After Long life service - the service interval display after I got home was reading 9,300miles. I presumed they'd put the wrong service figure in so called them up and went back yesterday. They adjusted it no problems, back to 20k (which I saw/noticed myself this time) after getting home (4miles) I checked it and it was back down to 9,300miles! Does any one know what could be causing this? to loose 10,700miles for a 4 miles journey is crazy. Thanks in advance.
