My Crank Case Vent (CCV) for my 2000 Jetta TDI broke today while my wife was driving it. She said the car started losing power and RPM's fell off sharply. A temporary rubber hose with carefully sized fittings were used to help get her back in the road.

Should I be concerned about any damage to the car? Is it ok to run the car with a rubber hose until I can get a new CCV for it? Thanks.

As long as the hose seals the leak you should be OK.
The only thing you are missing is the oil trap function.

You can actually plug the end where it goes into you intake and run a heater hose from the top of your valve cover straight to the ground. That valve is only designed to release built up pressure in the crank case and doesn't have to go back into your intake. I have mine set up that way and it works just fine.

There are 2 negatives to deleting the CCV connection to the intake.
1. There will be an combustion like smell under the hood that may enter the vent.
2. There will be an oily deposit wherever the hose ends.
I tried it for a while and hooked it back up.

I had an oil leak and it caused me to spin on wet roads!
NEVER just let it dangle.
Get a BMW Cyclonic filter and install it. Saw a recent write-up on it.

You need 3-4 foot of 5/8" or 3/4" hose, the cyclonic filter (I bought mine for $12 from car-parts.com), a 90* plastic adapter 5/8" from NAPA designed for automotive heater lines, some metal to make a bracket, and a couple large hose clamps to attach it to the oil filter. You can attach it somewhere else if you desire; I attached mine there.

Temporary the way you have it is fine for a bit.

As with above, as long as the leak is stopped, it works as an OK temporary fix. However, best to get it sorted asap.

why would the car would have lost power? She had to pull off to the side of the road. Car didn't have enough power to continue on. Car regained power once the CCV issue was fixed.

I wonder if that caused a limp mode? Engine light come on?

Limp mode was likely enduced by the sudden increase in un-monitored air.
Basically you had a sudden boost leak on the low pressure side.

CCV is a direct entry to the intake that the engine did not expect.

Again, which component was actually broken?
If the hose crumbled I hope it didn't enter the turbo at all.
