In less than an hour, you (yes, you!) can change the spark plugs and ignition coils on your BMW, saving you a lot of money on labor. See how easy it is in this video...

the best thing about changing plugs is getting to use the bendy ratchet extention that lies often neglected in your tool box!.I love my bendy extention:)

I know I'm reviving an old thread but it should still be relevant. Should Ignition coils be replaced when plugs get replaced or only if a problem arises?

Usually you replace them if there is an issue, otherwise it gets horrendously expensive!

Of course we should also try and define the 'when' a problem arises.

Rather than wait until an issue becomes apparent it's good practice to check the error codes certainly once a year with a service and preferably every 6 months. This could pick up a fault with the ignition/wider engine management.

This could head off a bigger problem in a more timely manner for something that isn't yet apparently in regular driving.

Z3lda started to run on 5 a while back, so I got and fitted a new coil pack. Turned out the fault was with the connection rod!

Too right mate, you wouldn't want one of those small coil bolts dropping in there.:(

One thing I noticed when I did mine was that tightening plugs to the torque in the manual was quite a lot tighter than I would have done using 'engineers feel'.
