It was common practice to idle early turbo engines for one to two minutes before switching off to help protect the bearings in the turbo. It was done to ensure the turbo was not spinning at high speed and was not too hot when the oil pressure and flow was shut off. As you say some people even fitted aftermarket "turbo timers" to delay shutdown for a period after the ignition was turned off. Early turbochargers weren’t as robust or reliable as today’s are and some manufacturers recommended a short idle before shutting the engine down, particularly immediately after operating the engine at high load. Turbochargers and turbocharged engines, such as the 2.0-litre diesel and 1.4-litre petrol engines in the Cruze, have come a long way since those early days, so you don’t have to let them idle for a period before turning them off.
