Disadvantages of the Audi DECA engine
Although the owners’ cooling system isn’t the most effective,
Although there are complaints about electrical issues, flashing usually resolves them;
Although there is no information on bullying, it is recommended on specialized forums to only use high-octane gasoline. Additionally, keep an eye on the radiators’ cleanliness because dirt quickly overgrows them.
