Gasoline Direct Injection: Total System Diagnostics
Modern gasoline direct injection (GDI) engines have two fuel pump opportunities. You still have an electric pump in the tank, but a high-pressure fuel pump is on the engine. These two pumps work in unison, so the correct quantity of fuel is injected directly into the cylinder. If either pump can’t generate the pressure or
Cooling System Leak Testing
What replaces the conventional water pump and thermostat is electronic thermostats and electric water pumps.
Fuel Pressure Diagnostic Service
Use a scan tool that can look at special direct fuel injection parameters and perform bidirectional tests.
Underhood: Stop/Start System Diagnostics
This webinar is part of “AAPEX Repair Shop HQ Webinar Series: An 8-Part Webinar Series.” Sponsored by AAPEX. A stop/start system can improve fuel economy by five to seven percent and lower emissions. For stop/start functions to work, five vehicle systems must work in unison for smooth operation. During this webinar we will cover how
Modern Cooling System Diagnostics: Pumps, Fans and Thermostats
All modern engines need a specific air/fuel ratio for efficient operation. But the mixture of air and fuel must be at the correct temperature inside the combustion chamber. If a cylinder is too cold, it will require extra fuel. Conversely, if a cylinder is too hot, the fuel and air could combust prematurely or produce

Audi Stop/Start Systems
Stop/start systems are here to stay. As much as some people complain about them, others really don’t mind them, and even like the improvement in fuel economy. Audi first equipped some models with stop/start systems as a standard feature in 2013. Just by looking at the starter, alternator or transmission, it is difficult to determine
