Cheers. As I said, you can't guarantee that it was the fuel. Okay, let's put it this way. If you read my post here, you will see that I had accumulated ABS/VSC errors. If I simply emptied my fuel and refilled it then proceeded to reset my ECU, you would jump to the same conclusion that it was the fuel wouldn't you? But as I said in my post, it was random ABS/VSC errors that after resetting them, did not return.
