contact workshop. And the orange rope on the dash is flashing yellow. Got the car into SEAT today. They 1st came to say it was a dodgy wire. After a bit they came out with some diesel in a glass and are stating its been contaminated. I know that I have not put any petrol in there. They aint quite saying its petrol but it has been contaminated. Then they bought out another glass of someone elses diesel. The other one did smell stronger and was a little bit clearer but nothing else. Anyway they are going to flush the diesel out my car and put new diesel in there. And if the car starts then they are going to put it down to this. They said it wont be covered by the warranty if this is the case. Feel like I been robbed if this is the case how can my diesel be contaminated. They said I would have to take it up with TESCO who I fill up with every 2 weeks. I just hope it does not come down to that and its something else. What do you guys think anyone had any problems with this error on the dash or with contaminated diesel?
