🇬🇧Corsa Coil Pack Replacement (engine Misfire, Jerking)

The Vauxhall / Opel Corsa e 1.4 2014 was running rough and jerking intermittently.
When you lift the bonnet you can hear a clicking sound coming from beneath the engine cover, every time you click, the engine shakes slightly. this is a tell-tale sign that the coil pack is faulty.
It is a common fault on this vehicle due to water ingress into the spark plug Chambers, causing corrosion to the coil pack contacts and the spark plugs.
In this video I show how to remove & replace the coil and spark plugs.
This fault is exactly the same on the Corsa D and Corsa E 1.2 and 1.4 engines.
