Loose injectors?
« on: 27 October 2012, 19:47 »
Been investigating slight starting problems, and saw one was moving slightly more than the others, how do you access them can't seem to get spanners in them. Or are they supposed to move?

they push in and pull out on a 8v Digi once the retaining bolts (that hold the rail) have been removed

16ver use the old metal chrome type injectors 8vers would use green or grey tops usually plastic.
The seal has gone if they are loose I would order new seals before you go tugging hard on them!
scroll down some pictures on my project page even some with injector pictures!

Are you wobbling the actual injectors or the hose going to them?


The entire world is a Money Pit, you just have to pick yours.

Problem is some of the larger rubber rings have moulded it self to the collets (brass inserts)
I found the best way to remove them was push from inside out the manifold most people try really too hard and end up ripping off the end of the injector and falling into the manifold. For the sake of a gasket I took mine completely off and gentley pushed them out with a solid flat tool or wood piece. There are two rubber seals you need one thick donut one and a really thin one that sits on the end of the injector(see picture) these are the ones that are usually perished. I think donut ones are the hardest to pull out with the injector in and are the ones that is usually stuck. If yours wobbles it should pop out quite easily.....I say LOL!



Top tip lube up the rubber ring before inserting it goes past the collets by about 3-4mm much easier.
If not pused in properly it will piss fuel or let air in!

035 133 557a - bottom o-ring

They are called Collets you wont need them unless you have damaged them somehow some people change them as over time they wear down and cause air leaks or loose injectors from vibration. I personally dont think you need them just do the rubbers! I stuck them in here as future reference for other people!
Not cheap either for a set. I still have a few I didn't need to use, just incase VAG decide to stop stocking them LOL!
They sit around the manifold holes that your injectors get pushed into!
