VIDEO: Direct Injection And Oil
Andrew Markel shows how the fuel pump, variable valve timing, and oil well work together, and how the failure of one of these components can lead to codes and other problems.
Audi Direct-Injection Issues & Carbon Deposits
In 2006, we saw the first of the direct-injection cars. VW and Audi located the injectors directly into the combustion chambers for greater efficiency. By this time, we had been seeing variable valve timing for at least six years, and there were a few cars that had variable intake runners. The new A4s and Passats had both and, in addition to the in-tank fuel pump, they had a cam-driven, mechanical high-pressure fuel pump that ran the fuel pressure as high as 120 bar. They are great cars, but began to exhibit a few problems that we started to see after a few years.
Import Oil Specification Primer
As engine technology has evolved and fuel efficiency standards have tightened, oil specs have increased in importance. Using the wrong viscosity could set a fault code in some applications or interfere with the normal operation of the variable valve timing system.
Diagnosing Misfires
What if there are no codes and a misfire is intermittent? This is where it gets complicated.
