Audi 100/5000 injector removal
Vistula
mid-1980s Audi 100 or 5000 (5-cyl engine with 'mechanical' fuel
injection)? According to Haynes they should just pull out. On those
models with rigid fuel pipe ends these can be used for leverage.
Mine however has the fully flexible fuel lines and affords no such
leverage nor can I get a decent enough grip to pull them out
(removing the inlet manifold seems a bit drastic).
Equally importantly, what is the best way to reseat injectors?
thanks in advance.

They do in fact just pull out. Some come out harder than others but they are
not held in by anythings except the O ring. Get something (like a screw
driver) underneath the flange nut that tightens the fuel line onto the injector
and pry against the valve cover. It WILL come out. The Audi tool for this
operation has a half moon tab that fits under the flange nut and a screw driver
is used for the lever. Replace the O ring and oil it before pushing it into
the injector seat. You'll feel it when it seats.

them, and if the motor backfires the lubed O rings will pop out. when you go
to get the new O rings make sure you get the newer Green (viton) style, not
the black ones that have been on the parts shelf for years............

Many thanks. I had already managed to remove one but the others were
proving to be tricky. I suppose it's just a matter of finding the
right size/shape screwdriver. I take it the larger O-ring near the
fuel line connection is the one to be replaced.
That said, apart from cleaning the exterior surfaces, is there
anything that can/should be done to injectors (commercially or
oneself) that will improve their performance/life?

There _is_ a tool available for the purpose...ask for a "VW injector
remover".

Replace them. I'm doing mine this year, as when I did the exhaust manifold
gaskets last weekend, I noticed the front two cylinders were running
rich...black exhaust ports. Others three were a nice tan.
