j_jza80 Posted October 21, 2009 Share Posted October 21, 2009 Hey guys, my girlfriend has a 1997 Seat Ibiza 1.9 SDI diesel (Non turbo) and she's noticed the fuel economy has taken a sudden turn for the worse, although apparently it feels a little nippier. I was wondering if it could be an 02 sensor fault? there's no visible fuel leaks and it hardly smokes at all (Very odd I find for a diesel with 130k on the clock). I've checked the water and oil to make sure there's no contamination, and it looks spot on. I don't think she's had it serviced for quite some time, so i'm going to try that, but any input would be greatly appreciated. Thanks in advance, J Quote Link to comment Share on other sites More sharing options...
