Hey,I have a 2007 cdti. Over the last couple of months the car has struggled to start every now and then. I have to keep turning it over longer than normal and it coughs and splutters. The EML comes on and when previously scanned it came up with crank sensor. It would always start after turning it over again though. I changed the crank sensor and it seemed ok but then 2 or 3 weeks later it did it again. The EML light stays on for a day and then goes out again. Any one had any similar issues?
