Disadvantages of the Audi RT engine
The K/KE-Jetronic injection system is the primary cause of all of this engine’s issues;
Unstable engine operation is typically caused by air leaks or idle valve contamination;
Dirt and a lengthy drive with little fuel in the tank terrify the fuel pump;
Additionally, many engine failures are linked to ignition system component failures;
Hydraulic lifters frequently knock after 200,000 kilometers and need to be flushed or replaced.
