Before the Terraclean Engine service the customer commented the car is running fine, but on occasion, it would sometimes produce a small amount of white smoke when the engine had warmed up.
First we checked the oil and coolant levels and also scanned the engine management for fault codes, but revealed nothing.
During the Terraclean service we monitored the engine with live data with our diagnostics equipment, and observed an occasional random misfire on cylinder 2 which seemed relevant and can be caused by several things, after the service the misfire didn’t occur again, we advised it would be a good idea to renew the spark plugs and change the air filter
