Problems galore in new audi A4

Being an ardent Audi lover, I chose to upgrade myself to the new Audi A4 after owning an Audi a4 for 3 years (previous generation). However my joy was only short-lived as I started experiencing rattling noise emanating from the engine even after the ignition is switched off. Several attempts to reach out to the service team in my hometown were met with evasive, often shameless explanations like this is a new technology Audi have designed to let the coolant fan run to keep the engine cool even after the engine is switched off. The problem persists even today after multiple attempts by the local service team to fix the defect. I sincerely don't think it's worth a car your money can buy when there are some wonderful options to choose from
