Removal and installation the cable connection of pump-injectors and glow plugs (VW Passat B6)

Removal

Remove the engine cover.

Attention: Installation/dismantling of the cable connection is only possible after unscrewing/screwing the fastening brackets. When removing the cable channel from the brackets, these brackets are bent, and an excessively large gap can lead to a cable break. This applies to work on replacing pump injectors, as well as to all types of work for which it is not necessary to completely disconnect the central plug.

Note: For piezoelectric injectors, the plug connection must only be removed using a puller.

Remove the cylinder head cover.

Disconnect the central plug connection on the cylinder head.
