Why does my Passat vibrate at idle?
Might be the balance shaft chain. My Passat had a nice vibration at idle before i did the upgrade to the gear. I might add even a bad engine mount or loose hardware could cause the vibration. Bad injector or valves might need to be adjusted. Tho i think you said you checked thos right?
Why is my VW stuck in limp mode?
Vehicle Speed Sensor - If your Volkswagen has developed a harsh shift between gears or is stuck in emergency mode (limp mode), the vehicle speed sensor (VSS) may be the problem. A signal from the VSS is sent to the Powertrain Control Module (PCM), and the loss of the signal can cause one or more problems.
Why does my car shake when put in reverse?
It gets crazier when you engage the reverse gear because of the higher pressure inserted on the mounts. Vibrations can also occur when the rubber parts of the transmission melt due to oil leakage from continuous friction in the gearbox. This is caused by the many activities going on in it.
Why does my car shake when I take off in first gear?
It's probably clutch related, for example due to worn out friction material and/or a pressure plate defect BUT it's also possible that the motor mounts could be implicated and the engine as well if the engine is bogging down (due to an ignition, fuel, or air induction fault) under the load experienced when you start in ...
Why does my VW Golf shake?

Why does my car shake in second gear?
This is often a sign of low transmission fluid or a faulty transmission control solenoid. As you know, automatic transmissions use pressurized hydraulic fluid to change gears.
What is clutch shudder?
Clutch chatter is the initial shudder that occurs when a faulty clutch disk or clutch component first engages. This shudder or vibration may vibrate throughout the entire vehicle. It's often the result of worn or contaminated clutch components.
Can a bad CV joint cause vibration when accelerating?
When the inner CV joint is damaged or begins to fail, you will notice your car vibrating under hard acceleration. As it gets worse, the minor vibrations turn to violent shaking when under load. Damaged CV joints usually occur because of a tear in the joint boot.
How do I fix my car shaking?
If vibration is felt at certain speeds, the tires may need to be balanced. If the tires are wearing unevenly and causing the car to vibrate, the driver may need a tire rotation. In some cases, the driver may need new tires to solve the problem of vibration.
Can bad spark plugs cause car to shake?
Improperly functioning spark plugs cause an uneven burn of fuel in the engine, resulting in fluctuating RPMs and a louder noise. You might also experience increased vibrations of your vehicle while sitting idle or while traveling at low speeds. These vibrations originate from the engine and can shake the entire car.
Can bad injectors cause vibration?
Engine Vibration A compromised fuel injector will cause the corresponding cylinder to not be able to fire. This in turn will cause the engine to vibrate as it tries to finish each cycle without adequate fuel.
How do you clean diesel injectors?
The best way to clean fuel injectors on a regular basis is to use a diesel fuel cleaner additive. This can be added to the fuel tank periodically to cycle through your engine. If done regularly, maybe once or twice a month, it can keep gunk and debris from building up in your fuel injection system.
Does a bad fuel pump make your car shake?
Q: Warning signs of a bad fuel pump. Like sputtering when idle. Bad fuel efficiency. Shaking when at higher speeds.
What would cause a diesel engine to surge?
If an engine is not getting enough fuel (this is called “running lean”), due to fuel pressure (regulated by the fuel pump and regulator), restricted fuel injectors, a vacuum leak or really anything that throws off the fuel mixture going in to the engine, this can cause the surge.
Can bad diesel cause rough idle?
Dirty Fuel Injectors This can lead to an imbalance in the levels of air and fuel in the engine, which will result in rough idling.
What causes diesel engine hunting?
Engine hunting and surging at idle is usually caused by a fuel delivery, air leak, or governor system problem. Cleaning/overhauling the carburettor, adjustment of the governor, and/or changing the air filer may be required.

It could be the mass airflow sensor, idle control sensor, or O2 sensor. If your check engine light's on, have it hooked up to a diagnostic and see what the engine codes say.
