1.2 TSI engine warm up time

Best to idle without moving initially whilst cold - but then vary the engine revs once it begins to warm up until normal running temp is achieved. Stationary this takes at least 30 mins of engine running in the case of a 1.2TSi, equivalent to a 10 mile journey or more, thoroughly warmed through and any exhaust condensation gone. Better still let the car tickover for a while when stone cold before driving off on a journey of 10 miles plus (mechanical sympathy) . Worst of all are drivers who start their cars from stone cold, drive off immediately on a very short journey of a mile or two. Buying a very low mileage car can be a good deal if it has been used little but covered decent mileages on each use or a very bad deal if said vehicle has done loads of very short journeys. DPF anyone?

Really??

And which "proffesional" body gave you this advice?
