Do you have to pay for spark plugs on Mercedes S600?
Not only do you need to pay for 24 of Mercedes-Benz’s finest spark plugs when your lustworthy S600 needs service, but you’ll also have to carefully remove the ultra-expensive Merc V12 coil packs — the units responsible for sending electricity to those brand-new spark plugs.
What causes the ignition coils on a Mercedes S600 to fail?
Double platinum plugs with a standard diameter core in a turbo V12 may cause the ignition coils and possibly the voltage transformer to fail. Worn spark plugs, plugs with too large of an air gap (center electrode to ground electrode) will cause the ignition coils to fail – the question is whether or not the failure is permanent or not.
Are there two spark plugs in a Merc?
While a single-spark-plug system would be fine for most engine designs, Merc needed to optimize its V12 for both power and emissions, and using two spark plugs per cylinder was a way to reach its goals. The rub?
Where is the VT / ICU located on a Mercedes S600?
The VT/ICU is located on top of the engine, in the middle, towards the front of the car Because it is nearly impossible to tell a coil pack failure and a VT/ICU failure we offer both of these units as rental/test assemblies. If the rental unit resolves your problem you can leave it in your car and purchase it.

How do you remove a spark plug wire?
Remove the spark plug wires. For this step, you will need the spark plug wire removal tool that we listed above under tools required. Otherwise, you risk damaging the spark plug wire and the spark plug itself. Remove the Torx bolt at the center of the ignition coil pack. Unplug the electrical connector from the coil pack.

How do you replace an ignition coil in a Mercedes?
They need to match with the letters on the engine. Remove spark plug wires from the old ignition coil and install on the new ignition coil. Firmly press the spark plug boot into the spark plugs. Connect the electrical connector. Tighten the bolt in the centre of the ignition coil to 8 Nm. Congratulations!
How many coils are there in a Mercedes?
You have three coils on the driver side and three coils on the passenger side on the six cylinder engines. In our case, we have an eight cylinder engine so you will see four coils on each side. Remove the spark plug wires. For this step, you will need the spark plug wire removal tool that we listed above under tools required.
