Hi. I have a Cruze diesel with about 6000 miles. I just checked my oil before my wife left on a short trip. About 10 miles into her trip the CEL came on. The oil was changed about 500 miles ago. The oil level was fine. Any ideas?
Nox/slow o2 is my guess but you won't know without a scan. Mine came on at 6k too a month ago just after an oil change at the dealer , needless to say it is still on at 7500. It has been 3 weeks since it's been at the dealer and they just say still on backorder(NOX sensor). I have talked to the GM customer service reps on here they just say to be patient. Some people have been getting good and quick service and others have not. I am just curious how patient do you have to be to get your car fixed?
