Air Fuel Mixture – If the air/fuel mixture is off, your Golf can stall out. Usually it’ll be a bad sensor reading, vacuum leak, or other problem that’ll cause the air/fuel mixture to be wrong. Bad Fuel Injectors – If the fuel injection system is allowing too much or too little fuel into the combustion chamber, than your Golf will stall out.

Why does my VW Golf keeps cutting out?
While there are several reasons that an engine would cut out while driving, the most common reason is a faulty sensor of some sort. If you find yourself on the highway or in traffic and your vehicle cuts out, you may be able to restart it while you are still coasting. This would be the safest way to get back to speed.
Why does my car stall when low on gas?
Low fuel pressure. If your car only stalls on inclines, then low fuel pressure is likely the culprit. This can be the result of clogged injectors, so buy some fuel injector cleaner and add it to your fuel tank as soon as possible.
What causes intermittent stalling?
Common causes of intermittent stalling may include a bad idle speed control (ISC) system, low fuel pressure, loss of ignition, vacuum or EGR leaks, or other problems we'll get to later in this article.
How do I get my VW Golf out of limp mode?
With limp mode you should have an EPC light on the dashboard. When you restart the car it will reset but it is not fixed. You can then drive again but if you try to use too much power it will trigger limp mode again.
Can EGR valve cause stalling?
Stalling when the engine idles like a rough idle is usually caused when the EGR valve is permanently open and is constantly letting exhaust gases into the EGR system.

Most of the time when this occurs it is due to a lack of voltage. It can be from a failing battery or alternator. Most of the time the issue is the battery.
Can a bad fuel pump cause stalling?
Overheating Engine If your fuel pump is dying it might overheat and this heat causes your engine to overheat. Unlike the radiator, which will overheat until it bursts the cap and spews scalding-hot coolant everywhere, an overheat caused by the fuel pump will stall out the engine.
Why does my car keep stalling when I stop?
If your car stalls when stopped, it could be air-related, fuel-related, or ignition-related. If the camshaft or crankshaft position sensors aren't detected, the fuel injectors aren't signalled to put fuel into the cylinder or the spark plugs aren't told to fire. Incorrect air readings could result in your car stalling.
How do I know if my VW is in limp mode?
The most common symptoms of limp mode are check engine light, reduced engine power, RPM limit, or stuck gear.
Will driving in limp mode damage car?
Limp mode, or sometimes called limp home mode and fail-safe mode, is basically a self-preservation mode your car has. This means your car has a serious issue and continuing to drive it can cause severe damage. The issue most commonly stems from its transmission.
Can low fuel pressure cause limp mode?
The driving behavior you outline (won't rev or achieve speed) may be due to low fuel pressure (high pressure circuit)/inadequate fuel supply, or the engine falling into "Limp Mode".
