There is no real interval for changing an ignition coil. A coil is replaced when it is faulty. Although it is preferable, it is not essential to change all the coils at once.
Running a diagnostic tool can help determine which coil is at fault. The fault code obtained will indicate the cylinder number. Typically, you will have a fault starting with P03XX.
It is preferable to erase the faults at the end of the intervention with this same diagnostic tool.
Tools
Parts
-
-
unclip the 4 clips from the air box
-
pinch the lower collar of the oil breather and place it upwards
-
release the air box from the throttle body sleeve by pulling upwards
-
remove the air box
-
-
-
Blow or vacuum around the coils to remove dirt.
-
It is best to place a rag over the throttle body to avoid getting dirt into the engine.
-
-
-
using a small flat head screwdriver, lift the tab on the coil plug and pull to disconnect it
-
unscrew the coil retaining screw with a 10mm wrench
-
remove the spool by pulling it upwards
-
We can take advantage of this to blow the spark plug well.
-
-
-
position the new coil on the spark plug
-
A thin layer of dielectric grease can be applied to the ceramic portion of the spark plug to prevent moisture.
-
Tighten the coil retaining screw moderately (recommended torque 10Nm)
-
reclip the coil plug
-
You should hear a small "click" when the plug is properly engaged.
-
-
-
present the air box on the throttle body and the oil breather
-
Push the oil breather hose back in (right arrow in photo), pinch the clamp and slide it back down
-
re-engage the air box into the throttle body sleeve by pressing on it (left arrow in the photo)
-
You can lightly oil it to make it easier to put in place.

Do you know the Bougicord brand in reels, because I ordered Bosch reels from Oscaro, are they also reliable Bougicords?
It's hard to find information about the cylinder order on the engine. Is the 1 on the left or right when you're facing the engine with the hood open? Or even in the middle?
The P03XX code is very useful for targeting the cylinder in question, but without the RTA it is impossible to know where the offending cylinder is located...
Cylinder #1 is always the one against the gearbox. 2 in the middle and 3 on the side
Hello! It would have been good to specify which reel is #1, #2, and #3
I don't understand this comment. The coils are all identical and interchangeable. There is no coil #1, 2 or 3.
Concerning the harness, however, there is indeed an order. That said, the wiring is arranged in such a way that the connection order is absolutely obvious (look at the photo in step 5). The wiring being so short, I'm not even sure it's possible to make a connection mistake.
