I have a injector seal leack in my 1.8t, and i need to reseal them, couse i went to a mechanic and he is charging me 300 bucks for the work, but i wanna do it myself , to save money, wat tools do i need to take them out, becouse the mechanic was telling me that i need i special tool to take them out, is that true?
thanks for u help

 

get the bentley manual and look at how to do it, it lists everythinhg you have to remove and gives details, real nice for the DIYer

 

10mm socket topull the fuel rail then pull the injector and you will see the O ring seal, easy job

 

but to pull the injector out do u need any special tool? becouse the guy told me that i would break it if i didnt havd the tool?

 

no special too required

 

just did them. u DO NOT need a special tool of any kind. your mechanic is BSing u (typical scare tactic so he can land the job). Maybe he said HE uses a special tool, doesnt mean u need one. Mechanics have all kinds of "special tools".

As long as u have some workig knowledge of working on cars u will be ok. Just be cautious of how you disconnect things.

Basic procedure is: this is just general memory use a manual!

1 remove your gas cap to relieve pressure
2 remove plastic engine cover.
3 disconnect each fuel injector electrical plug (4)
4 remove 2 or 3? allen head socket bolts to fuel rail (attach rail to intake)
5 may have to move or disconnect accel cable to gain room
6 pull fuel rail with injectors straight out (will have ti use some force with a little jiggle)
7 you candisconnect fuel lines if u want to

will get a little gas messy-set up rags to catch any small residual fuel spills

each injector has two seals (top to rail and bottom to intake) the dealer sells them as a kit.

this job is not that bad at all

good luck

Yeah my crowbar is my "Special Audi tool" when doing things like replacing the fuel filter haha

 

Universal adjustment tool (AKA hammer).

 

Probably want to disconnect the battery as well.

Is there a fuse on the a4 for the fuel pump? If so, you probably want to pull the FP relay/fuse, and turn the car over a few times to relieve the fuel pressure. I know you said remove gas cap, but is that enough?
IDK, I just have had to do this on other cars when working on injectors, not sure about the a4.
