Hi,everyone,i own a Audi a4 1.8t quattro,2002 with the avj engine.2 days ago it started giving cold air even when the engine is warm.It is not losing water and gives hot air now and again.I noticed the temperature rise rapidly to dangerous and quickly turned it off but has not done this again.Can anybody help?Is it a water pump problem?

I have seen similar problems on other cars and its normaly the thermostat has gone..

You could get it VAG-COM for a fault code which should identify the problem..

Coolant level is fine and changed thermo stat about a year ago.

Could be the thermostat has gone again.. its not unheard of for them to pack in suddenly !!

Mine did a similar thing. Turned out to be the waterpump. Apparently it has a plastic impellor that becomes detached from the driveshaft, ie the shaft spins but the impellor doesnt. Pump was replaced under warranty
