The catalytic converter in your BMW is responsible for controlling the emissions from your BMW.
However, a bad catalytic converter in your BMW can create havoc & lead to other serious issues.
Here are the top symptoms of a bad catalytic converter that you will come across in your BMW.
A drop in acceleration is perhaps the first thing you will notice whenever the catalytic converter goes bad.
However, the lack of acceleration can also be caused due to underlying issues in your high-end car.
Nevertheless, upon inspection if you find that the other parts are functioning fine, then it is the catalytic converter that is faulty.
when you are taking your car for an emission test and it fails continuously, then it must be a cause of concern.
Now, the problem lies in diagnosing what part of your car’s emission control system has failed.
A bad catalytic converter being the reason behind the failed emission test cannot be ruled out.
A malfunctioning catalytic converter is often linked to starting issues in vehicles.
Whenever the catalytic converter is clogged, you will notice that your car starts initially, then it shuts off.
This is because a clogged catalytic converter leads to a buildup of excess fuel in the engine & it creates starting issues.
The engine requires an adequate flow of oxygen and fuel for the combustion process to take place.
However, a bad catalytic converter plays a spoilsport and restricts the flow of air into the engine.
This inadequate flow of air into the engine severely impacts the combustion process & causes engine misfiring.
There are several warning lights on the dashboard of your vehicle & the check engine light is one such warning light.
A bad catalytic converter can definitely cause the illumination of the check engine light.
However, the warning light can illuminate due to a host of factors & proper diagnostic tools are necessary for pinpointing the issue.
These are some of the symptoms associated with a bad catalytic converter in your BMW.
