Hello, I see you have a issue with the exhaust fluid light coming on. These lights can at times be difficult to turn off, first off you need to have the dtc codes scanned to see if there is an issue and then the exhaust will have to be put into regeneration mode either with a scan tool or by driving. With that said, what was the original issue with the light on when you had a dealer service it? Was the fluid run to low, or did they fix another issue and not get the light out? Sometimes after service the light may stay on and can be difficult to turn off, I know a few things you can try, just need a little more info and a scan tool will be a great help if you have one.
