Damage to the ignition coil. 
The silicone hose of the ignition coil must not be contaminated by fuel as this can lead to failure of the ignition coil. 
  • When working on the fuel system, cover the ignition coils with suitable materials and remove where required.
  • Do not oil or grease the silicone tube of the spark plug socket. Do not  use any protection or maintenance products (e.g. silicone spray, rubber care products, rust remover, etc.).
