Q: Very Tiguan turbo charger, replaced still idles ruff.

Told by dealer turbo is failing. Needs replacement, so we replaced and it still has issue

My car has 100000 miles.
My car has an automatic transmission.

There are a number of things that may cause a rough idle. A rough idle may be caused by things such as low fuel pressure, low voltage to the fuel injectors, dirty fuel injectors, a vacuum leak, a faulty Oxygen sensor, dirty or failing idle air control valve, a faulty camshaft or crankshaft sensor, faulty spark plugs or wires ad many other things. Any of these possibilities may relate to fuel or spark problems that will disrupt the normal combustion process that would otherwise allow the motor to run smoothly. You may notice the motor running a bit rough or shaking if any of these components are not functioning as they should. I would recommend having an expert from YourMechanic come to your location to diagnose and inspect your vehicle.
