This little nemo 1.3 hdi came in for harsh running issues,blue smoke and cooling fan on permanently. No fault codes were stored and no warning lights on dash so after chatting to customer about his driving journies found the car was stuck in regen and the short trips would not let it complete. We carried out an extended road test monitoring live data until regen was complete. The car is now smooth running/ no smoke and fan stopped. No parts required and customer educated on how to use his car. Another happy customer.
