The diagnose equipment should be only used as a direction of the fault but NEVER as precise indication.

Some fault codes are triggered by other factors. Let's say I had a car with P0340 (camshaft position sensor). But, the sensor is ok.

Turns out to be a faulty valve switch solenoid (VVTi). So not all faults are just one thing with these modern cars.

I don't think EV will overtake ICE as alternative fuels should be introduced. EV is just a part of the start. I already see Volt on the scrapyard because of a broken battery. Car is only 3.5years old? So which car is making more pollution?

Because here in Europe an average battery pack will cost over 4000$ and the car after 4 years is 4000$. So economically its totaled.
