The signs of a leaking turbocharger system start with a lack of power or random misfires on Audi and VW engines.
Some customers may report electrical problems that might seem unrelated or in just one system. The issue could be animals biting wire insulation, cables and hoses. Animal damage primarily occurs on easily accessible and exposed parts.
On some 2012-2013 Acura ILX, MDX, RDX, TL, TSX and ZDX models, the stock gas cap can cause codes P0455 (EVAP system large leak) and/or P0456 (EVAP system very small leak detected). The gas cap may also be loose or have a stick-slip feeling when tightened.
Imagine a car without sway bars. The car would experience body roll around corners, but off road and in a straight line, the tires would maintain better contact with rougher roads at lower speed for better traction. However, at higher speeds, the body movement around corners would negate this effect. If you increased the spring rate, it would reduce body roll but would impact ride comfort.
The positive crankcase ventilation (PCV) valve is a little component that can cause big problems if it isn’t working. Neither your customer’s engine nor your job profitability will flourish if you don’t properly diagnose PCV leaks.
TPMS and keyless entry can be difficult to understand because these systems rely on transmitting, receiving and decoding radio waves. You can see wires connecting modules and components, but seeing radio signals takes a little faith in science.
Secondary air injection was added to vehicles in the late 1960s to combat air pollution after it was discovered that tailpipe emissions were causing smog in major cities like Los Angeles. The first systems were called “smog” systems, and the extra supply of air came from a belt-driven pump that was tagged with the name “smog pump.”
You know what rust and corrosion look like, but what is it? Why does it cause holes in some metal parts while causing others to seize? It is not a simple answer. Understanding the mechanics of rust and corrosion is critical in repairing the vehicles and preventing corrosion from happening.
By declaring a customer’s brake pedal pulsation complaint is caused by warped rotors is like saying the earth is flat. Both are cases where the observation of the person is based on a tiny piece of evidence that is false in nature and application.
