I have a manual 2000 1.8t no crank. The battery is holding a 12 V charge at the moment.
Here's what has already been tested:
1) battery clamps and cables
2) battery
3) starter is getting power from battery
4) solenoid clip is sending juice to solenoid
5) starter/clutch relay
6) clutch switch (receiving 12V from ignition switch)
Are there any further suggestions for trying to diagnose this issue.
7) starter bench tested

So, when you say "no crank"; do you mean the starter motor is not spinning or the starter is spinning but the car won't start?

We have seen starter switches fail/crack, wiring/plug melt and link between the key tumbler/switch break (part of the steering column lock assembly). Once you remove the ignition switch you can turn it with a screwdriver and isolate the link/key tumbler. Here is a thread: that can help you with the switch assembly:

Yes when l say crank l mean the starter motor, which tested good on the bench, is not turning... l dont think its the ignition switch because l got volts on 2 separate test that required turning the ignition... plus windows , radio etc is still functioning.

Well, the switch is a easy to get to part; it is a known issue and they don't cost much, so it is worth a try and look. Aside from that; you seem to have done thorough testing, may be wiring related to the wiring harness? As for testing the starter; did you just hook it up to battery to see if it would spin or take it to a parts store and use their bench testing machine? I know; when my starter was going out; it progressively would "click", then start working after a number of cycles of the ignition switch and eventually, stopped working altogether. A voltage drop and load test; maybe, a good thing to do and see if everything is ok.

Here is a good video; going over the testing procedures:

From what you are saying; your testing, sounds like the wiring and voltage, to the starter is ok. If that is the case; I would have the starter tested on a actual dedicated starter testing machine and see if it really is ok. Is the starter original and how many miles are on the car? My starter lasted around 70k and 10-12 years. I replaced mine with a genuine Bosch unit; that was rebuilt, Bosch is the oem for Volkswagen at the factory and best quality you can buy. You can look up the correct starter for you car here:

Here are some service manual links; that may be helpful:

I actually dont hear the solenoid click when l turn the key, however, l am certain its getting power as l tested the clip that attaches to power it.

215000 miles well taken care of runs like a champ... yes starter was bench tested at AA auto on a dedicated machine....everything points to a starter so l even bought a new on and put it on still no crank

Smh ignition switch was the culprit was sending good voltage when tested but when l checked it while it was out l noticed the dash flicker, l happened to have another new one that l never returned from previous change a year ago so l popped that in and voila thanks uch comrades

Bingo! Yeah, that is why I emphasized this; it is a VERY common problem with a no start issue. As you noticed; it can be intermittent and fail inside, the plastic case will crack, causing connectivity problems inside the switch. Glad you got it fixed! :)
