Hi, just wanna hear from some on the above! How lasting is the ignition coils of your car before you need replacement? Does it affect your car 's ECU to cause permanent damage?

on my peugeot 308T, it's around 3 years before some of them failed. and it didnt cause any permanent ecu damage

WOW! 3 yrs that was fast ! I just had one replaced today coz the whole car jerk when cold start! My car is 5yrs old. W205 c250.

Few weeks to life time

5 Years 160k KM still going strong

this is the correct answer...

Not sure why, but most conti have ignition coil problem around 5 year +/- but Japanese can last. Never change any ignition coil for all my Japs - Nissan, Mazda, Toyotas, thr closest thst need to change are just coil plugs every 3-5 years

Boxer : hold my coils

Peugeot 308t - 125k km, ECU failed first before coil

Vw Passat - 110k km , failed ignition coil same time as ECU failure

Fiesta ecoboost, 102k km, failed ignition coil but ecu no issues

my swift within 4 yrs changed 3 set of coils...after that next 11 yrs ok...

Mine almost 6 years almost 140k km still going strong

But how's to be sure? Maybe one of them is nearly faulty, what is the symptoms if it is dying?

after cold start, whole car shake ! Torque is affected ! These are the two symptoms that i encountered ! There maybe more other symptoms . Mine got 4 and only one kong!

maybe yu race your car too often!

Did you change all 4 or only one?

What was the visible physical symptoms of the coil? Tear mark?

How about the plug cable?

VW.. anytime.
mine at year 6, 90k km.

ignition coils tend to fail faster on turbocharged cars.

Your car will choke similar to the experience of running out of fuel.

Not sure bro! Didn't get to see the damaged coil! I changed all at one go! Lazy to go SC too often! But was told that the dmamged coil affected the ECU! Lucky didn't damaged the ECU , if not really gong hei fatt choy! my car ECU cost RM 12k to replace!

Depends on what car. My 2008 Mark X already around 150-160k km are still using original coils. However on my previous crappy Livina, I needed to replace them TWICE within just 80k km! First time was just around 50k km, just a shitty car!

As for effect on ECU, no damage whatsoever if your COP goes bad.

Huh, which Swift you have? The ZC21 or ZC31? My ZC31 still running fine but not sure if previous owner had replaced it before or not, looks like still original.

Used to be a common problem for BMW, my E46 Banyak masuk workshop because of ignition coil, cost me about 4 grand and not counting other things until I sold it off...nice ride yes, pain in the ass..yes too

Just changed all 4 for my 2004 big light camry. Coz plastic connector got brittle after so many years. I think after 16 17 years never changed before for 250k.
