I think the bit you mean is the over-pressure valve. It will vent any pressure in excess of (I think) 12psi and light the turbo warning lamp on the dash. Can you post a pic of it please?

Yes, the correct name for it is the Charge pressure and safety (blow-off) valve. and basicily it vents any excess boost and lights a lamp on the dash in the case of excess pressure.

It was designed to have the hose in place so would be worthwhile refitting it in place to maintain the system integrity. Without it you will be venting charged air and loosing performance.
All the best, Peter. |
