Injector seal gone?

[The Swede]

I'm guessing I need a new injector seal? Anyone confirm?

I might as well do all 4 while I'm at it. And while I'm in there, are there any benefits to upgrading the injectors if I'm not planning to go higher than stage 2 or is it just a waste of paper?

Mine are doing the same so I would be interested if its worth replacing the seals or not.
I wouldn't think putting bigger injectors is worth it if your not going after big power as the car probably wouldnt fuel right until its been mapped?

I wiped away some of it and then went for a drive just to see how much of a leak there is and the area I wiped clean is bone dry after a half hour spirited drive. No codes and runs as smooth as ever so it's probably been like this for a while. Saw it by chance as I was popping in some new plugs with the TFSI coil packs my friend gave me.

Sounds like its just built up over time. Mine runs fine too so I think I will leave alone then.

Yes injector seal, it will cost you about an hour to swap them. Did this not too long ago. Very straightforward job.

Check straightaway if the injector cups are without cracks!

Havn't had the injector out to have a look but I just ordered new seals and inserts/cups for all 4. Might as well!

Good decision

Did you replace the seal on the top of the injector too? I assume the injectors just pull out of the manifold once you have removed the fuel rail and Unclipped them from the rail?

Yes, replace both of them (top and bottom of injector).

[edit]
Unclip the injector from the rail and pull it out of the cup and injector (dont pull too hard, just wiggle it out). I pulled them out of the cups first and unclipped them one by one (you can only service one at a time innit)

Ok thanks. Are both o rings the same part number?
