What Are The Signs Of A Bad BMW 135i Ignition Coil?
When a BMW 135i ignition coil starts to go, the car tells you. You might feel shaking or jerks at idle, or your BMW could misfire while you’re driving. Sometimes the check engine light kicks on, often with a code that points to a misfire or ignition issue. You may notice the car doesn’t pull like it used to, or the gas pedal feels slow to respond. Fuel mileage can drop since the engine isn’t burning fuel as cleanly. If you spot any of these problems, it’s smart to check the BMW 135i ignition coil soon. Ignoring it could mean more headaches—bad spark plugs or even a damaged catalytic converter aren’t worth the risk.
How Often Should The BMW 135i Ignition Coil Be Replaced?
There’s no hard-and-fast rule on when to swap a BMW 135i ignition coil, but most last anywhere from 60,000 to 100,000 miles. Real-world driving, the weather, and your maintenance habits all play a role. Some drivers go longer, but if you’re getting more misfires or you’ve changed one coil and another soon follows, it’s probably time to replace the set. Around 70,000 miles, it’s not a bad move to have a look or replace them during a tune-up. Staying on top of these checks keeps your BMW running smoothly.
Can I Replace The BMW 135i Ignition Coil Myself?
You can— a lot of DIYers tackle BMW 135i ignition coil replacement at home. The coils usually sit right on top of the engine. Take the engine cover off, and you’ll see them lined up, simple to reach. Always unhook the battery first. Be gentle with the wiring connectors, and tighten everything to spec when you reassemble. Labeling each wire helps if it’s your first time. In most cases, this job saves money and gives you a better feel for your own car. Look up your car’s manual or a quick guide, and you’ll be set.
What Causes BMW 135i Ignition Coil Failure?
Plenty of things can bring down a BMW 135i ignition coil. Heat, oil leaks, and moisture can break down the insulation and lead to short circuits. Over time, just normal use wears the coil out. If your spark plugs have too wide of a gap, the coil has to work harder, which means it might give out sooner. Sometimes, if the engine runs richer or leaner than it should, that extra strain shows up as early coil failure. Checking for oil leaks and keeping your ignition system healthy goes a long way toward making these coils last.
Is It Better To Replace All BMW 135i Ignition Coils At Once?
A lot of people and even pro mechanics choose to swap all the BMW 135i ignition coils together. After one coil fails, the others often aren’t far behind. Changing the set brings back smooth power, and saves on labor—not to mention the hassle of getting stranded. If money’s tight and the others look okay, you can change just the failed one, but keep an eye out for more trouble soon. Matching coils mean fewer odd problems later, and you might save on diagnostic bills, too.
