Hello all, and thank you in advance for your thoughts. To my understanding, turbo lifetime is improved by a post-use cool down period. This is substantiated by auto-start and security systems with a turbo cool-down timer feature. Have the AMG engineers devised some cooling system for the GLA 45 turbocharged 4-cylinder that continues to provide coolant after the engine is shut off? The fact that the default (at least in the US) is for the engine to cut-off when at a full stop with the brake applied, makes me ‘hope’ they have engineered a solution for the turbo cool down.
