SV: New starter behaving strangely

Sun Aug 7 08:01:32 PDT 2011

What does the cold start valve have to do with this?

I hear the starter spin fast, but it doesn't make contact with the flywheel.

The starter is a rebuilt unit.

Like 25% of the time the little wheel inside the starter makes contact with
the flywheel,

and the engine starts.

...please tell me, where does the cold start valve fit into this?

Sounds to me like one of the wires is not making contact. I don't know how
the 100 turbo is wired as to the cold start valve (don't have bentley here),
but on the non-turbos the CSV gets power from the third wire to the starter.
If that wire does not get power during cranking, no cold start valve, VERY
hard starting. If you don't get power from that terminal on the starter
during cranking, hook the two wires together, and it will pull the needed
power through the ign switch. BTDT.

I have installed the insulation like on the original starter.
Did this give you problems?

Hera are the attached pics.

My mechanic removed my starter re-instlled but didn't put insulation back. I
have no problems yet. Have been driving in hot weather.

Erm... this may sound a bit stupid, but I just took it out of the box,
transferred the heat wrapping from the OEM starter to this rebuildt unit,
replaced some wiring that had started to get rotten, and put it back in...

Can you like basically draw me a picture of what you're asking?

Does the solenoid have insulation around it?

Replaced the starter on my 1990 Audi 100 Turbo Quattro (MC2-engine) with a
rebuildt unit,

and when I tried to fire the car up, the starter didn't start the car; it
just span like hell.

Tried to start a few times more, and on try number eight or ten the car
fired, and ran like it should.

Stopped the car, and back to square one. Now the car starts after the
second, third of fourth try - it varies.

My question is; is this just from the starter being "tight", being placed on
the shelf for a long time after being

rebuildt so it will work itself out - or is it a bad rebuild?
