Can anyone tell me if its possible for me to change the pencil ignition coils on a renault laguna at home, without going to a garage? Is it a simple job of just unbolting the faulty one and slotting in the new one, or am I being a bit optomistic?
Well that is about it.
I watched the mechanic do ours. Basically he disconnected the coils one by one and listened to see if he could hear a difference in the engine sound.
If disconnecting the coil resulted in no sound change then that was the faulty one.
Took about 10 minutes.
