[QUOTE="PaulR, post: 887046, member: 176256"] In order to give the best particulate emission result, it's important to warm a diesel engine up properly. Advantage can also be taken on this run to do an "Italian" tune-up (rev hard in low gears) to clear any of the particulates that have settled in the exhaust system. There's also the possibility that the vehicle might have winter diesel in it, Winter diesel has anti-waxing agents added whilst summer diesel has anti-foaming agaents added. Winter dieseel already in the car probably won't give any trouble but the other way round could concievably be problematic in extremis. No desperation in warming the car up if a busy garage doesn't have the time to do it properly. Leaving it idling is definitely not the best way. [/QUOTE]
