Good post but on the cis injection you first de pressurise the fuel system. Start engine and pull the fuel pump relay ,wait till engine as stoped.Now you can go about removal of the injectors. Telling you all about this ,as its my next job. Edited by optimusprime, Thu May 28, 2015 11:14 am.

Thanks for the write up. Followed it today and successfully replaced all six injectors and seals. Even managed to change the air hose the cold start valve plugs into whilst everything was out of the way. Can always rely on the forum!! |

Good Job ! The only thing we do in the garage would be change the O rings too as they can leak and go hard just a few pence it's worth it, |

Did those along with the plastic head inserts. I tend not to scrimp on the car. Got the Bosch injectors online from Berlin for €26 and everything else from Mercedes Brighton. |

Agree, best to change O rings as well. How much did you pay for the plastic sleeves? I decided not to change those. |

You should always change the seals/ o rings, it's just an easy to do & worth it. |

£93 for a full set of 2.5-16v Bosch injectors. Plus £8.14 cashback, so £85 essentially. http://www.carparts4less.co.uk/ http://www.topcashback.co.uk/carparts4less/ Bargain I thought, only found out because my friend bought some for his turbotechincs MK2 Golf Edited by Haris, Wed Aug 5, 2015 11:25 am.

I've tried to do this job today. Strip down started ok to the point of undoing the olive nuts prior to unfastening the allen bolts two of the six of them felt like either they were going to cross thread or the pipe's were going to twist and snap like brake pipes do when there corroded. There is no visible corrosion on any pipes, its just that four of the olive nuts cracked and came undone the other two just didn't feel right. Anyone experienced a similar problem or any ideas what I should do with them? I've sprayed penetrating oil into the olive nuts gave I little time and no success maybe try them again tomorrow. |

Could try taking the pipes off from the fuel distributor end then getting the injector and pipe out together, whack em in a mini vice and have another shot at it with a nice flare spanner. One of mine felt a bit mushy to take off but it was just the fact that the injectors in a rubber bung and it was moving about a bit in the injector retainer bracket mabob with the slack. If it ends up damaging a pipe or injector throw me a PM. I've got a few m103 Kjet spares. |
