Test injector resistances
Test process
   
–  Test injector resistances between contacts. Target value: 12...17 Ω.
  Note!
The resistance value is valid for approx. 20 °C. In the event of higher temperatures the resistance value rises.
If the target value is not reached:
–  Replace the faulty injector → Item.
The injectors are fitted in the reverse order, bearing in mind the following:
t  The O-rings of all the injectors must be replaced and lightly oiled with clean engine oil.
t  Insert the injectors vertically and in the correct position in the fuel distributor and immobilise them with holding clips.
t  Fit the fuel distributor with the injectors correctly fitted in the cylinder head and insert in uniformly.
