I mean technically, the “pops” is really indicative of poor tuning: extra, unburnt fuel makes it past the combustion chamber to the exhaust system and then “pops” due to the heat in the exhaust system, sometimes even resulting in flames out of the back of the exhaust.

Why does my BMW engine make a noise?
Low Oil Level: Your BMW’s engine components use motor oil designed to keep the moving parts like the camshaft, rocker arms, and others lubricated and running efficiently. If your oil is low, there is not enough oil to lubricate all of the parts as they should be. When this happens, you may hear a ticking noise.
Is it normal for a BMW engine to tick?

How do you get rid of engine tapping noise?
Simply changing your oil can also get rid of the tapping sound, as over time an engine that is neglected of maintenance will begin to clog up its oil filters meaning that a build-up of grime can again lead to a lack of component lubrication.
Why is my engine ticking while idling?
The engine’s cylinder head uses a series of lifters in order to open and close the valves. These lifters can get worn out over time, which inevitably causes a metal-on-metal ticking noise at idle and upon acceleration.
When I press the gas I hear a clicking noise?
A worn motor mount, control arm, or axle can all cause these sorts of symptoms. It may also be possible that the noise is related to the engine itself, however a close inspection would be required to determine if this might be the case.
Can you drive a car with a knocking engine?

Does engine knock cause damage?
Knocking can damage the surface of the piston, the cylinder walls or the crankshaft bearings, all of which are expensive to repair. Modern computer-controlled injection systems can correct your fuel mixture to prevent knocking, but at the cost of engine performance.
Why does my BMW rattle when I accelerate?

Can you turn off fake engine noise?
There are two ways to turn off the fake engine noise, detailed in plenty of forum posts here and elsewhere: 1) A dealer can do it for you, electronically turning off the “Active Sound Control” feature. 2) You can pop off an access panel at the end of the dash, reach in, and unplug the sound module.
What makes a ticking noise while driving?
The most common cause of engine ticking noise is low oil pressure. This is an indication that vital engine components are not getting adequate lubrication. Your engine may be low on oil or there could be a problem inside the engine causing the low oil pressure.
Why does my BMW sound like a jet engine?
If your car sounds like a jet engine in stops and starts rather than one continuous noise, it’s possible you have a leak in the exhaust. A hole in the exhaust system can take noises which are coming from the engine and make them louder.
Why does my BMW sound like a vacuum?
If your car’s engine suddenly sounds like a vacuum cleaner, you have a serious vacuum leak. All vehicles have combustion engines, and producing combustion creates vacuum pressure. This pressure is routed throughout your engine so that it can power components such as the power steering pump.
Why does my engine sound like a helicopter?
If your car sounds like a helicopter when accelerating, you may have a loose wheel, a brake problem, or leaky exhaust. Loose tire:A loose tire will wobble while it interacts with the road, causing the “whump, whump, whump” sound associated with helicopter blades.
Do bangs and pops damage engine?
The short answer is yes! The excess fuel added to cause the anti-lag and pops is not at all good for the longevity of an engine. Race cars regularly have oil changes, pretty much after every use, and you really do expect engine and turbo damage when running under extreme conditions and vehicle set-up in motorsport.
What causes engine crackle?
The crackle noise is a sign that your exhaust system needs servicing, or replacement if it’s not working properly. This could be caused by restrictive pipes and/or loose joints in the piping which need tightening. It can also be due to a defective muffler, which would need to be replaced.
What is a loud tapping sound in engine?
Low Oil Level, Oil Pressure, or Worn Engine Components Low oil, oil pressure, or worn tolerances in the valvetrain, can trigger a very distinguished ticking sound. People often call this “lifter tick.” The top end of your engine will suffer initially if you do not have adequate oil or adequate oil pressure.
How do you fix a tick on a BMW lifter?
BMW independently formulates its engine oils to properly lubricate the hydraulic lifters and prevent premature engine wear. If you are experiencing hydraulic lifter ticking “flush” the engine as follows: Replace the current oil and filter with a certified BMW brand. Drive the vehicle for about 50 miles.
Will an oil change stop engine knocking?
Q: Can oil change stop engine knocking? If your oil pressure is low or you have a low oil level, you’ll likely hear a splattering, tickling, or ticking noise from the engine. If this noise is from the valves, or lifters, adding or doing an oil change will stop the noise.
Can low oil cause ticking noise?
An engine with low oil or low oil pressure can make a ticking noise due to a lack of lubrication. If you are low on oil, it may indicate either oil consumption or an oil leak, both of which should be addressed as soon as possible. If you have low oil pressure, you will likely get a warning on the dash.
